Having all sorts of crash drama here since I've upgraded to this driver, and Rocky9.4.

when you say "crash", what do you mean?
- all of houdini crashes?
- or just the optix device fails?

any crashlogs or error messages?

Is this an Optix-only issue?
For example, if you render using only the EmbreeCPU device, do the artifacts go away?
envvar KARMA_XPU_DISABLE_OPTIX_DEVICE=1
What is your hardware setup? Do you have 1 GPU? or 2? Driver version?

FYI, here is another use also with motionblur issues, but they stopped communicating before we were able to solve the issue.

Can you please repost this error? using inline code formatting? (or even a screenshot will do)
The forum strips out anything in square brackets, meaning the actual error has been removed from the text :/

thanks
