8800GT World in Conflict

I was wondering if you guys could give me some help. Ive got a Quad-Core, Phenom 9600, with 4 gb of ram, 500 GB hard drive, and windows XP. I just got my new video card, an EVGA 8800GT (512mb ddr3). It will run Crysis on high settings at 1680x1050 at around 40 fps, so i know it works well. But the only problem is, when i run World in Conflict, on medium-high settings, at 1280x1024, i get around 20 frames per second. I'm dumbfounded. I've checked all the benchmarks for the card, with similar test rigs to mine, and it SHOULD get about 40 fps MAXED out. I have the latest dx9 version, and graphics card drivers. Help anyone?

The benchmark in that game is biased towards cpu use (physics calculation), especially in the bombdrop scenes. And since it's not optimized for quad cores, your cpu is probably the bottleneck if you notice severe drops in that sequence.

I'm running WiC with that same video card (PNY version). I always get between 21 and 24 average fps in the benchmark with "Very High" settings and 1680x1050 resolution. I used to run it in 32bit windows xp, but currently I'm using 64bit vista home premium, both with nearly identical results in the benchmark. Nothing overclocked in anyway.

Here are the rest of my specs.
CPU: E6760
Mobo: GA-P35-DS3L
Mem: 4x1GB DDR2 800
HD: Seagate 250GB 7200.10 SATA 3.0 Gb/s
PSU: Xclio Greatpower 550W


Edit: Ok, I just ran the benchmark a couple times using 1280x1024 and medium settings. I got 64, and 65 as the average fps. Also note that I'm only running at 2GB ram at the moment as I had to RMA a couple of bad sticks. The only difference I see in our specs is the CPU. I know WiC is more processor intensive than most games. Perhaps someone more knowledgeable than me can jump in with how our 2 CPU's compare.

Maybe in medium setting the game is cpu dependent but I doubt your cpu makes a big difference in video card limited situations like high or very high settings at your desired resolution.
