Can this system max MW2?

Anyone? I'm still at a loss here as to why this preforms so badly.

Just 1 HD 4850 them alone should max out MW2 at that resolution.

If the above suggestions do not fix it, try removing one of the cards.

Also, what is your PSU?

I'm running Vista64, C2Q@ 3.2, OC HD4850 and running all high 2xAA and 1680x1050 and getting some lag and stuttering in MW2 as well. This computer runs COD4 smooth as butter. Maybe just has some issues cause its new, maybe a patch or new ATI driver will fix it soon.

Yeah theres a few spots where it completely stutters out and I cant really even move much, but for the most part its fine.

by the way it can also be harddrive related... there are some places where even my 3 seagate 500Gbs 7200.12 have enough bandwidth for a smoth loading... when this happens the game laggs a bit... in my case it isnt much, but if your harddrive os older it might be more significant

Well its a WD Black only a couple months old. It runs COD4 at 100fps so I dont think its that.
Some spots It's hard to even fight because I'm in like slow motion, lol, usually when theres a big fight scene in a large area with lots of smoke and stuff.
Downloading catalyst 9.11 now, it just came out yesterday.

i had big stuttering frame drop in SP when there are smoke or burning.

some in MP ,thank god only couple of maps stutter (nothing unplayable but damn annoying especialy in Mp cmon)

and it feels like its not giving the performance that it should,
its very bad comparade to cod4:mw i had STABLE 100-125 fps there.

the game uses all the cores nicely and so does the GPU the utilization is around 90-100%

my rig is phenom at 3.1 ghz (4cores)
ATi 4870 / 512
4 gb ram
500w psu

im hoping for a magic Driver fix from ATi or IW.

The game is new, I'm sure their will be a patch and/or a new driver that will make things nicer down the road.
