I'm using the
radeonhd driver. On one of my other systems, which is also with an ATI video card uses the
ati driver and everything works fine - OpenGL, direct rendering, etc.
I think that the
radeonhd driver is not that good at the time, but I hope that it will be improved since AMD/ATI started to develop an open source driver for their cards, but time will show.
I'm running this system dual booting - WinXP/FreeBSD because I have to use some of the windows apps like AutoCAD, Pro Engineer, etc. and now it seems that I'll have to watch movies under Windows
