inCrysis has published an interview with Intel. In this article they mainly talk about the upcoming Crysis video game:
What kind of performance difference will we see in Crysis between Single/Dual/Quad/ core processors?
You will see a large performance increase on multi-core processors, especially regarding the worst case frame rates during intense action sequences allowing the player to experience a more stable frame rate through out the whole game. A quad core system should provide the best gaming platform for Crysis.
What technologies, effects, enhancements etc. will we see in Crysis with the use of the multiple core processors?
The most significant enhancement is the increased frame rate but it doesn’t stop there. Multi-core systems benefit from being able to generate much more complex visual particle effects using the additional cores to offload the work from the main game code.
