AMD has released the new 7.10 version of ATI drivers for Linux.
It is good to know that AMD is taken seriously Linux users, this time Linux boxes will have support for AIXGL so, 3D acceleration will work now better and therefore Compiz and 3D games will have better performance on Linux.
According to AMD the supported cards by this new version are:
ATI Radeon X1000, X800, X700, X550/X300, 9800, 9700, 9600 y 9500 Series.
I have installed it, on my Debian Etch with an ATI Radeon X300, and now I have Compiz working, but still have some problems.
I am writing in the forum how I configured it, and my problems. Please check it here, and give your opinion
