Hey, i kept on searching tweaks for my ATI driver on ubuntu to be able to use Pd in a efficient way ('cause the downgrade didn't sound so cool since i just installed 9.04).
I finally found this links, and the tweaks explained in there are really helping. Motionblur works nicely and i can use [gemframebuffer] and glsl-related. CPU is still high&higher but i will look into it. So this stuff could help someone else too in the future:

also tons of other options are available via terminal --> man radeon (but this is not a big discovery)
cheers

mmm.. i found out the truth. i write this just for information (probably most of you already know it but it can be useful to post it anyway).
catalyst 9.3 and earlier drivers don't support x 1.6 and catalyst 9.4 doesn't support a bunch of older radeon cards (as mine). This means the only option one has is to downgrade to ubuntu 8.10.

Thanks Jack, as IOhannes confirmed it is probably a driver problem (anyway i don't think i can make faster my pacth with [pix_snap] and family since they will eat my cpu.., i prefer to manage this driver issue).
@IOhannes
gfx card: VGA compatible controller: ATI Technologies Inc M56P [Radeon Mobility X1600]
driver: xserver-xorg-video-ati 1:6.12.1-0ubuntu2 xserver-xorg-video-radeon 1:6.12.1-0ubuntu2
i suggest using the latest (urgh) proprietary drivers to get decent openGL performance...
yes, keep on looking i found out the same suggestion in other forums. ok, i'll try to install that right away .. (i was afraid to hear it) :P
