Personally I love crysis games and i think it's excellent for dx9 and can't wait for dx11. Currently i can run it at a low rez with max settings with 60+ fps. But, I am worried that dx11 will cause my laptop to overheat or make my performance very crappy. Some people have told me it won't and might make it perform better. I'll see what happens i guess.....
Absolutely cannot wait for MOD stuff and sandbox 3. I hope intel holds another one of those contests where people make the best levels they can like they did with Crysis 1, there was some very good creativity there.
