I know there exist tools to organize meshes in terms of spatial coherency, and I think this is because there''s a vertex cache on the graphics card that is faster than fetching the data from main memory, but it is of very limited size. (Is this right?) How (or where) would I go about finding the size of this cache? Does it vary much from card to card? Does anyone have a rough idea how big it is... just roughly, like 5, 10, 20, or 50 textured vertices?

Ahhhh... Google! *is embarassed*

So that cache is around 10-20ish vertices depending on the card:

Radeon 256 - 6 vertices
GeForce256 & GF2 - 16 vertices, but effectively 10
GF3 & GF4 - 24 vertices
