RTX2070 SUPER (Driver Version: 457.30) returns VideoCodec version 8.1

I’m trying to use VideoCodec 11.0 API on RTX 2070 super + Driver 457.30.

The ReadMe’s system requirement is “Windows: Driver version 456.71 or higher”.

However in the function NvEncoder::LoadNvEncApi(), the driver returns 129 at the line, NVENC_API_CALL(NvEncodeAPIGetMaxSupportedVersion(&version));

129 is the number for VideoCodec version 8.1, isn’t it?

Should I use VideoCodec 8.1 on RTX 2070 SUPER (TU104)?

Hi.
Are there more details to the reproduction setup than what is already mentioned? Can you confirm driver installation was correct and there is no other driver dll being used in the system than the one installed by 457.30 driver?

Thanks.

The folloing is the text from “NVIDIA control panel system information”.
