are you saying it should take an hour to render 2000 frames... ha... with what in the scene ? a box and a 12 segment sphere?
Now if you have actual objects... materials etc.. it gets much slower especially with metals as they require raytraced reflections for accuracy, and glass especially also, and then theres special effects i.e combustion, fog, volume lights and many more that slow down the animation, mostly it is just sheer polygon count that can slow the scene down.... most scenes have 30,000 polygons at least, and also texture size etc... u can almost never get 2000 frames in one hour unless... rendering a box and a 12 segment sphere....
yeah even w/ a fast computer it isn't that fast! i've rendered 60 frame sequences on a Dual Xeon and it takes more than 7 min.... but that may be cuz of lens flare but that takes a few sec a frame
