Steam using CPU to process vulkan shaders instead of GPU? (kbin.social)

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?

Valve created the ACO shader compiler, but it's only for AMD GPUs.

ACO runs on the CPU.

The output it produces is for AMD GPUs.

Oh, my bad. I think I misremembered.
