S!
Without going into FM/DM or effects and other stuff I must say this after testing the demo. If WoP is based on IL2 engine then PLEASE give that code to IL2. I ran the other demo for VVS flying La7 over Berlin. There is a LOT going on with artillery and flak firing, battle raging on, smoke pillars rising all over Berlin and planes plummeting down and of course lot of planes and buildings. And there is NO STUTTER whatsoever! The game runs smooth. Try same in IL2 and you look at a slide show at best even with most powerful rigs
Another thing is that WoP demo worked without ANY tweaking in graphics or similar on ATI 5870HD card. If it uses OpenGL as IL2 (have not checked so deep yet), then please add the same support from WoP to IL-2
I dare to say if IL2 engine got the improvements shown in WoP, then SoW would have a VERY strong competitor as IL2 has a ton more stuff already in it what SoW will not have at release..and most importantly runs on lesser hardware as well. Just my 2 cents..
