Symptoms

Getting an underloaded CPU & GPU (both ~25%), which results in 10-20 fps with absolutely any graphics settings, no difference.
Other games work flawlessly on my setup out of the box.

I've tried:

• clean game reinstall, including pfx
• installing the latest mesa-git
• installing amdonly-gaming-* packages
• gamemode & gamescope
• diff schedulers
• updating & resetting bios
• disabling iGPU
• a ton of ENV's, only noticeable one is the "VKD3D_CONFIG=nodxr", +5-10fps
• gave up and installed Windows as a dual-boot (sad one), resulting in ~90fps with "very high" (maxed out) graphics preset w/o any FSR / frame-gen, native FHD resolution.

No effect env's:
SteamDeck=1
VKD3D_DISABLE_EXTENSIONS=VK_EXT_descriptor_buffer
ENABLE_GAMESCOPE_WSI=1
VKD3D_FEATURE_LEVEL=12_2 / 12_1 / 12_0
