Now THAT's confusing.
hmm im only get 66 FPS regardless how many time i restart, just a note 400 fps sounds too quick, gpu encoding doesnt give same quality as cpu, so id be happy for gpu to be spitting out the best quality it can do "--preset quality" even if that means less fps, im sure gpu at max quality will be a lot quicker than cpu, will be nice to have the option of HW excelearion, will you be including 264 hw exceleration also ?

in using a RTX 2070 Super
