Well, I’ve been using VBOs and Vertex attributes together, and i get a massive double FPS over VAs and Vertex Attribs.
I dont know why its not working for you, but i have a GF5900XT with 66.93 drivers so its probably your card’s drivers. Is anyone else having probs with VBOs and Vertex Attribs on ATI cards?..

[EDIT] Oh and i forgot to ask, are you combining VA and VBO data in your rendering? because thats been known to slow things down, i dont think as much as your seeing, but it could be a contributing factor.
I’ve had the same problem on Radeon 9800, so it definitely looks like the driver’s fault.
Switching (back) to texcoord abuse doubled or tripled my frame rate (about a million vertices per frame).

Exactly.
