Just be thankful you are not using ATI hardware where everything prior to the 2400 Series cards were deprecated to "Legacy" cards and all Linux support dropped in March ;-)
(performance difference between fglrx and ati 1066 FPS version 160 FPS, and the downclocking isn't present in the opensource driver (not the gpu powerdown) and temps are up 25 degrees (you feel it in the laptop palm rest).
Heh.
ati 3d support is much more advanced and mature than nouveau one.
And I thought ati had some sort of downclocking support. But I am not 100% sure. From your comment, maybe it can just downclock the mem speed and not the gpu speed ? In any cases, for nouveau it is inexistent. The opensource ATI drivers are definitely in a very good shape especially at this stage of development.
I decided to ditch catalyst* completely the other day until I had to get out and actually use the battery. The battery life dropped 40-50%. I wasn't even aware GPU consumes that much power . So, yes the opensource ATI drivers are great but not for laptop usage. *my card (Mobility Radeon HD 4570 is M92 based which is still supported).
