“Earlier this year we had compared the open-source ATI display
drivers against the closed-source fglrx drivers with R200
components. Since that point, however, open-source support has
appeared by default in X.Org 7.1 for R300 generation GPUs. While
ATI does not officially support these R300 open-source drivers,
this alternative have been gaining momentum with users largely due
to the lack of GLX_EXT_texture_from_pixmap support in fglrx. This
extension is needed for the AIGLX desktop eye-candy. These drivers
do lack TV-out support and many other features found within ATI’s
fglrx drivers, but how does its performance compare? When we had
analyzed the drivers on the Radeon 9250 earlier this year we had
seen the X.Org drivers take a massive beating from the fglrx
drivers. Today we are investigating the performance within the R300
DRI drivers…”
