We actually really shouldn't call this Catalyst 4.7, it's just a newer build released after the 4.6 release from ATI, station-drivers.com leaked them onto the web. There is no word on performance just yet. If you like to learn more about these drivers then please visit out ATi drivers forum section.
We repackaged the driverset and brough the file-size down towards 22 MB. This is the full release including drives, control panel and WDM capture drivers
If you decide to install this set then remember, this is a BETA version; you use it at your own risk. Don't go complaining to ATI if it does not suit your needs and wishes.
