When i start up a game, it just lags extremely bad for the duration of when i quit but only when moving my character the lag happens, other times when i start up the game and play it is perfectly smooth with little to no lag. It is not my specs i think because I've ran the same game perfectly smooth but it just acts up at times. Sometimes restarting my computer fixes it, sometimes not. I think my 100% disk usage has something to do with it. When i quit the game, i notice i can't click anything such as chrome because it is so slow and laggy, when i manage to open task manager after a couple of minutes, my disk usage is at 100% then drops immediately once task manager finally loads open. No other forums helped. Help me please.
