Found a small stutter which was visible during vsync inside the reshade.me statistics graph, a big spike every second or so. I was going crazy, because microstutter annoys me in racing games and vsync is always nicer for fullscreen windowed.
After flashing 480 back, same thing happened. I guess the new driver changed something but I figured out a fix after seeing how closing hwinfo64 stopped it!
Right click hwinfo, choose settings and go to this tab and try this:
If it doesnt fix it, try checking more of them, but keep 0 unchecked because that was the one that would stop my rx480 reporting on hwinfi:
Alternately you can just keep i2c via ADL unchecked, but for my card I lose temperature/power and a few other readings.Edited by robnitro - 4/28/17 at 10:16pm
