Hans-Kristian Arntzen with Valve has just released VKD3D-Proton 2.14.1 as this Direct3D 12 over Vulkan implementation.

This point release just brings a few fixes to this key library used by Valve's Steam Play (Proton) for enjoying Windows D3D12 games on Linux:

"Fix a crash on start-up which affected GPUs without sparse support. E.g. Intel iGPU or Turnip.

Crash could happen even if that GPU was the secondary GPU on the system.

Fix a memory allocation issue affecting NVK.

Fix a CPU performance regression issue affecting Horizon Zero Dawn Remastered on NVIDIA GPUs.

This fix might improve CPU performance in other games too, but unverified.

Not a regression fix, but add a no_upload_hvv workaround for Arma Reforger to workaround weird asset loading behavior."

Those building VKD3D-Proton packages from source can grab the new update via [1]GitHub .
