Try both and see for yourself. You can use ati-12.1 or get the lastest git for radeonhd.
Make sure you have an updated DRM as well.
Hi, I'm following both the xf86-video-ati and the radeonhd development.
I have a radeon hd 3450 card for multimedia purposes.
On my linux box I installed xbmc, wich is good for an htpc.
I don't like the catalyst driver because I noticed too many artifacts while playng movies and I'm reading positive feedbacks on the latest xf86-video-ati 6.12 in the latest jaunty alpha release.
Is this driver better than radeonhd + mesa?
If you want HDMI audio, use radeonhd. Other than that the drivers' performance and features are mostly the same.
Thanks, I'm downloading the new ubuntu alpha right now.
