Increasing it may help (up to say 64 or 96) on a card with a large 
amount of VRAM but as Ryan says, VARSize controls how
geometry data is cached in AGP memory, that is, the _Size_ of the 
_Vertex Array Range_, NOT the amount of VRAM you have. If you allocate 
your entire VRAM to VARSize you could have problems with other data 
having to be moved around between system memory and VRAM, thus slowing 
things down.
There are also some differences between how the PC and the Mac handle 
AGP memory, so you cannot directly compare the two.
