Re: [Trisquel-users] Nvidia or AMD for Free Software?

WINE is an implementation of the Microsoft Windows APIs on GNU/Linux.  The  
graphics chipsets have little to nothing to do with it really. DirectX calls  
translate into OpenGL I believe. This is for compatibility with GNU/Linux.  
DirectX is a proprietary Microsoft solution though. Chances are if the games  
you are looking at work on GNU/Linux with it the software is not free.

In theory however you could write something for Microsoft Windows, release it  
under a free software license, and use the WINE technology to “port” it  
to GNU/Linux. Then it would be 100% free.
