Hey all, I have a RTX 3060 and a Ryzen 5600G and I’m on Ubuntu 22.04. Since Steam has shader pre-processing on Linux I thought I’d ask on a Linux gaming community about this. I noticed that when Steam processes Vulkan shaders, it uses the CPU (my CPU heats up a lot and the process manager shows CPU being used while GPU is not used at all). Is there a way to make Steam use the GPU to process Vulkan shaders instead, or am I wrong and Vulkan shaders have to be processed on CPU? I’d presume that things like shaders would process faster on a GPU (it takes a long time for them to process on the CPU). Anyone know anything about this?
You can turn off shader precompilation in Steam, but that’s not tied to the distro.
If you have it off, you won’t need to have the pass run before starting a game, but then the problem that it was aimed at solving comes up – shader compilation has to happen during gameplay, and this can cause momentary hiccups when a shader is used for the first time.
Steam can optionally do background shader compilation, in which case it’ll run at some point after updating a game, rather than right before a game runs. That may or may not be what one wants.
