  @NeoTheFox Following up as promised: I can now confirm stability with `VKD3D_CONFIG=single_queue`. Three sessions since setting it (July 18, 20 and 21, roughly 2 hours of play in total) — zero GPU hangs, clean exits ever...

  Has anyone tried Proton Experimental Bleeding Edge? I've had that resolve issues that even the latest GE or Cachy Proton couldn't solve!
