Issue Description (Required):

After Darktide 1.13, I’ve experienced multiple issues which all seem related to DX12 renderer:

  • Repeated 250–400 ms stalls in Window::update and RI::wait_for_fence. These stalls caused fixed-frame recovery messages and apparent lag/rubber-banding.
  • First fatal incident: texture-streaming tile unmapping blocked the renderer for 16.56 seconds, with NVIDIA’s driver in the stack.
  • Second fatal incident: D3D12QueuesFrameFence::signal_fences timed out after more than 15 seconds.

I have the RTX 5070 Ti Laptop GPU, driver 595.79, DX12, and DirectStorage. Neither incident contained Lua/mod errors or indicated RAM/VRAM exhaustion. The console logs for the first two issues have been rotated out. Attached the one for the last crash.
