Big problem with FPS

[Random]

Something is very wrong with my setup. At most, in an empty area staring at the sky I'm seeing 35fps. Usually more like 13-20.

 

Now the funny thing is I get these frame rates with the graphics turned all the way down to low/off and 1024x768 and also all the way up on 1920x1080

 

Specs are

AMD phenom 2 x6 @4.1ghz

8GB memory

2x ATI HD6950 flashed to 6970 not running in crossfire in dcs, as its unsupported

Mirrors are off. As I said, i've literally turned EVERYTHING to minimum and not gained any FPS!

that's it. DCS is not optimized with amd cards.with 1024*768 it must give you higher than 60 fps,but it doesn't.trust me you can buy nvidia to see difference.
