Hello @bojogon7, on the Steam client side, this isn't something that Steam should be handling directly. On Proton's side, only one render path for each graphics API is considered supported and older builds of DXVK, third party builds of DXVK, and wine's DirectX to OpenGL render path are not considered supported.
This request is a non-starter for the Steam client and mainline Proton.
Thanks for reply @kisak-valve, but wouldn't that mean that steam is only supported on systems with vulkan 1.4 and up?
Nothing extracted yet.
Problem description
Depending on GPU you can have various performance impact by using incorrect translation layer.
Feature description
Based on GPU choose recommended translation layer.
When GPU supports:
Vulkan 1.4 and up = DXVK 3.0+
Vulkan 1.3 = DXVK 2.7.1
Vulkan 1.1 to 1.2 = DXVK-Sarek or DXVK 1.10.3
OpenGL (only) = WineD3D
