Poor performance - Bad Company 2

[MrHood22]

I started getting poor performance in BC2. I get about 10-25FPS on high settings (usually get ~60). I get about 50-60fps on low settings.

Q6600 @ 3.2ghz
GTX 260 @ 670/1430/1100 Drivers: 266.58
6gb Corsair XMS2 DDR2 800 @ 425mhz, 5:6, 5-5-5-15 2T

Hard Drives:
OS - WD Blue 7200rpm SATA
Games - WD Green 7200rpm SATA

Monitors:
2 x 22" @ 1680 x 1050


I've been playing this game for 2 years and I haven't had issues like this. The most recent hardware I changed was going from 4gb to 6gb a few months ago. However, I have played this game many times after the upgrade and it's fine.


My Temps are fine.
I don't experience any BSOD, crashing, ect.
The only other game I play is CSS and that runs normal.
I have tried reinstalling BC2 and I still get the same results.


Any suggestions?

Memory stick configuration?

You're not using 3 x 2GB sticks are you?

No,

2 x 2gb
2 x 1gb


I'm under the impression that it's generally not good practice to mix and match but they're the same model and frequency. I tested it out and I didn't notice any problems with it so I kept it. As I said, I played with it for a few months before I saw any performance problems so I don't feel like it's related to this.

Update drivers?
Roll back drivers?
Make sure that Q6600 is still at 3.2Ghz?
