If your not playing online, you could shut avg down before you play ( in fact shut down every thing you don't need) See if it makes a difference. I found that when I went back to medal of honor airborne after cod4 I thought the game was slow and camera angle rather odd, it was just that I got used to the way cod4 did things.
I got into the habit of just minimising the browser while playing games and that caused no problems but when I was doing that with avg8,things got a bit jerky. The advice given has helped. I now close the browser and alls well.
