the graphics cards supported by the two drivers in this package overlap considerably. Previously, this created confusion for users as they selected the driver to use with a particular card. A preferred driver is now specified for each card, and if users select the non-preferred option, they receive a warning that the particular combination of card and driver is not a supported configuration. This clarifies the use of the drivers in this package. Existing configurations will continue to function, regardless of the combination of card and driver.
