Hello All
I'm wondering Whats the benefit of using the multitexture extensions?
Is it any faster than binding a texture do a pass, bind another texture do pass and so on..?

Yes. If your card supports multitexture, it can render both fragments simultaneously in the same amount of time it would take to render 1.

However, multitexturing is less flexible than multipass, unless you use the texture combiner extensions.

This isn't strictly true. There is an overhead for using multi texture but it's faster than multi pass.

It's my understanding that on modern NVidia cards at least, it is exactly as fast for two textures as it is for one...

Got it...is a big advantage.
