How do you cope with shader processing? (sh.itjust.works)

It feels like I mine bitcoins for our Great Daddy Gaben every other update, setting my CPU at 100% for a long time.

I know it makes difference (to skipping it and eating lags), it works, but how it doesn't use previous literal gigabytes of generated shaders, starting from 0% every time? Why it takes so much time?

I feel like I'm a dumbass and I miss something obvious. Or I just feel like I'm alone with it? Do you guys all deal with it?

Am sitting at 66% percents, my PC heats like it renders video in Premiere, just to let me play the game I've played yesterday again. Guess all my recycling and replanting routine can fuck right off with that power consumption. Sorry, nature, I tried.

But anyway if you are tired of it or knows some tricks, write what's on your mind.

Ultimately this is what it's running in the background: https://github.com/ValveSoftware/Fossilize

The idea is to make sure your graphics card shader cache is full with everything the game may use at some point, enabling smoother play and less hitching.

I think on NVIDIA, the cache ain't that big by default so it may be recompiling everything from scratch, whereas it's less noticeable on AMD systems because it's already compiled it so only compiles what's changed/new.

This issue suggests it's currently pretty broken on NVIDIA right now: https://github.com/ValveSoftware/steam-for-linux/issues/9803

Didn't know they have a github account. Thanks for pasting these links. I'd study this Q more while another reshadering is going on.

What isn't broken with Nvidia? :b
