Hello. I just updated my windows 7 32-bit version to windows 7 64-bit, The problem is when i try to open a game it lags [especially MTA:SA] so i realised that i have waited for 1-3 hrs then i tried to open the game and suddenly the game is not lagging. So do i have to wait for like 3 hrs to play the game normally? I need a solution to fix this.
