I've always wondered what does the option "Use vertex buffer" does? Playing around with it doesn't seem to do anything obvious...

Also, what does "Camera textures offscreen" really do? Does it matter if I turn it on or off?

Vertex buffers are supposed to accelerate rendering. On NVidia they might provide a small speed increase but on ATI they have no positive effect whatsoever.

'Camera textures offscreen' means that camera textures are always created in an offscreen buffer. Normally they are rendered on the screen, then copied, then overwritten by the actual screen.

I have heard reports by some people who have problems with the on-screen method but since for the small textures that are normally used the on-screen method is faster it's merely an option. If you define a camera texture larger than the screen it'll always be done offscreen.
