9 That used to be true, and nVidia historically did have the better performance
10 and support. But two things have changed:
11
12 The newer GPUs (starting with 8xxx and 9xxx series) do not have 2D
13 acceleration in hardware anymore, it's all done in the driver. Some Linux apps
14 and especially KDE4 use X technologies in ways that nVidia's driver is not
15 especially good at. Remember that the Linux driver is essentially a port of
16 the logic in the Windows driver together with the guts of OpenGL ripped out of
17 X and replaced with nVidia's stuff, this leads to a bit of an oops. nVidia is
18 actively working on the problem with reasonably frequent beta driver releases,
19 but it certainly appears to be way more deep rooted and trickier to handle
20 than it might appear.
21
22 If they could just open source the drivers, then an entire army of coders
23 would step in and help devise good code that runs well. But they don't, so
24 nVidia is stuck with the 2 maybe 3 people they have on the Linux port.
25
26 And there's also the fiasco with the construction of apparently their entire
27 line of recent GPUs. They don't react well to thermal stress and are failing
28 in alarmingly large numbers

34 It appears you were more right than those others were wrong :-)

36 Thumbs up to AMD for taking the first steps and releasing some decent docs
