Something like not enough memory?
Ok, i've got Core Due Duo 1.87Ghz, Geforce 9400 GT, 4GB of nice Ram, a lot of disk space, and stuff. I NEVER played in my life a non-laggy game, my simspeed is around 4-5 with wathever graphic config i set. PC usage says 100%, but 17%-20% is from ZONE ALARM ???, but the longer the game gets the higher i get it laggy, even the sound starts to be like "nn--nnn-nnnoo---oooo mm----mmm--oorree mm--mmmaaa----aaa--nna"!!!!
Why does this happen?
Reinstalled everything on this hd about 2 weeks ago, no viruses, no other.
I need a bigger cpu?
