I recently installed Win 7 on my system. I installed IL2 direct onto C: drive, updated and put HSFX with all patches. I did the same with my TrackIR and Saitek X45 software. After the installs were completed, I launched the game, not using any compatibility mode at all, with TrackIR and joystick software running..

Everything runs fine, no lagging anywhere that I can see.

Have you tried running it without compatibility mode?

I also use a piece of software from IOBit called game booster, it stops all unnecessary processes and software, freeing up RAM.
