FEAR - stuttering

[Mfr]

I have just bought a 3800 X2 and completed a fresh xp pro install. I then put fear on and patched it, the game was playing perfect on previous settup (3700SD, 1GB corsair 4400, bfg NF4 mobo, bfg7800gt. Only change 3800X2) The game was stuttering badly and when I looked at the mem usage their was 768MB free but for sum reason fear was using the page file and cahing the entire game. have googled but nada so for, any help would be great. btw think this may be happening in bf2 aswell.

Hello, thanks for the replies, yeah I thought about the texture settings but its the same when it worked perfectly on my 3700SD, the page file is set to the win default 1536mb for system of 1gb. I also installed the win dualcore hotfix and reg edit. bf2 works now, probably due to the overclock (2600Mhz 10X260, prime stable) It has me beat as i've never seen a app use the page file when there is so much free system ram avalible. I bought the 3800X2 as I destroyed my SD by taking the shim of with a penknife doh.... oh and its a brand new install.
