Install Nvidia Vulkan Beta Dev Drivers?

No problem I’m glad it works for you. As i say I’m not really much into gaming. I just try to help users get the Nvidia drivers installed and working.

AFAIK this is the proper way to set up graphics pipeline library:

  1. Install nvidia-all and reboot
  2. Either disable Steam shader cache or opt in to Steam Beta
  3. Use Proton Experimental

That would be installing only the precompiled driver module for the linux kernel.

You need other packages for full support. I’d suggest the following combination: nvidia-vulkan-dkms nvidia-vulkan-utils lib32-nvidia-vulkan-utils.

The DKMS package means the driver module will work across all kernels, and the 32-bit library is needed for many Steam games.
