At 1920 no problem, smooth and loads about 20% on gpu decoding, 85-90 fps.
From 2160 and over, grey artifacts, stutter and loads 0% on gpu decoding.
Why?
Rx 470 8gb
i3-6100
I tried with microsoft extension and lav filters, but nothing changes... mp4 codec appears non chechable on lav config, may be realitioned?
