Description
Describe the bug
- Once configured, Fallout New Vegas has abnormally poor performance compared to other games. On an i7 12700k and RTX 4090, I'm only getting 17-18 FPS. The DXVK hud reports 100% GPU utilization, but in actuality it's closer to 30%.

Research direction
Start by reproducing the FPS regression with Fallout New Vegas launched through nvse_loader, then compare the attached d3d9.log, FalloutNV_d3d9.log, NvRemixBridge.log, and rtx.zip data. Check whether repeated restarts and alt-tab change the result; done means the cause is identified and performance is consistently restored without the reported alt-tab regressions.
