Re: WineD3D: gpu detection
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.

Can we tie the gpu detection in to supporting fake/real alpha blending? http://bugs.winehq.org/attachment.cgi?id=2936&action=view http://bugs.winehq.org/show_bug.cgi?id=4050

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 process...

Small note: GeForce4 MX is not a DX8 capable card. It's a souped-up
GeForce2 MX and labelled "4" for marketing reasons. So perhaps move that
check into the DX7 branch.

Lots of programs use these ids to get an idea about the capabilities of the card, enable/disable features based on the detected card or sometimes they are used for evil purposes aswell (working around bugs). Compared to the first method which I described which solely relied on the parsing of renderer strings this method is better because it takes into account the opengl capabilities of the videocard. So when a new card is out which isn't in our list, we won't fallback to a very basic card but can still return a 'close match' because of the opengl extension checks. This patch is a nice idea. Some games query pci ids and do stupid things with it if it gets one it doesn't recognize. Using fake ids of a common card will help some. This potentially means that Wine will have better compatability with older games on newer hardware. For me this fixes a problem with battlefront under wine where battlefront sees CARD_WINE and turns everything to low and disables use of programmable shaders completely. It was very annoying because there was no way to force shaders back on in the game. I wrote a hack to fix it, but now I'm glad there is a patch that does this lots better! Thanks Roderick, Jesse
