The game is designed for consoles, so we do not support all features on PC.
Typical development PC is something like GF8800+, Core2Duo+.
It allows game to work.
If you want to play HD(1080p), it needs to be GF9800/ATI4870.

But once again, the game doesn't support all features on PC, the graphics engine is developed for Xbox360/PS3.

I am guessing how large maps will they be on Birds of Prey?. 20x20km, 50x50km 100x100km maybe?.

100x100km average, no less than 65kmx65km each.

The same trailer, but without GoW ad in the beginning.

If not track ir, what about freetrack. You could integrate this and purchasers could provide a single red LED for simple 2 degree of freedom cockpit panning. It would be a feature the massmarket has never had before just like the wii captured their attention. Just imagine all the tv reports of 'the amazing virtual reality flight simulator that teaches terrorists to fly on the nintendo360'
