watchdog aborts the process:
LowLevelFatalError [File:Unknown] [Line: 1209]
GameThread timed out waiting for RenderThread after 120.00 secs
On a given boot it either freezes or works every launch. When it launches it's stable for hours.
Rebooting most of the time fixes the freeze. Restarting Steam does not. After using PC for a while, it may stop launching again.
From my understanding it is a race between DXVK and D3D12.
Launching with %command% -d3d11 as steam command fixes the issue.
Details
Thread dump taken while frozen (/proc/<pid>/task/*/wchan): every thread is in
a futex wait, nothing spinning. Both driver thread sets are live at the same
time — vkd3d_queue / vkd3d_fence (x3 each) and vkd3d-swapchain, alongside dxvk-submit / dxvk-queue / dxvk-cs. The game decodes the intro movies via
Media Foundation into D3D11 textures shared into the D3D12 renderer, so this
looks like the interop handoff.
vkd3d logs this on both device creations:
d3d12_device_create_vkd3d_queues: Could not allocate an out of band queue
for queue family 2. All out of band work will happen on the in band queue.
(same for queue family 3)
Timeline from the attached log — the RenderThread's last check-in works out to
~18683.4 (18803.462 minus 120s), which lands right on the last vkd3d activity:
18683.786 vkd3d_pipeline_library_disk_thread_main: Flushing disk cache

Nothing else is logged across the dead window.
This did not help: VKD3D_CONFIG=single_queue, PROTON_DISABLE_NVAPI=1, windowed
mode, single monitor, disabling ForceCompositionPipeline. No Xid errors in
dmesg — the GPU is not hanging.
