For those who are wondering about new hardware... I've been "videotesting" my new Pc... Rise of Flight triggered for me the need of new hardware, but obviouslly I will keep flying in Il-2, so it's a comparative performance test; full mods in IL-2 vs default Rise of Flight. Both at 1920x1080, Ambient occlusion On, AA and Aniso at 8x as forced in Nvidia control panel (I don't use NHancer).
Mod pack used was Ultrapack 1.7, not intending to spam nothing here. The reason is that it's hardest to run smooth with all effects on. UI and other packs, and of course, default 1946 should run even better than this. Anyway, I still have to fine tune conf.ini...
None Il-2 or RoF gave me any single problem running under Windows 7.
For those flying other simulators, I also videotested in my machine FS2004 (finally full graphics capable), FSX (lots of problems here!), X-Plane 9 (amazing autogen crowded scenarios!), Condor (rock solid at 60fps), Black Shark (good performance), Lock On Gold (some shadows bugs). The other 3 videos with those tests are on my Youtube channel.
In all cases, consider there are some loss in fps due to fraps capturing video.
