Club 3D CAC-1085 with…
- nVidia Game Ready Driver 457.30 – Nov 09, 2020 – LIMITED.
- nVidia Game Ready Driver 457.09 – Oct 29, 2020 – LIMITED.
- nVidia Game Ready Driver 456.71 – Oct 09, 2020 – WORKING.
The option “Perform a clean installation” was selected each time.
In the nVidia Game Ready Driver versions after 456.71, the resolutions and color depths and frame rates are limited. Rolling back to 456.71 reverted the limitations. Further description of the limitations:
The resolution 4k (3840×2160) is limited to 60 Hz, and can only be increased to 120 Hz by creating a custom resolution profile. In that case, the option to go above 8 bit-color with RGB or YCbCr444 rather than being able to select 12-bit color, is also lost.
I expect working with Club 3D support and nVidia support on this issue will be the best way to resolve this.
