So the only problem is you'd have to update every VM over time to get security patches, this is mainly a problem if you're on limited internet(like me). Im capped at 100gb a month and my download speed is almost always less than 1mb/sec.

Windows has a feature that if one system on your network is updated, other systems on the network can download locally from that one and save your data, which is wonderful. But you still need to update Nvidia drivers for each VM, and update games, etc. You can connect a hard drive(virtual or physical) to multiple VMs, but only run VMs with a common hard drive one at a time.

And mind you this isn't to save compatibly, for me once it works it works. I just like to keep security patches updated because I download a lot of sketchy programs lol.

Latency is non-existent. I use a program called lookingglass, which allocates like 32mb of GPU memory to be dedicated to passing frames between the VM and the host. Or non-existent for my level of perception. If you're Spidey senses tingle more easily you can pass through a secondary keyboard and mouse and just literally have two screens two keyboards two mice one box. It would have the same latency as bare metal. And even have two people play multiplayer games together off of one box if you have the horsepower.
