Hello i used to be able to play battlefield 3 at a steady 50+ frames with a amd radeon hd 7770 i noticed last week as i would start playing multi/single player the frames would dip down to 8 after a few minutes i used windows defender to scan for a virus Nothing came up so i updated my driver defraged my hardware cleaned the gpu with a can of air the temp whilst gaming is about 40-60 playing at 1440x900 sometimes the audio will cut out when the frames drop? dont know what that could be but sometimes like i said it can be at 83 frames on low go to 30 then to 8 and repeat or stay at 8
