I know that all graphics card since R300(Radeon 9500) and NV30(GeForce5) support VBOs including map buffer, excluding READ and COPY modes but what about previous card ?

I think that NV10 and NV20 hardware support VBOs but without map buffer because these card support NV_vertex_array_range

For ATI card I found ATI_vertex_array_object and ATI_map_object_buffer supported by all card since first Radeon witch respectively support basic VBO loading and VBO mapping. In conclusion I guest that all ATI GPU support VBOs.

Am I right? Have you got more information? For example about drivers emulation.

this site (http://delphi3d.net/hardware/index.php) should be in every GL programmer's bookmarks. It displays what extensions are supported for a given card/driver combination, and which card/driver combinations support a given extension.

It also gives information on maximums, like maximum instructions in vp/fp etc.

I use glview witch contains the same kind of information but for VBOs I need more because all VBOs features aren't supported by all cards.
