gVisor does support NVIDIA GPUs and some Vulkan ioctls are supported. If you want to run games in it and find incompatibilities, patches welcome :) Agents are great at completing gVisor's nvproxy ioctls nowadays.
I've personally run Unreal Tournament 2004 at 40fps on my laptop, with pure software-rendered OpenGL a few years ago (GPU support wasn't there at the time).
