i assume u mean pc..
having played it on the 360, bit of a letdown tbh the graphics don't really compare to me its just like graw, but with heat haze and.. well.. thats it really :S
it seems to bug out and crash alot too but that might be just me.
its upto 1.02 patch now so perhaps some things have been fixed.. like the fact when u complete a mission you can't select next mission as its right on top of the 'back to menu' button.. (that got annoying) but i think that's now fixed..
still crashed on me
i'd like to see it with physx but i still don't think it'l be up to what it looks like on the 360, also they've left dialogue in from the first mounted helicopter gun mission on the 360 (omited from pc) which is completely out of place...
overall i guess it's alright but it didn't impress me anywhere near as much as it did on the 360 tbh.
