Title: opengl ARB_Vertex_Buffer_object
Post by: ninogenio on May 11, 2007

ive been looking at ways of speeding up my rendering of complex meshes and ARB_Vertex_Buffer_object seems a pretty good sulotion gaining me around an extra 200fps in some cases but my question is do alot of cards support it cause if so i will definitly be using it.

Supported by all cards/drivers that do OpenGL 1.4.  I don't know how many that is, and it can be supported in any previous version too.  You might need to check glGetString(GL_EXTENSIONS) to see if it contains "GL_ARB_vertex_buffer_object" before you use it.  FWIW, my ATI X1600 with the latest drivers supports this extension.
