Vertex Buffer Objects - speed testing

For drawing 32,768 meshes of 12*16*2 triangles each (1 triangle strip):

OpenGL 2.1 hardware:
VA/IA: ~230ms
VBO: ~30ms

OpenGL 1.4 hardware:
VA/IA: ~230ms
VBO: ~240ms

The note is, although your card may say it supports the VBO extension, or support VBO as per the OpenGL 1.5 specs, it doesn't.

VBO's only work in 1.5 GL's or later, due to hardware restrictions.

Remember; If you worry about optimization, you'd better have timing tests to verify that it even matters. Saving about 10% or more is useful.
Also, small frame optimizations are useless; Anyone can do those, and they generally introduce unmaintainable hacks. Worry about your high level optimizations, like using "most common failed test first" and algorithmic and design changes to maximize your logical speed.

Anyways. Here's a buncha UV spheres, as mentioned (generated using xcore + mingl):



Currently working on the texture functions in mingl. Having to write compressors/decompressors for all the DXT formats. It'll be quite useful though.

Z out. Happy Halloween.
