Is a smaller object better for the framerate I was wondering if having a smaller object would cause the frames to drop less when animating and if so what are the drawbacks.
I have a background that is really big so i decided to ask this to know how to keep the frame rate from dropping too low.

i am using blender render to do this and i am using a castle as the background.
i just used the scale button to make the background bigger so i would not have to constantly scale down the characters that go in it.
i have used a few methods of making the frame rate higher such as using simplify and turning off shadows.
Having a large mesh zoomed out would be almost exactly the same as a scaled down mesh zoomed in. The scaling usually doesn't effect framerate, the complexity of the objects and amount of objects on screen are the two big things that effect the playback rate. If you're having trouble with playing back at the framerate you want, try putting things in different layers and working on each piece separately, then render them all together.
