If I run the valley benchmark by itself I get 50 fps at 1280 by 720 but there is a bit of stuttering. Now if I run a rendering line art conversion software such as Linify (online software that converts images to line art) Valley runs smooth as silk with absolutely no stuttering. You do take a 10 fps loss in Valley though. 40 fps. This make me wonder if the Apu is shifting speed up and down but the art program forces all 8 threads to full speed? Linify uses 80 90 percent cpu.....
