I have been playing crysis 2 recently and it has been a major disappointment. It is poorly optimized, worse than the original crysis actually. I can play the original crysis on high but I can't even play this on whatever equates to the lowest setting on their broken choice of graphics without my computer overheating.
Um...not to be rude, but I think the problem here is on your end. Chase the dust bunnies out of your computer and make sure all your fans are working. Chances are if your computer's overheating it's a hardware fault, not the games, especially since Crysis 2's system reqs are pretty tame, considering.
Crysis 2 is much,
much better optimized than Crysis 1 (first game that is, not Warhead). The reason the first game was such a "computer killer" is because its DX10 mode especially was
terribly optimized. It hogged resources it shouldn't have, and at one point during the final boss has a memory leak that results in BSODs. (Never been patched, either. <_< )
I can run the first Crysis in DX10, "Very High" settings just fine (at least until the memory leaks ensue!), although it causes my computer's fans to spin so hard I think it may one day take flight and launch itself into low orbit. Likewise, I can run Crysis 2 on Extreme (...whatever that means, Crytek :wacko: ) just as well, but with a slight jump in framerate and without my hardware working quite so hard. (I checked on my graphics card while running Crysis 2 out of curiosity the other day: the fan speed didn't crank up nearly as high, and the temps were more comparable to what I get playing Oblivion for hours on end. With the first Crysis in DX10, my graphics card got
hot.)
