When the PC demo is released on March 1st 2011 will it come 3D ready for me to go to the settings and select 3D ?

If you have a 3D monitor, I guess so. The Xbox demo supported 3D apparently, so I see no reason for the newer demo not to.

Actually the 360 demo was not really in 3D. I read an article today where Crytek said they kind of half assed it. Thank god because I was quite disappointed. Apparently the 3D in the final game looks way better.

Well, the 3D look fine on my monitor. And I hope it looks even better coming from my PC.

I only heard good from the 3D in the XBOX 360 Demo.
