Hello,

I just downloaded ParaView-5.9.0-MPI-Linux-Python3.8-64bit, when I try to enable ray-tracing with OptiX I get the following error:

VisRTX 0.1.6, using devices:  
0: Quadro M620 (Total: 2.1 GB, Available: 2.1 GB)  
terminate called after throwing an instance of ‘VisRTX::Exception’  
what(): Failed to generate OptiX program “Exception” from PTX: Parse error (Details: Function “RTresult \_rtProgramCreateFromPTXString(RTcontext, const char\*, const char\*, RTprogram\_api\*\*)” caught exception: The supplied PTX requires at least one device with SM 52 or greater.)

You can see that my GPU is Quadro M620 which on the nvidia website has a computing capability of 5.2 ([https://developer.nvidia.com/cuda-gpus](https://developer.nvidia.com/cuda-gpus)) so I guess it has the SM 52 requirement, but why do I get this error?

Thank you in advance.

EDIT: OptiX works fine with ParaView-5.8.1-MPI-Linux-Python3.7-64bit
