Hi,
Getting wierd results with RTX4090 and Karma XPU. Nvidia Studio Drivers 551.23 (latest). Houdini 20.0.590, clean install.
5995wx + 4090 gives these (circled) artifacts:
5995wx alone (using KARMA_XPU_DISABLE_OPTIX_DEVICE in houdini.env to disable GPU) gives no artifacts:
Test system using 2080Ti and 10900k also gives no artifacts (using same nvidia drivers and Houdini version, clean install):
What could be causing this and how can it be fixed?
