Hello ,
Thank you for posting in the community and wanted to know if you tried the Tdr Delay workaround? If you tried it and are still having this problem try increasing it from 15 to 30 and make sure to restart the computer after making any changes in the registry.

If you are on a lop top the Studio Driver is the right one and if you are on a desktop the Game ready driver might be better.
If this still did not help, please contact us directly here so we can investigate further with you:
