I was a bit surprised today when I was playing Crysis for about an hour and my FPS started dropping to 1-2 quite often and became a bit un-playable. I alt-tabbed to check my temps on my video card and all, and yea, surprise, I had no ram left (this time with no firefox or utorrent open). had to restart the game. Still, sometimes I don't really understand why in the high demanding games they freeze for about a second sometimes. Can it be programs like kaspersky or something? Also I benchmarked GRID following the details of a website who benchmarked a few cards raging from GTX 295 to gt 7600. Their HD4870 averaged 86 FPS while I only averaged 74 FPS. The only difference was their CPU who was around 3.2 GHZ. Are some cards of the same type simply a bit slower than others with the same specs?
