There is little information on performance of graphics hardware with FOSS drivers. The only widely-known source is the free3d.org site, free3d.org which collects 3D performance information—specifically 's Radeon X800/X850 as recommended for "best 3D performance."


MANUFACTURER SUPPORT

  • ATI: X.Org fully supports the Radeon R100 and Radeon R200 cards. Radeon R300 cards are supported by a new reverse engineered driver under development. DRI Wiki - R300

  • AMD: In June 2007, the X.Org developers announced initial support for the AMD R500 graphics card. The work was done independently by reverse-engineering.1 In September 2007, an AMD representative said the company will make specifications and a skeleton reference driver available for the R500 and later devices; a 2D free driver is expected by the end of the year.2

  • for switching Video Modes ; as some BIOSes include only a limited range of modes, this provides more reliable access to those supported by Intel video cards.

  • Matrox provides open source drivers for their chipsets older than the G550; newer chipsets are only supported by a closed source driver.

  • 7. Fedora 7

  • SiS and VIA have both shown limited interest and communication regarding open source drivers; however, both have released source code which has later been integrated into X.Org by FOSS developers.



ISSUES WITH BINARY DRIVERS

There are a number of objections to binary-only drivers. These may be philosophic, with some feeling that drivers distributed without source code are against the beliefs of the

Writer and computer scientist Peter Gutmann has expressed concerns that the Digital Rights Management Copy Prevention scheme in Microsoft's Windows Vista operating system may limit the availability of the documentation required to write open drivers as it "requires that the operational details of the device be kept confidential."8
