Which NVidia drivers are you using? It sure doesn't run great for me, and I've same CPU, 8 gigs of RAM and a GTX 470 Super Overclocked Edition.

I wish the developers had stuck with OpenGL, it traditionally runs the Il-2 engine (on which this franchise is based) much, much faster than Direct3D. Very old Nvidia drivers (pre-170 series or even earlier) may help; I just don't feel like doing the driver dance to see which one works!

This could explain the terrible performance. IIRC this game uses a modified IL-2 engine, and Direct3D was always significantly slower than OpenGL in Il-2.
