I'm actually surprised it's running as good as it is.
Compare the detail in the maps to what we've got in IL2. What we've seen just blows IL2 away.
There's a benchmarking tread
http://forum.1cpublishing.eu/showthread.php?t=17195 looking at a track called "FinalDaysBenchmark". Although generally playable, at the start when it's over a populated section of the map it brings most modern pc's to their knees! Compared to what was in those SOW video's IL2 is a barren wasteland!
Well done Oleg and Good Luck with the remainer of the expo!
