Description

Proton: Proton 8.0-3, Proton Experimental, GE-Proton 8-9

Distro: Arch Linux, 6.4.6-zen

GPU: Geforce RTX 3080, 535.86.05

Platform: X11

Launch options: DXVK_FILTER_DEVICE_NAME="NVIDIA GeForce RTX 3080" PROTON_ENABLE_NVAPI=1 PROTON_HIDE_NVIDIA_GPU=0 VKD3D_CONFIG=dxr11,dxr VKD3D_FEATURE_LEVEL=12_2 mangohud PROTON_LOG=1 %command%

The game completely freezes after the Playstation intro and if I don't kill the process fast enough the entire desktop (Plasma 5.27) hangs as well.
Running dmesg I get this error during the crash: NVRM: Xid (PCI:0000:0b:00): 109, pid=30603, name=RiftApart.exe, Ch 00000016, errorString CTX SWITCH TIMEOUT, Info 0x1c00c

And in the Proton log I get this: warn:vkd3d-proton:d3d12_command_list_IASetIndexBuffer: Invalid index format 0. This will map to R16_UINT to match observed driver behavior.

Research direction

No source file or test is identified. Start by reproducing the freeze with the listed Proton versions and launch options, then compare dmesg's NVIDIA Xid 109 with the Proton log's vkd3d-proton warning. Done would require identifying and resolving the post-intro freeze without causing the desktop hang.
