il 2 sturmovik: Cliffs of dover (low fps)

[RaM85]

Maybe this has been already posted many times before, but I played COD with my friends yesterday for the first time. 3 of us have NVidia graphic cards and we all had very low fps issues on mid and (in some cases) low settings. Now, I have an AMD q9450 cpu 4gb RAM DDR3 and a Ge Force GTX 280 and on mid settings with AA x2 in country and sea maps I managed 15-20 fps at best. One of my friends has 8gb RAM and 2 GTX 285 SLI and he can manage my amount of fps only on low settings (wich visually seems like a pre- IL2 Sturmovik game). On the other hand another friend of mine has an almost identical setup of my pc, a part for an equivalent ATI of my GTX 280 (I don't remember the model now), and he manages to play on FULL settings at 25-30 fps.
I saw in different forums and also youtube that ATI cards owners have a much more fluid experience of the game, while Nvidia ones barely manage to play it at all. I really hope the development team fixes this soon also because even in my few fps i can tell that this is an astounding simulator. Peace
