Here’s a quick benchmark of VBO performance using the latest Catalyst 3.10 drivers.
Benchmark System Specs:
WindowsXP Pro SP1
Athlon XP 2700+
512MB Ram
Radeon 9700 Pro
Catalyst 3.10
The scene being rendered:
1280 x 1024 x 32bpp (fullscreen)
1 cubemap (each face 512 x 512)
1 sky box (display list)
1 sphere (128880 triangles; VBO; reflection map)
Using brute force rendering for everything.
Sphere uses 2 buffer objects - one for vertex data, and the other for index data.
Results:
Using VBO 180 FPS
Using standard vertex/index arrays 34 FPS
5.3 times speed increase using VBO
