Everything you've seen has been running on DX9 and normal hardware you can get in the shops right now. It's all normal spec and doesn't even use a dual processor or anything like that, we don't have any special graphical hardware inside these boxes. However, with DX10 and a dual core CPU, you're going to see something very special indeed.
When we compare Far Cry to Crysis we're talking about two to three levels better in terms of generations, but if you compare DX 9 to DX10 it's at least a generation better, so there's a tangible difference, visually as well as from the intensity.
The game is currently set for a Q1 2007 release, which means somewhere between 1 January and 31 March, though Crytek has said they do not have to wait for Vista, which won't be available to consumers until January anyway. It seems that while DX10 will add Shader Model 4 effects (assuming you have the next next-generation ATI or NVIDIA hardware that supports it), it won't be a requirement.
The game will be playable at E3 in a couple of weeks and we'll be there reporting live. Personally, we can't wait!
Esto es lo que dice un responsable de Crytech.
Lo lanzarán antes de Vista, por lo tanto será DX9. Imagino que posteriormente sacarán un parche para implementar SM4, al igual que hicieron con Far Cry y SM3.
