OpenGL 1.3 + GL_SGIS_generate_mipmap + WGL_ARB_render_texture ...

Gotta say these 3286 driver rock even for older Radeons. Now we have OpenGL 1.3, the GL_SGIS_generate_mipmap and WGL_ARB_render_texture extension plus some extra performance and added stability in XP. I haven't tried those extensions out yet, but will do that soon, I have always wanted those. I have to say thumbs up to ATi for those drivers! :)

I have one question though ... how far down the pipeline is the GL_ATI_vertex_array_object extension? I assume it's going to be supported on older Radeons too? When can we expect to see it?

So far only the generate mipmap and render texture extensions are supported on NT based OSes, do to NT having something in the kernel that Win9x doesn't have (ATI is working on a way around that).

I think the vertex object extensions are at the top of the geo pipeline (before transform), but it can be stored in AGP memory so it can be transfered to the card faster using DMA (like with the nVidia VAR extension).
 
With "how far down the pipeline" I meant "how long until we have it in the driver", I just used that as an expression, I'm not particularily interested in where in the hw pipelines it operates. :)

I'm working on a new version of my old GL_EXT_reme benchmark and want to be do some better T&L benchmark with vertex arrays and support both GL_ATI_vertex_array and GL_NV_vertex_array_range extensions. I suppose it's available for 8500 already (?), but since I don't have one yet I wonder when it'll arrive for older Radeons.

Oh.. Um, that's a good question... Perhaps you should email that to [email protected]?

It's already on the 8500.
 
Yeah, that's what I'd usually do, but since "the good folks at ATI Research have agreed to provide input where appropriate" in the forum as stated when this forum was openened I also wanted to try out if I get any answers here. :)
 
We definitely intend to expose ATI_vertex_array_object on RADEON but I don't have an estimated timeline from the GL driver team. It doesn't make sense to expose this extension on earlier chips which do not support T&L in hardware.
