actually, aaron have to disagree with you there. The 30 FPS rule is different on highly detailed games. It has to do with many different aspects. TV, this is true, as it is true with movie theaters. With a TV distance and pixel size = poorer quality, in a movie theater you have a motion/blur effect due to white wash, or light that comes back to us from an after image, this in essence blurs what we see and makes it look good. on a monitor, you have a proximityxdetail(via software)x detail via pixel size. We can actually see upto around 70 FPS, at times. This does, however, depend on how nice the game looks. Now, the idea that the 360 is lacking because of this is COMPLETELY WRONG! The 360 can support faster FPS than this, but what is happening is the PC ports are locked at 30FPS to make the port less of a hassle. The 360 can in fact support much higher resolutions. Take quake and prey for example, they are just ports, nothing is really improved upon. 30FPS is NOT bad, but it can be better. Oh yeah, as far as fluctuating, that is true. its a locked speed, which really helps out alot. It is just easier to port this way, that way much of the code and details dont have to be rewritten to take advantage of hardware. Its really a problem with the software developers not wanting to go the xtra mile.
