Crysis 2 is finally getting it's DX11 patch after months of it's launch but in order to get a taste of what to expect in DX 11 here is a video shown at Computex
All I can say is that the game looks mind blowingly awesome it's almost like scenes from a CGI movie but in a game! Although it is not on screen footage you can still see something right? I am scouring YouTube for a better quality video but so far it is without luck, but for now you can just imagine what the game would be like once the DX 11 patch IS released.
I for one would like to see current generation DX 11 cards benchmarks and see if the new CryEngine really is better in terms of DX 10/11 graphics in terms of performance and looks.
