I can indeed confirm that the env works! (KARMA_XPU_OPTIX_FORCE_GAS_TRACE=1) I've had multiple issues lately w an unstable GPU - Linux which is now running smoothly.. Thanks!

Great to hear this worked for you.
The latest drivers contain a fix so that you don't have to do this anymore.

Do i also need to update Houdini version to take effects?

Hi guys, I am still getting this error in 20.0.653 and driver 552.22.
Has this not been resolved?

Apologies. I did a clean driver reinstall through geforce experience and it seems to have resolved the issue thanks!

Specs:
Windows 10
AMD Ryzen Threadripper Pro 5975WX
128 GB Ram
Nvidia GeForce RTX 4090
NVIDIA Studio Driver 577.00

Tested same file on another PC with same specs but Windows 11. Getting same errors.

Errors:
KarmaXPU: Unable to create CUDA context for device 0 (maybe old driver? requires 535+)
KarmaXPU: device Type:Optix ID:0 has registered a critical error , so will now stop functioning. Future error messages will be suppressed

Is there any list of supported drivers that one should install to avoid these errors? Thanks.
