OK, so we are getting DirectX 11 now but what about 64 bit suport (like Crysis and Farcry had) and what about DirectX 10? still plenty of people that got systems with cards that can not run DirectX 11...

What's wrong with the game?
I have Windows 7 64-bit and it works fine.

There is a DX10 check your Crysis2/bin32 and you'll see there's d3dx10_42.dll but most likely will be use with DX11 patch. I don't really care about 64bit since FarCry didn't really use no more then 3GB RAM and 3FPS deference the same thing I can say about Crysis, I personally couldn't see a deference in 32bit and 64bit but a 3 FPS via benchmark 4GB vs 6GB of RAM (my motherboard registered 4GB with Win7 x86 I don't know why). BUT! if you are one those people that run programs in the background like FRAPS or use Crysis 2 for 3D stereoscopic then I understand why.
