Linux

A few more thoughts here:

• for a first Distribution, Ubuntu is fine, too. Also, you could ask people arounf you what they know best und whether they like to help you. For example, Debian is a bit harder to install but is rock solid once it runs.
• if you are concerned about security, you should practice a strict separation between trusted software installed by you, and untrusted data presented to you via web, mail or Internet. Never run untrusted code. Windows blurs that line and this is fatal.
• In respect to hardware support: Most standard PC hardware will work very well with Linux, even old scanners that have no more Windows driver support. NVidia is the bad exception, and the bad rap is still justified because of Wayland, the new graphics display server. If you are not really poor you might consider to buy something better. The hardware support landscape is different for laptops. Here, refurbished Lenovo Thinkpad or Dell laptops are first choice, and also best value for the money.

Any change brings some pain, that's unavoidable, but it doesn't mean it will not be interesting as well.

All your concerns are valid and Linux handles all these well except:

If you play competitive games with kernel anti cheat it will simply not work on Linux courtesy of the game developers.

Linux is fully capable of running the game and the anti cheat but the game developers restrict it. Notable games are cod, fortnite, apex legends.

A notable competitive game that works on Linux is cs2 although you won't be able to run 3rd party anti cheat like FACEIT as far as I know.

You can use the proton site to tell you how many of your games on your steam library are playable on Linux.

I'm on my 8th month or so using Linux to game and I've had no issues, most popular games will work. Most niche games use very simple tech like SDL and will just work.

Wine essentially creates a fake windows environment and handles a lot of internal API calls by kind of redirecting them to existing Linux services, so a lot of windows stuff will just work.

As for security. You realize most of the Internet runs on Linux ? Practically the majority of the internet is hosted on Linux machines.

As for a distrto there is no optimal choice you can make.

You can pick Ubuntu, Debian or Mint and find yourself disappointed in how restricting the power user experience is.

You can pick arch or cachy for the latest wine improvements but find yourself lost in how to handle the OS in case something goes wrong.

I personally think cachy (rolling release) is the best for gaming but you could encounter issues (skill issues really) that might frustrate you. These issues would lead to growth and improvement in your understanding of Linux but if all you want to do is game and you don't care about understanding computers then it might not be for you.

Will my ability to play games be significantly affected compared to Windows?

So far, my experience on this depends on your graphics card. If you're using AMD, you shouldn't be too significantly impacted. If you're using Nvidia, god help you. In my experience trying to get games running on Linux with an older Nvidia card, you'll have a lot more fun bashing your head into a wall until the wall breaks.

Will my ability to play games be significantly affected compared to Windows?

Depends on the games you play. Because of things like DOSBOX and Wine, it is sometimes easier to get DOS and early Windows games running on Linux than it is Windows. Valve's Proton compatibility layer allows games written for Windows to Just Work^TM^ on Linux. My diet of nerdy factory building games and indie titles works perfectly well in Linux, my cousin who plays Bethesda and EA games ran into more irritations. The major compatibility barrier is competitive online multiplayer and anti-cheat systems. Many developers intentionally exclude Linux compatibility. The game runs fine, but you'll get banned for doing it.

Can I mod games as freely and as easily as I do on Windows?

Probably, depends on the game. I didn't have much of a problem modding Kerbal Space Program or Satisfactory, the communities offered mod managers that worked perfectly well.

If a program has no Linux version, is it unusable, or are there workarounds?

My suggestion would be to go full native if you can. Like, Adobe Photoshop isn't available on Linux, so instead of trying to make it work, give GIMP or Krita or one of several others a try. Increasingly, things like Slack are Electron apps, which basically run as a glorified web browser, so they're fairly easy to port to Linux and it's becoming increasingly typical to upload them to Flathub.

Can Linux run programs that rely on frameworks like .NET or other Windows-specific libraries?

Yes, through a compatibility program called Wine, which I've already mentioned. Though again I would recommend going for native applications than trying to use Windows software on Linux.

How do OS updates work in Linux? Is there a “Linux Update” program like what Windows has?

Short answer: Better than Windows does.

Different Linux distros will handle this slightly differently, but generally speaking your system will come with a thing called a package manager. It's basically an app store but everything in there is free. The package manager handles updates for the OS itself as well as the software you've installed, up to and including updating to the next version of the OS if applicable. In fact as I write this, my computer is asking if I want to upgrade to Fedora 42.

It's also not as onerous as Windows updates; most of the time it'll update software, you can use the rest of the system while that's happening, and it'll finish and it's fine. Sometimes it'll say "must restart computer for changes to take effect" but it won't force or nag you to do that. You can come to a stopping point in your work, then do a normal restart. None of that "Updating your computer 1 of 7..." it just does a normal boot in a normal amount of time.

How does digital security work on Linux? Is it more vulnerable due to being open source? Is there integrated antivirus software, or will I have to source that myself?

Linux has a system of permissions, a bit like how Windows will sometimes ask you to run things as Administrator. Linux has had that concept longer than Windows has, Linux will call it the Root or SuperUser.

Increasingly, sandboxed applications that run essentially in their own virtual machines are being used to limit what an application can access. Flatpak has a system of permissions not unlike Android, where you can say "No this app doesn't need camera access."

We get a lot of security from having a package manager we actually use. Linux users aren't in the habit of downloading random .exes from all over the internet. Software in the repos is vetted and signed. Don't run code you don't trust.

Few Linux systems come with built-in antivirus software. Conventional wisdom is it isn't needed. Antivirus software does exist for Linux, but it's often to detect Windows malware in server traffic. For an end user desktop it's not necessary.

Are GPU drivers reliable on Linux?

AMD publishes their drivers directly to the Linux kernel. My 7900GRE Just Works^TM^. Nvidia tends to be a bit more of a pain in the neck. Your system will likely come with the open source Nouveau drivers, which will run but possibly not very well, and you'll need to install proprietary drivers, which...the method you go about doing that varies from system to system.

Now, I had a hell of a time with the hybrid graphics on my laptop, but I think that's another story.

Oh, yet another story: on my GTX-1080 in my previous computer, I started to have an issue with a new monitor I bought. Turns out the card needed a firmware update or it wouldn't let the computer boot with a late model DisplayPort monitor attached. Not a driver update, a firmware update. Nvidia does not publish the tool to do that for use in Linux, so I ended up taking the GPU out and borrowing a Windows computer.

Can Linux (in the case of a misconfiguration or serious failure) potentially damage hardware?

I think I could use dd to wear out an NVMe SSD via excessive writing. But basically no. You're not going to flip a switch in a settings menu and hear a bang from your case.

And also, what distro might be best for me?

I would recommend trying several. A few of my favorites over the years have been Mint Cinnamon, Fedora KDE and Ubuntu Mate.

Just an addition to all the long comments already here:

There are some games that don't work on Linux, mainly big corpo multiplayer titles. https://areweanticheatyet.com/

Windows 10 LTSC IoT might help. (This gets recommended a lot on lemmy I noticed) : https://massgrave.dev/windows_ltsc_links

It's not forbidden to set up dual-boot. I would recommend using Linux as your main OS though.

Will my ability to play games be significantly affected compared to Windows?

That will depend on the games you play, and what platform you use. If you are using Steam, you can enable the proton layer have more access to games, but if the game in question uses any type of kernel level anti cheat chances are it's not going to work.

Can I mod games as freely and as easily as I do on Windows?

Depends on what you are used to, if you are using mod managers and which ones.

If a program has no Linux version, is it unusable, or are there workarounds?

A lot of work has been done with WINE, games on Linux, and Proton. You'll need to do a little bit of reading to see if it can work on Linux, but the community can often be awesome and already have found a solution. There are also a lot of great alternatives to Windows/Mac only software you can try.

Can Linux run programs that rely on frameworks like .NET or other Windows-specific libraries?

Depends on your distro but most can install .net, you'll need to do a bit of reading.

How do OS updates work in Linux? Is there a “Linux Update” program like what Windows has?

Yes, there are package managers that you can use to install and update software, some distro's even have a shop like interface.

How does digital security work on Linux? Is it more vulnerable due to being open source? Is there integrated antivirus software, or will I have to source that myself?

I've only ever had to use a virus scanner twice in my Linux journey and both of those times it was on a server. Because Linux is open source everybody can see what is going on in the code and this way bugs or security issues can be found and patched quicker.

Are GPU drivers reliable on Linux?

Depends, if you are using AMD you should be fine, Nvidia has functioning drivers as well, I can't speak for Intel ARC support because I've never used it..

Can Linux (in the case of a misconfiguration or serious failure) potentially damage hardware?

I've never broken my hardware, but I've broken my system a few times by ignoring the warnings the system gave me, always got it to work again.

And also, what distro might be best for me?

Linux Mint might be a good one, the Cinnamon is great for beginners, but there are many flavors you can choose from. Start with a live system which will not require you to install anything just yet, but you'll get a feeling for how everything works. After trying it out live you can decide if you would like to install it. But remember that when trying it live you are limited in what you can do.

Your questions will have different answers depending on which flavour of Linux you choose.

A good chunk of windows programs can be run using a program called “WINE”. WINE is just a command line program but you can get a GUI version easily.

Updates depend on your flavour but Debian based Linux (like Ubuntu) you just type “sudo apt get update” and then “sudo apt get upgrade” and bam everything is updated. No restart required.

If a program doesn’t work in Linux there can be workarounds or alternatives but that really depends on what program you are talking about.

You can play almost every game that exists on steam on Linux with the exception of games that have kernel level anti cheat like some competitive multiplayer games.

You’re arguably safer security-wise on Linux. Most people are on windows so that’s the majority of all viruses. Your security updates are included in system updates. No antivirus required.

I have never heard of Linux damaging hardware. I don’t think you need to worry about this.

Recommendation: get Bazzite. It’s a special type of Linux that is closest to a windows experience than anything else. It won’t let you do dumb things and mess up your install. It has all NVIDIA drivers preinstalled as well as gamepad drivers and everything you’d need for gaming (including dock support). It’s a no configuration needed OS. Linux on easy mode. You don’t even need to use the command line ever. Updates and apps are installed through the Linux equivalent of the Microsoft App Store (except this time it is great and doesn’t suck). And I say this as someone who only used windows until 15 years ago I messed around with Ubuntu and other Debian based Linux distributions.

As you can search the answer anywhere most games that don’t have kernel level anti cheat work.

Most programs can be run but not all.

Others have already answered your questions, so I just wanted to add that the Linux community is based on sharing and cooperation, mainly though Open Source principles, but also in most other ways. From personal experience, I would say that the community is pretty much always willing to help out when you experience issues. There's always someone willing to share some insight.

Will my ability to play games be significantly affected compared to Windows?

Yes, there are way fewer games than on Windows, but support has been growing in the last few years

Can I mod games as freely and as easily as I do on Windows?

If the tools you use are available for Linux, then no problem

If a program has no Linux version, is it unusable, or are there workarounds?

You can use WINE (Wine Is Not an Emulator) to run some Windows apps. You can check compatibility here: https://appdb.winehq.org/

Can Linux run programs that rely on frameworks like .NET or other Windows-specific libraries?

.NET (Core and newer versions) is fully supported on Linux. Other Windows-specific libraries might be a problem unless they work through Wine

How do OS updates work in Linux? Is there a “Linux Update” program like what Windows has?

Yes, most desktop environments have a graphical interface for settings and updates

How does digital security work on Linux? Is it more vulnerable due to being open source? Is there integrated antivirus software, or will I have to source that myself?

It's actually the opposite. Since the code is open, more people are checking for vulnerabilities, making it more secure than proprietary systems. In general, Linux users don’t need antivirus, as most malware targets Windows or macOS, and Linux malware usually needs privilege escalation

Are GPU drivers reliable on Linux?

That’s debatable. Everyone has different experiences depending on their hardware and distro

Can Linux (in the case of a misconfiguration or serious failure) potentially damage hardware?

Nope

And also, what distro might be best for me?

Since you have a gamer profile, I'd suggest Pop!_OS (https://system76.com/pop/). It's based on Ubuntu and has good support for gaming and creative work

#1 was true more in the late 90s to early 00s. The operating system has matured quite a bit since then.

I love Debian, but I hear a lot of people suggesting Linux Mint for new users. If you're afraid of committing to a change, grab a cheap used system to try it out. Just know that if you have better hardware, itbwill really shine.

Without trying to be exhaustive:

But all I know about Linux is 1: it’s a cantankerous beast that can smell your fear and lack of computer skills and 2: that’s apparently not true any more?

Exactly.

I’m pretty much a fairly casual PC-user, I don’t do much more than play games.

Noted.

Will my ability to play games be significantly affected compared to Windows?

Your queries on which specific games work and don't work should be answered between the databases of ProtonDB, WineHQ, Lutris and Are We Anti-Cheat Yet?. Note, however, that these are not necessarily exhaustive (even if put together); e.g. after visiting the aforementioned websites, you might think that Roblox can't be played on Linux. But it's simply one of the many games that exist in the compatibility blind spots between these databases; as the excellent Sober isn't accounted for.

Can I mod games as freely and as easily as I do on Windows?

There will definitely be a learning curve to be had. Though, AFAIK, there's nothing that outright prevents you beyond an initial (and potential) knowledge gap.

If a program has no Linux version, is it unusable, or are there workarounds?

Wine is your best friend in these cases. Or, an alternative. Note that -again- compatibility blind spots in these databases continue to exist; like this significant one.

Can Linux run programs that rely on frameworks like .NET or other Windows-specific libraries?

Again, Wine comes to the rescue.

How do OS updates work in Linux? Is there a “Linux Update” program like what Windows has?

This depends entirely on the so-called Linux distribution you end up installing. Some opt to do updates automatically (perhaps in the background even), while others simply prompt the user whenever updates are available. Yet others expect the user to do them manually. What are your preferences in this regard?

How does digital security work on Linux? Is it more vulnerable due to being open source? Is there integrated antivirus software, or will I have to source that myself?

This is somewhat of a controversial topic thanks to articles like this one. Note that while the article continues to be shared and thus remains 'popular', the fact of the matter is that at least some parts of it have become outdated since. Refer to this (more recent) article as an addendum. The gist would be that Linux might be secure enough for your intents and purposes. But this depends entirely on what you intend to use it for. Downloading and executing random files from the dark web is probs a bit much and not something any OS would appreciate. But playing your games through Steam and surfing the internet should be fine unless you're somehow targeted by a resourceful adversary. If you didn't worry too much about this on Windows and thus went with the default settings -so no hardening whatsoever-, then popular distros like Fedora should be more than fine for your use case. However, if you require more than that, then you may find solace in the fact that projects like Kicksecure and secureblue do exist. (There's also Qubes OS, but I'll assume that's too hardcore.)

Are GPU drivers reliable on Linux?

In most cases, yeah. Historically, Nvidia used to be a pita. And, frankly, continues to be for some peeps. But it has improved significantly over the last couple of years.

Can Linux (in the case of a misconfiguration or serious failure) potentially damage hardware?

Any bad software (irrespective of platform) can potentially damage hardware. Linux is no different in this regard. Though you shouldn't have to worry about this unless you intend do some janky stuff.

And also, what distro might be best for me?

As gaming seems high on your list, consider Bazzite.

Hello there 1- It really depends on your build, distro and drivers being used. Some benchmarks show Ray tracing causes performance drop compared to Windows.

2- There are mod managers here and there but, honestly I don't mod so I don't know anything about it.

3- If a program doesn't have Linux version, there might be Linux alternative. Those alternatives sometimes might not be on par with their counterparts though. Adobe products are one bit example.

4- Applications developed with .NET may be built on Linux through Mono framework, as long as they are developed as portable. For native Windows programs, there is a compatibility layer named WINE, but it won't guarantee that every program will work. It may support games as well, but for games Proton is more preferred. Proton is Valve's official tool anyway.

5- Distributions' package managers will manage updates, either application updates or system updates. Most distros will also notify users about updates, however installing them is up to user's decision. Universal package managers like Flatpak are responsible their own updates.

6- Linux is way more secure than Windows for being what it is. Being an open source does not inherently mean that it's secure. But open source softwares are generally peer reviewed by public and they are often recommended fixes thus if there is any vulnerability, it's fixed more quickly. Antiviruses are not needed, not because there is not Linux viruses though. There is ClamAV anti-virus, also there are proprietary AV applications, if you still need. AV's are mostly ineffective in today's technology.

7- AMD drivers, for example way more reliable than their Windows ones. Nvidia also made a lot of progress in recent years, so yes. There might be still some issues, lack of features.

8- No, it cannot.

9- For a beginner, Linux Mint is and always has been best choice for start, in my opinion.

It's literally be just as simple as choosing a distro, preferably a just works one or something thats piss easy to install like Linux Mint, Fedora or OpenSuse.

Then you choose your Desktop Environment, from which you can choose either KDE Plasma, XFCE, GNOME or the new COSMIC desktop environment (still currently in beta so not recommended js yet) which you can choose when installing your distro or while choosing your distro. You can always change it once you've chosen.

KDE Plasma's infinitely customisable, yet also really user friendly, with a lot of incredible software included by default, including phone compatibility software similar to what you'll find in apple's ecosystem. XFCE's really lightweight and power efficient. GNOME's very macOS like by default, being a lot less customisable than KDE but really user friendly. They each have their own versions of software.

You should know what your distro's package manager is and how to use it, which is basically what you use to install updates and install and uninstall software. That's literally the only thing you'll need to use your terminal for, it's basically just a text based file manager which can run programs/software. That's basically it, just make sure to frequently update your system, they are voluntary unlike Windows updates and don't require reboots or crash your system, and you should be good.

Will my ability to play games be significantly affected compared to Windows?

Most if not all single player games will work without an issue on steam thanks to its integration with proton, if you use something else you can use lutris to fill in the gaps there.

Can I mod games as freely and as easily as I do on Windows?

I see no reason why you can't. Hopefully someone else can elaborate on that as I haven't done that in forever.

If a program has no Linux version, is it unusable, or are there workarounds?

It can be unusable. There could be workarounds but that would depend on how dirty you want your hands to get. You can install windows on a docker container and use that to fill in the blanks if needed. There would also be some linux alternatives of some apps which would be worth investigating and learning.

Can Linux run programs that rely on frameworks like .NET or other Windows-specific libraries?

I think dot net has been open sourced but you can get dot net apps using Mono.

How do OS updates work in Linux? Is there a "Linux Update" program like what Windows has?

You use the package manager, which varies based on linux distro/flavor. It's your best friend and you'll get 90% of your apps that way too. Upgrading depends on whether you are using a stable distro which is like say windows 7 and you'll have to upgrade to windows 8 (omg lol) you'll have to follow the procedure of your distro, It's usually well documented and should be fairly easy if your sticking to the flavor of Linux you're using. If you're using a rolling distro/flavor then you'll just keep your packages up to date regularly via the package manager. Be warned sometimes you'll have 300+ packages to upgrade so if internet is spotty may not be your thing. But it's a great way to ensure you're getting the most out of your new exotic hardware.

How does digital security work on Linux? Is it more vulnerable due to being open source? Is there integrated antivirus software, or will I have to source that myself?

Use clamav, make it watch the home directory /home as that's where you as the user have the privilege to write data to. Never run as root unless you're going to be extra careful. Also don't run scripts you don't understand or aren't well maintained in a public repo (at that point you as a newbie would be relying on community to determine if something is good or bad think of it as the upvote and downvote system but with more transparency)

Are GPU drivers reliable on Linux?

Yes, even the nvidia drivers are reliable. Just a pain as you'll have to reinstall the kernel module, the component that integrates the driver into your new kernel, after you upgrade kernel versions. Kernel is the thing that does all the low level handling of your devices.

Can Linux (in the case of a misconfiguration or serious failure) potentially damage hardware?

Most hardwares/processors now are designed with failsafes to throttle when there's not enough cooling. Please elaborate a little on this. You can break software but I think hardware should not be. Hopefully someone can elaborate as well.

And also, what distro might be best for me?

Linux mint, it is well documented, doesn't have the snaps that Ubuntu is pushing, its user friendly. Similarly fedora. You can try one of those immutable distros which may give you a more stable experience as it rolls back to a stable state on an update failure.

Can I mod games as freely and as easily as I do on Windows?

For the most part, yes. I've modded Skyrim, with SKSE and haven't run into any mods I couldn't add. Satisfactory has linux support for mods through the community-built mod launcher, so I haven't had any problems there. If you are comfortable copying files around, sometimes editing text files, uncompressing files, and other like tasks then you'll be fine. The only troubles I have had are running trainers that run alongside the game and connect to the running executable. There is one of the Resident Evil 2 remake I wasn't able to get going. I think there are methods to do this, I just haven't looked into them in detail yet.

For most things involving games in Linux, you need to have a small amount of tweaking skills, and that's it. You might have to copy a launch string into the Steam launch setup, or you might need to download a tweaked copy of Proton to get something running well (Glorious Eggroll builds). If you have those skills or can learn them, you'll be fine. It's kind of fun, too. If you don't have those skills or want to learn them, you'll be restricted to not being able to get the best experience when running some games and there will be the occasional game in your backlog that won't run at all without it.

Not trying to scare anyone off, but that's been my experience with Linux gaming. I'm comfortable enough on Linux that it hasn't been a problem, but some people might find it more of a hurdle to get over.

Can Linux run programs that rely on frameworks like .NET or other Windows-specific libraries?

So this one I thought I'd answer because I've done development in both NET framework and NET core and how it works is different for each (although things will usually work one way or another).

For .NET framework applications, if the program is compiled for windows (the .exe) you can usually run it with mono (you generally don't need wine, but there's some caveats that mean sometimes you should use wine). This will include programs with GUIs. If the NET framework app calls other windows programs it is best to run it via wine, you will need to install the net framework within wine, but there's a winetricks command for that. There are a few things that are generally niche things that do not work in linux net framework's mono though. By niche the one I can think of, is serial port events. Very annoyingly they all exist, so the program will run but the events will never trigger an action in the programs. Very annoying, but luckily very rare/niche stuff.

For .NET core, you can build directly to linux targets, and if the project you are working on does target NET core, then you can run the binary natively (note: you usually cannot build applications using forms to linux native binaries, for these you should run the windows exe with wine). You can also run the .exe files for this with wine and I've rarely had a problem with it.

Note that if you develop .NET applications, you won't be able to build anything that uses the standard forms GUI under linux. There are other UI frameworks out there you can use that are multi platform. For this reason, for the projects that do use windows forms, I have a VM with windows on that I boot up for this reason.

In short, if you're just running windows binaries, you will be generally fine with mono for framework and wine for core. For development "it's complicated".

Will my ability to play games be significantly affected compared to Windows?

A lot of stuff runs with windows emulation as if it's native. It's the same method the steam deck uses and so Valve actively do work to keep it working. The main problem is games with heavy anti-cheat.

Can I mod games as freely and as easily as I do on Windows?

Generally, yes. I think so.

If a program has no Linux version, is it unusable, or are there workarounds?

See above.

Can Linux run programs that rely on frameworks like .NET or other Windows-specific libraries?

There's .NET libraries for Linux, but things have to be recompiled to use them.

How do OS updates work in Linux? Is there a "Linux Update" program like what Windows has?

The distribution maintainer will issue updates on a regular basis. Update procedure is different for different distros, but all have a push-button update scheme. It's pretty solid these days.

How does digital security work on Linux? Is it more vulnerable due to being open source? Is there integrated antivirus software, or will I have to source that myself?

Keep your system up to date with security updates, and you'll tend to be fine. Smaller user base tends to mean that there's far less malware. Antivirus isn't necessary.

Obviously phishing scams don't care what OS you're on, so mind what you click.

Are GPU drivers reliable on Linux?

AMD ones are very solid.

Nvidia ones can be a pain from what I hear, but I don't buy green.

Can Linux (in the case of a misconfiguration or serious failure) potentially damage hardware?

No.

That said... You can always wipe a disk when you install an OS.

And also, what distro might be best for me?

Download a few Live-USB images and try them out. You don't need to install them to get a desktop and a browser up. You can see if there's any compatibility issues with your hardware.

Whichever works for you, go with it.

A lot of great questions. I think many details are already out there but I'll try to answer some to my best ability.

Answering the easier questions: Most games work check protondb.com for your specific games. There is a "Linux update" button on some popular mainstream linux distros - and it will never force you! Its also possible to update without rebooting for most updates (how great right?) No antivirus needed and it's more secure (but of course not invulnerable!)

Some of the other questions have a "It depends..up until a point" answers.

There are work arounds for non Linux programs....except for specific examples like some games. Valorant for example.

I'm not a modder or .NET expert but there's something called Wine which should help with that ...so answer is probably Yes-with caveats.

I'd recommend thinking about what are you "must work" deal breakers for work/hobbies (more specific than these more general questions) and considering if linux is for you. The distros that might work for you are Pop OS! and Linux Mint.

The neat thing is you can try these for free and hop around. I dual booted windows and Linux for a while before making the full time switch.

Will my ability to play games be significantly affected compared to Windows?

Many games with draconian anti cheat don't work. You can check that on https://areweanticheatyet.com/ and https://www.protondb.com/.

Can I mod games as freely and as easily as I do on Windows?

Do you mean creating or applying mods? Some of the tools might not run out of the box. But for most mods you actually just have to place the files in the correct folder.

If a program has no Linux version, is it unusable, or are there workarounds?

Can Linux run programs that rely on frameworks like .NET or other Windows-specific libraries?

Wine is the program used to run Windows software. It is used by Steam together with some other tools under the name Proton or Steam Play. It is best to use Wine with a helper frontend like Bottles. That creates an encapsulated Windows environment for every program and helps you in keeping potentially conflicting workarounds separate from each other.

But you can also run Wine standalone. Then every program will be installed to the same fake-Windows environment.

Missing libraries like .Net or the Visual C++ Runtime are actually the most common pitfall when trying to run Windows software on Linux. Bottles, Steam and other helpers will aid in their installation.

How do OS updates work in Linux? Is there a "Linux Update" program like what Windows has?

Every distribution has an application repository that also contains the system files. In general you update everything at once through one interface.

How does digital security work on Linux? Is it more vulnerable due to being open source? Is there integrated antivirus software, or will I have to source that myself?

Open source makes it more safe. You have more eyes on the software. And something that is only safe because nobody knows how it works isn't really safe.

Antivirus software's is not necessary. Neither is it necessary on Windows. It makes a system less secure because it opens up more possibilities of something going wrong. There have been enough cases of anti virus software with security issues on Windows. Or even anti virus software attacking important system files directly.

That said, if you still want to install a virus scanner there is ClamAV.

Are GPU drivers reliable on Linux

AMD and Intel greatly, because they are open source. They are integrated and don't need any configuration or installation.

Nvidia is worse. You have to install them yourself and sometimes they are unstable. But it's not worse than on Windows.

Can Linux (in the case of a misconfiguration or serious failure) potentially damage hardware?

Only if you really try and even then it's probably impossible. Hardware nowadays has many safeguards.

And also, what distro might be best for me?

If you have friends or family already using Linux you should install what they use.

I like OpenSUSE Tumbleweed.

My whole life with computers the fanbois du jour told me we had reached excellent usability. We’re talking GEOS, FVWM, the shit Sun and Digital Equipment Corp threw at us, up until Windows 10 and KDE or what have you: there will always come a point when you need or want to have a look under the hood. And there things can be alien, overly complex and very inconsistent and undocumented. That is the path every real user will walk one day, and it’s not pretty. Best of luck on your journeys!
