Most likely main thread limited (or other CPU limit)... You can check if you turn on dev mode and enable the frame counter - it'll tell you the limiting factor. CPU being at 65% ultimately means nothing and it can still be your limiting factor, it's not really as simple as when looking at GPU utilisation.
Thanks. I have used that before. CPU utilisation maxes out when panning quickly with opentrack.
Do you think going from a 4790k/1866 to a 5800x/3600mhz would give me a decent improvement?
