Thanks, am just testing the 4080 Super now to see how well it works and it seems to me it is CPU limited in my system. It would perform better with faster CPU. On other hand, when encoding mkv in StaxRip using NVEncC encoder, there is no difference from RTX3070. It gives me the same 50FPS ish (no CPU limited in this case)
btw, here is my setup with 4070 Video AI 4.0.X - User Benchmarking Results - #225 by testthewest20
EDIT: there isnt studio driver for W11 for 4080 Super in the moment - I tend to prefer them over game ready drivers.
