Have you updated to the latest NVIDIA graphics drivers?

I have updated to the latest version

Can you tell me how to delete C4Dto completely？ Because after I reinstalled c4dto, the settings are the same as before.

It's not C4DtoA that's the problem, it's the driver install.

Unless you also have an older version of C4DtoA, which you can remove using Windows Control Panel.
