ATI R300: Open v. Closed Drivers
,----[ Quote ]
| Like the R200 drivers, if you wish to use the open-source R300 drivers
| you will likely face a performance struggle even in older Linux native
| games. At this time the Linux fglrx drivers are significantly slower than
| the ATI Catalyst Windows suite, while the open-source R300 drivers are
| even slower. Fortunately, non-gaming desktop users should not facet
| hese performance issues. When comparing the R200 drivers merely five
| months ago the open-source driver's performance was almost cut in half,
| and our tests today yielded similar results with the Mobility Radeon
| X300.
