i was using driver 17.2.1 and the game was working good
when i tried to update to 17.7 the latest version the game was very slow and the sound go and back every minute and there were many lags in the game
what should i do ?
Revert to the driver that works for you. Use Device Manager. It is not necessary to install every "update" that becomes available. Only do so after you have read the "Read Me". If there is no FIX for a problem you are having with your card or application...there is no reason to install it.
