This is the ATi Radeon X800 Driver, Leaked version 188.8.131.5244 Normally this driver would have only worked on x800 graphics cards. Yet FrancoisC modified the .ini files, we merged the two and now they work with all Radeon graphics cards.
Also we crunched down the file-size from a 24 MB download towards 18.7 MB. The drivers should be considered highly beta ! You can look at it as the new Catalyst 4.5 driver .. yet of course it isn't.
