mismatched OptiX versions, found 6.1.1 expected 6.0.0

Hi, I am getting this warning in Houdini

mismatched OptiX versions, found 6.1.1 expected 6.0.0

with the following

NVIDIA Driver 430.14

Houdini 17.5.229

HtoA htoa-4.0.2_r236e192_houdini-17.5.229

It is my understanding that the newer OptiX version it is loading is bundled with the NVIDIA driver?

Does anybody know what is the latest NVIDIA driver I can run that will use OptiX 6.0.0?

We have some bugs in our renders and I would like to rule out the mismatched OptiX versions

The Optix versions are compatible, but if you want to go back to Optix 6.0, you need a driver from before R430.
