Reworked some of my overwatch configurations, had this guy 4k rated mcree go through it with me. Realized i had my FPS limited based on user display, aka 70 fps.. guys like you need at least 150 for hit scanning, so set it to custom 300 and jumped up to 150. I usually play in windowed mode, guy had me go to full screen, jumped to 230 fps. set most things to low quality or off, render scale at 75% and resolution from 1920 to 1280 and I'm capping at 300 fps. Went to 800 dpi, 6 ticks out of 11 ticks on the windows control panel sensitivity, then 10 ingame sensitivity (he had it at 5 but i couldnt do a 360 from one side of my mousepad to the other so I upped it). Aiming seems lot easier with mcree and soldier than before.
Interesting stuff though, to think I was missing out on some of this, my mouse movement is hella smoother now.
Only annoying issue is I have EQ minimized and when I go full screen overwatch, I get a render error on EQ and it crashes. guess I'll have to do offline bazaar mode.
