Not sure if that is true but I'm told that nvidia use the same source
tree for their win and Linux drivers so you'd expect them always to work
at least as well as the windows ones.
Yes this is the case. They use a unified source tree. Which is cool. It is just a pity they're not more open. But I don't think you could find a graphics company that supports Linux better with binary only drivers than nVidia.
Anyone else had any experiences with ATI and Linux?
