Well, recently i've built a new PC, it has 8GB ram, i5 3570k quad core processor, and a GTX 660 GPU.
A big majority of the time playing Arma 2 OA, using fraps to watch FPS. It will be up around the 60 range and drop wayyy down below 10 and freeze. It happens maybe every 5 seconds for around 1 second each time. Regardless if I have the settings all the way down or not. It is the same way in single player campaign, unless i'm in the Armory section trying out weapons and such. I have looked on many other forums and have done what they do to increase performance and such, but obviously it hasn't worked any. All my software temps range at about 60C on full load, which I don't believe to be all that hot. I have reinstalled the game on two different HDDs with the same out come as well.
Any answers will be appreciated, thank you!
