If it were that simple I would have solved it already. It’s a really odd occurance where all programs that are ‘affected’ by mouse movement spike in CPU levels. When I stop moving the mouse, all programs immediately stop using CPU and general CPU usage drops to 1-0% while when spinning the mouse around it’s up to at least 20-30% total CPU usage, which isn’t normal. Explorer.exe, dwm.exe, csrss.exe and the system process (PID 4) seem to be mostly affected by this problem as they show the highest CPU usage when wildly spinning the mouse. Other programs join in but only spike up to max 1% usage. I’ve barely got any programs running in the background. This is a clean Windows 10 installation with only 4-5 games installed or so, nothing else. The problem is that I can’t blame the usage on one specific process since it seems like nearly all processes are affected by mouse movement. Even GPU acts up when spinning the mouse, showing up to 20% GPU usage for DWM.exe and csrss.exe when moving it.
Few weeks back I didn’t have this problem at all, even when I used to run OW on an i5 3550p with 8gigs of ram and a GTX 760. I’ve tried going back to the old setup before but it strangely that didn’t fix the problem. I have even replaced my HDD and PSU but made no difference. I’ve tried changing up in-game graphics settings, Nvidia graphic settings, messing with Windows settings, BIOS settings after doing a LOT of research online, but the problem persists. The issue exists on desktop as welI as in any game I play, not just Overwatch. I am getting really desperate at this point.
