Cutting off render time

What kind of ways there are to cut off rendering time? Longer render time equals higher quality. Though most of the times in-game graphics would do the job I’m looking for. So I’m not looking for idea how to get totally rid of shadows and lights, but faster rendering.

Tips and tricks :eek:

Bake textures to your materials, set them to Shadeless and don’t use any lights. Use as many threads as you have cores available to render with. I don’t know of any faster way to render. You won’t get any shadows like this but it renders super fast.

Render at a smaller image size.

Turn off raytracing.

Don’t use ambient occulsion.

Don’t use transparency textures or falloffs.
