[Dri-users] Mobility Radeon 7500 very slow...?

[<Ram...@fr...>]

Hi All,
I have (Notebook N620c) Mobility 7500 32MB.... the ATI driver can go
only starting from 8500....! the OpenSource "radeon"  driver is very
slow :( does it give possibly makes as faster? HyperZ is activated and I
all options in xorg.conf tried out and Ut2004 have only 15FPS and under
Windows has  35fps or 40FPS :(
(my English is not so good sorry)

why is OpenSource driver "radeon" so slow?

Thanks!
