It works very well on Matrox cards, other cards are not yet supported by DirectFBGL on DRI. > Do you take the performance hit that comes from context switching, or does > the user have to pick either DRI or DirectFB accelerated drawing when the > program starts? There's a lock for the graphics accelerator. The context switches are very rare, practically each time a GL application starts/finishes rendering of a whole frame. The switch to DirectFB adds just a few register writes anyways. > Or, is it possible or desirable to let the DRI driver replace the DirectFB > driver entirely? In the far future a generic DirectFB graphics driver on top of OpenGL could add acceleration to chips that only have good DRI support. -- Best regards, Denis Oliver Kropp .------------------------------------------. | DirectFB - Hardware accelerated graphics | | http://www.directfb.org/ | "------------------------------------------" Convergence GmbH -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe directfb-dev" as subject.
