My Crysis Warhead Performance fixed

Wow, well, have a e6420 @3.4 ghz 9800 gtx over clocked to like 780 and 2100 i think and 2gb of ddr2 800 with vista 32bit. anyway, game ran like crap, in the jungle areas, or the outdoor train stages, it was sooo laggy could not play the game, i had to put it to mainstream, but i had an extra 1gb of ddr 1066 that i had around, so i just poped that in, just to have more ram, i didnt care that its not matching, and it wont be in dual channel. The extra ram did wonders to crysis, i can now put the game with everything on enthusiast and its playable, everything on gamer is going on 30-35. Before it was like 10-15. Soo if anyone is having similar problems, that they have decent hardware and horrible fps in crysis, then u might want to look into getting more ram. Also the game kept crashing with the 178.13 drivers, so i installed the cuda drivers, which i think is like 177.93? and now the game hasnt crashed since.
