Does VKD3D_DISABLE_EXTENSIONS=VK_NV_optical_flow VKD3D_CONFIG=nodxr work around it?
Seems like a common issue with games that recently updated their DLSS, unfortunately there doesn't seem to be anything we can actually do about that from our end since the failure happens as soon as CUDA libraries are loaded by the driver.
Does
VKD3D_DISABLE_EXTENSIONS=VK_NV_optical_flow VKD3D_CONFIG=nodxrwork around it?
YES it WORKS :D THNX
I have attempted to reproduce this with a couple of different configs but have not had any luck. @KayCe75 are you still able to reproduce this issue with the current build of the game? If you can it may help to reproduce the issue and then run the nvidia-bug-report.sh script. Once you have done that you can upload the resulting report to this issue.

Description:
After a Pax Dei game update (build 5133.167573 / release_43, 2026-02-11), the game fails to start with D3D12CreateDevice failed with code 0x80004005. The game previously worked fine with the
same driver and VKD3D version.
