I didn't know what section this would belong, so I decided that since games rely mostly on GPU power I would put it here. I was playing Black Ops the other day and it was perfectly smooth. (I am using a hd6850 820/1100 core/shader) Today when I was playing the game would start at around 60 FPS and then randomly sink down to 30 FPS. It was on zombie mode on the first map, normally when I look out a window or walk by the teleporter core. I am using an AMD Athlon II x3 440 @ 3.3Ghz, 4Gb 800Mhz RAM, and a hd6850 820/1100. I am playing at 1280x1024 res. If you need anymore information I would be happy to provide it.
P.S. It feels like I have a bad connection when I play when it jumps from 60 to 30 FPS, but I am not playing online, just solo.
THE URGE TO KNOW WHAT WAS WRONG WITH MY COMPUTER WAS TOO STRONG... so... I got mad and broke it... Just kidding! I checked and the V-sync was indeed on. Thank you for the help. I Am not going to try it to see the performance, because like I said it is getting late. So I will tell you tomorrow.
