Performance Issues with 7850

I have had the AMD Radeon HD 7850 2GB for awhile now, I never had much of a problem with performance. But when I bought ArmA 2: Combined Operations, so that I could play DayZ, I get about 10-20FPS. My friend who owns a 6870 said he gets about 40-50FPS, why is his running better than mine?

I have the 12.6 Catalyst Drivers and here are my complete specs:

Windows 7 64-bit Home Premium
8GB DDR3 1333MHz RAM
AMD Radeon HD 7850 2GB
AMD FX-4100 Bulldozer (Quad Core) 3.6GHz

EDIT: Resolution is 1280x1024
I also have dual monitors, one is 1280x1024 and the other is 1440x900

I've found in one of the games I play that if you enable AF and AA in the game that you suffer a massive performance hit. Disable the game's Anti-Aliasing and Antroscopic-Filtering and enable it in your Catalyst drivers instead. That's the first thing I would try.

One thing you left out when posting your specs is your resolution. What resolution are you running?

Beyond that I would make sure you and your friend are running the exact same graphic detail settings.

I updated the first post with the resolutions, I will try disabling AF and AA.

You want to make sure you enable it in the Catalyst driver otherwise the game will look awful after you disable it in the game. This is something that I recommend rebooting after making the changes.

How exactly do I enable in the Catalyst driver?

I don't have the driver in front of me, but if you click through the different settings look for one that says Anti-aliasing as one of the first few settings. There's a check box that says "use program settings." Uncheck that box and set it where you want it. Then reboot. I would also uncheck the setting for AF it'll be on the same screen further down. I realize that is extremely vague, but if you right click on your desktop and go into the catalyst control center or whatever name the 12.6 driver version has for it you should be able to find it without too much trouble.

It didn't help, unless I'm doing it wrong.

It isn't a fixall, but it certainly was worth a shot. Unfortunately it sounds like you'll need a better expert than me to find a solution.
