Hey guys, been working on this issue for a long time now and just figured out that display fusion was the issue. When moving my mouse in games I will get extreme stutters/fps drops caused by display fusion eating up the CPU. The higher the polling rate on the mouse, the worse this stuttering becomes. At 500hz, the issue is almost fixed, anything above 1000hz it becomes unplayable. I've heard that disabling application hooks fixes the issue, but that disables the main reason I use display fusion.
