I've been having problems for some time now and have tried something different. I was having trouble with choppy gameplay and lowered fps in CS:GO. i7 4790/gtx 970. I have my fps capped at 300 and get 270 fps and very unstable. Today I tried not limiting my fps and was getting 400-500 fps. Menu is capped at 119 and is bouncing around at 110. Why would my fps be lower that what it is capped at if I can get 500? It is still very unplayable with high fps..
