BC2 and MOH use the same engine afaik. So explain me the difference, why does MOH run twice as fast as BC2 runs? The engine does not set the intensitivity.
Its more about whats loaded in the memory, how many active elements are on the field etc. Also, depends how well the code is built. GTA IV runs on shitty a** RAGE engine wich cant provide any sense of realistic graphics and yet needs so much resources. Same with Cryengine, the new engine is promised to run faster and as u already now - it provides many upgrades and some more fancy stuff.
Ontopic, i wonder if this game will have a long support. Also the destruction of the buldings is awesome. In IGN reverse theatre they saw that even small bricks go boom. Not just whole walls.
Edit:
Dont rely on just the specs they recommend.
GTA IV has pretty intensive recommendations too, yet there are people who play it with Pentium 4. Those recommended specs are just wrong. They give u a picture to understand a bit - how intensive the game is. But dont be like "it needs dual core".
Right now im listening trough my broken Creative HS-1000 headset. Usually im with my lovely vintage 2x RRR S90's (30w rms) and annoy my neighbours with them (being very serious, people who know about audio - will understand).
Well, if it gets stuck on my PC - i cant even drop the slider back on the timeline. Its just stuck on the cursor. Might be a bug of flash player, but meh ...
Try changing the steering centre in Options > Control - too. If thats too high, the steering in centre is slow and the more u turn out, the faster the rate gets.
