WINE Developers Start On Direct3D 10 Support

Well you would be wrong.

Thank you very much for posting that link. I learned something today.

How exactly would microsoft stop AMD and nVidia from leaving Direct3D support in their drivers when they compile them for linux?

Unless I'm mistaken, Vista pipes OpenGL through Direct3D in Vista, severely degrading its performance. This makes OpenGL a ton less attractive to game developers. You can't turn around and blame /them/ for not supporting it under conditions like that.

When it comes to 3D api interoperability MS does already offer that by supporting openGL. If your going to sue someone you would have to sue the game developers.

'Lindows' was asking for it, they got it, and no one cared.
The day Crysis runs on Linux is the day MS market share goes out the window.

The UN and anyone else who is demanding that microsoft improve interoperability. There are very real fines for noncompliance, and going out of their way to /stop/ windows 3d applications from interoperating with other operating systems would be very likely to not help their cause against those fines.

Do you seriously MS worries about bad PR on a lawsuit? They have sued and successfully won over the name "Lindows" for crying out loud. Who are they gonna tick off if they do? The same people that are already ticked off at them, it wouldn't hurt them in the least.

You can patent an implementation. You can't patent an interface. Suing for reimplementing Direct3D on any level at all would fly in the face of all their 'interoperability' efforts and would constitute very, very bad PR. Since what I propose amounts to for the most part AMD and nVidia leaving their D3D code in when they compile drivers for Linux, and perhaps some shim with X, the companies involved would be doing little if anything /new/ that they could be sued over, and the rest of the implementation would be too drastically different for a 'good' patent to really be applicable.

BTW:

"In 1981, the Supreme Court stated that "a claim drawn to subject matter otherwise statutory does not become nonstatutory simply because it uses a mathematical formula, computer program, or digital computer" and a claim is patentable if it contains "a mathematical formula [and] implements or applies the formula in a structure or process which, when considered as a whole, is performing a function which the patent laws were designed to protect"."

This is exactly the reason why commercial distro's do not include libraries such as lame and mad into their official distros.

In the case of DirectX, you better believe that Microsoft would win, and quite easily at that. It's simply not a case of a "grey" area here. If foss could destroy patents in court don't you think they would have done so on much smaller fish first going against Fraunhofer and the likes?

I'm saying that with any given patent used against us, we could probably either dodge it or get it invalidated.

Microsoft can't take us over patents, IBM, RedHat, Intel-- we have more than they do. It'd be a patent Armageddon. Microsoft would lose.

OK, first there is this thing called reality. You don't think that there might be thousands of patents involved with DirectX or are you living in a realm where MS produces opensource APIs? Second of all, why can't you expect publishers to compile against winelibs? They also have a choice to support crossplatform API's. That's exactly what they are doing on the Mac side with Cider. Third, if it's a growing pain that you are not willing to go through then no other OS other then Windows is for you.

I said you /can/ expect publishers to compile against winelibs.

Cider seems to be doing the same thing as WINE3D. If it actually /works/, and if the performance is actually decent, then, for one thing it's farther along than Wine3D, and for another I might consider taking back my claims.

I stopped playing games entirely when I switched to linux. I'm the opposite of the people I describe. Since that time I've picked up tremulous and nexuiz.

Who cares?

If FOSSers weren't so fricking picky about their gpu drivers maybe linux would have games.

I'd rather have Direct3D9+ than OpenGL 3.

You can expect publishers to compile against Winelibs.
You cannot expect them to translate their graphics APIs.
Until Direct3D performance is equal to Windows or better, people will still use windows for games.
Some of those people don't have time to deal with two operating systems, and it's all or nothing.

Linux needs Direct3D support in its GPU drivers.
