this is interesting I get like 70- 80 fps
with those settings, I turned off Shading it is not optimized very well.

no GTX 680 here.

thanks for all advices and recommendations, so now i have ssao&vsync OFF, AA 2x, fullscreen ON, building textures: medium, all the rest is set to high

im having now a very good fps (average 30-35fps) in missions with lots of different ai hardware here and there etc

i tried the quickmission flying over London with the previous settings set to full: i got 11fps (instead of 4-6fps before) :o)

but there is still something weird: despite that im having GRASS set to ON, i have never seen it! everything is dead flat

opps thats cause you broke some thing try repiaring netFX frame works. its in the user/soft1c/il2/redistrubute folder

The Windows Experience Index will analyze a problem, and I think make system graphic adjustments.

I got almost the same machine as you have. All settings at high. 2xAA and grass and shadows enabled. With a GTX570 and I2500@4.3 I'm getting around 50fps. It does get below 50fps though (low teens)when I fly close to explosions. I should get my 680 in this week. Somehow I don't think it's going to make that much of a difference. Just a bit faster with less power draw and heat. I'll make sure to do a few benchmarks before and after the switch with the same game settings.

Texture Quality Original
 

Texture quality "original" for sure. If you want dull out of focus cockpits and airplanes that look lower res for a 1/2 fps improvement then switch from Original : )

Luther mentions Original textures in this link and its true in my experience.
