Sorry about that. I don’t know the exact display driver versions which would have received the fix. It might not have made it into that specific R530 release, yet
Yes, the printf issue is known and will be solved in a future driver release.
Until then please set the environment variable OPTIX_FORCE_DEPRECATED_LAUNCHER=1 mentioned inside the OptiX release notes for debugging and profiling purposes.
