Hello,

The idea is not to return the exact videocard but a close match (a card supporting more or less the same opengl features or with similar performance). Based on test using the closed source drivers from nvidia and ati and also using the opensource radeon dri drivers, I made a list of what extensions are available on the cards. Further I checked which of the extensions indicate correspond to certain directx versions.

You may already be aware of this "Graphics Card Comparison Guide" but
in case you don't here is the links, it may help in the match making

WineD3D: gpu detection

Can we tie the gpu detection in to supporting fake/real alpha blending?

No it's must be implemented using usuals GL caps queries :)

WineD3D: gpu detection

[Roderick Colenbrander]

All capability detection should be based on opengl extensions. In most cases when there's no opengl extension which can provide the functionality we can't support it. Recently I have improved our capability reporting quite a bit. Some of the caps from the page you pointed to are now reported but also a big number of them isn't reported because wined3d doesn't support those yet. Reporting caps which we don't handle is very bad, it would break games.
