Found out what my problem is today, its punk buster!!!!!
Today I went on multiple servers that did not have punk buster and played fine. No lock up or lag, fps stayed steady at 60 with no jumps, played for about one hour.My ping was 150 on one server and played fine. The graphics are awsome with my new card !!!!!!
Now if I go on a server with punk buster the lock up happens and fps goes to crap, if I go to a server not running punk buster after this happens it also runs like crap until I re-boot. Then I can play Non punk buster servers with no problem again.
It has to be punk buster , they came out with their update and that is when I started having this problem.Today was the first time I tried to play on a non punk buster server after a re- boot, so I thought the non punk buster servers were giving me the same probs. (duh).So I guess the question is now that I know what the problem is how do I fix it?
