"Doom3 is up to 112% slower than the 6600GT"
- Nvidia PR doing the math. The X700 apparently renders at a negative framerate in Doom3.

Well how fast is the animation of your demo test?

If GL_VERSION says 2.0, then it support 2.0 and nothing else. Some stuff may be supported only in software though. There's no way to query hardware support in OpenGL. That's by design, you're not supposed to care HOW it's done, only WHAT is done. In practice however, you often care. Your best bet is to go by the unofficial convention among the IHVs that you only expose extensions that can be hardware accelerated. So check the extension string instead of the GL version. But there are still no guarantees, and you may miss hardware features that's not exposed as extensions, such as NPOTs that we support in hardware but not 100% of the functionality of POTs.

We support the 1.10 version of GLSL, and none of our cards support vertex texturing.

Ok, perfect, given those unified driver models, if I have an older card which does not support a 2 sided stencil and non power of two texture for example, what GL version will report the driver ?
If driver reports gl2, if core GL 2 is exposed, but there are no name strings to figure out whatver the cared actually suporrts a double sided stencil, what is the way to figure it out ?

Also, what GLSL version is suported on ATI cards?
Do any ATI card alow vertex texturing ?

Too bad the only game I play ( NFSu2) has now a lot of texture corruptions :-(

It's supported through the GL2.0 API, but not through the GL_ARB_texture_non_power_of_two and GL_EXT_stencil_two_side extensions.

Sorry but im a bit unclear here ...

the guy said that he has no support for double sided stencil and non power of two textures ...

Aint Opengl core supose to HAVE those APIs ? So if those are not there, regardless of what version strin says, he has no OpenGL 2 support.

No, I don't.
