Large Vertex Array Crash with VBO

Hello. I have the following problem:
I use the ARB_vertex_buffer_object extension to buffer my vertex array (float * VertexArray) in video memory. But when i try to cache larger arrays (with more than ~22500 vertices = 270,000 bytes) my program simply stops responding (blank screen). When i turn off VBO it runs normally (and damned slow )
Any ideas would be great! Thank you!

What implementation are you using?

Im using VC++ 6.0 SP5
May i include the code too? (it works fine with VertexCount < ~150)

Try to check what is maximum aviable number of indices in a vertex array like this:


Hope this will help.

@orbano: I guess Korval wants to know which videocard+driver you are using

There are no such variables defined in the ARB_vertex_buffer_object extension. (the standard ogl vertex array works fine)

Im using Radeon 8500 with catalyst 3.9

Try the Cat 3.10’s.

it crashes too. even with radeon9700
