Flickering/missing geometry in RE engine games

NVIDIA Open GPU Kernel Modules Version

590.48.01

Please confirm this issue does not happen with the proprietary driver (of the same version). This issue tracker is only for bugs specific to the open kernel driver.

• I confirm that this does not happen with the proprietary driver package.

Describe the bug

As first reported in this issue on the Proton tracker with RTX 5000, there's a problem with missing or flickering geometry in the Monster Hunter Stories 3 demo. I could reproduce the same issue on RTX 3070 in MHS3 and also with GTX 1660 Ti in MHS3, the Pragmata demo and Resident Evil Requiem.

On RTX 3070 I tested both 590.48.01 and 580.94.17 with the open kernel module in MHS3. On GTX 1660 Ti I could only test the 590 driver with the open module. I have not been able to reproduce this issue on GTX 1660 Ti with the proprietary module.

To Reproduce

I've been most easily able to reproduce this on the GTX 1660 Ti on the title screen in the Pragmata demo. In MHS3 it happens most quickly inside Azuria castle a few minutes into the demo. In Resident Evil Requiem it also happens within a few minutes after starting the game.

The common factor seems to be vsync disabled, low preset and 1080p to get a high framerate. On the RTX 3070 it's been more difficult to reproduce, so I haven't been able to reproduce the issue on the title screen in Pragmata there, but it still happens occasionally in MHS3.

More Info

I haven't been able to capture this issue in RenderDoc, as any capture will replay normally afterwards. Adding extra barriers (graphics, pre-raster, pre-compute, post-compute) in vkd3d-proton also had no effect. VKD3D_CONFIG=breadcrumbs_sync also had no effect.

Start with nvidia-bug-report.log.gz and reproduce the flickering or missing geometry under the listed conditions in the Pragmata, Monster Hunter Stories 3, or Resident Evil Requiem demos. Compare behavior with the proprietary module and use the existing RenderDoc and vkd3d-proton observations as context. Done means identifying and correcting the open-kernel-driver issue, then confirming the affected games render reliably.
