Just tried it again and changed some settings. Ran everything on "LOW" and set gametime.maxvariablefps 0 so it wasn't limiting my FPS at all. My FPS was around anywhere from 180 all the way down to 74. It fluctuated violently between those two points. I played the game without the hack running for a while and the lag and input lag were both gone. Before I was playing with the hack active and with FPS capped to 60 and it always stayed at 60 with no drops whatsoever. So the lag must be coming from somewhere. If it isn't from the game directly it has to be from windows resources being nuked due to the overlay. Also the lag seems to get worse overtime which is what leads me to believe it has to do something with the overlay eating system resources in the background causing some sort of leak or something. I'm not 100% sure. But that is my findings.
