My video card isn't quite up to snuff but aside from a couple of drops in framerate I can fly around all of the Crimea map with no stutters at all.
Make sure you do three things:
1) In the nVidia control panel make sure that your IL-2 profile is setup to have "Threaded Optimization Off".
2) Also in the control panel for your IL-2 profile turn VSync off.
3) Get the latest DLL's from this thread:
http://forum.1cpublishing.eu/showthr...highlight=DLLs There are several variations so I'm not 100% sure on which you should use but be sure to ALWAYS BACKUP YOUR CURRENT FILES before you install the new ones.
I had microstutter problems on account of the nVidia card and the dual core system. Aside from that...very few performance issues.
