i retest it with 11.7 catalyst and yes there is a mouse input lag.
even if tearfree is off and Vsinc is off and 3D desktop is off. and so one.
I play hon with the radon driver before and now i retest the catalyst 11.6 and whats up the catalyst11.6 do have a mega mouse lag if i take a item with right click and try it to drop it on an allied hero or just on the floor .
also the side scrolling with mouse do have a input lag.
its unbelievable but the radeon is better in gaming because of the faster mouse input and general faster reaction latency.

i think i found the source... the flash gpu acceleration turn my pc into a zombie...
if i disable the gpu acceleration everything runs faster even videos...
the flash 10.3.x in an 64 bit kubuntu is just totally crap!
you need flash 11 when you want to keep composite on with flash.
the firefox5 gpu acceleration also makes mouse input lag...
its really a shame i turn off all GPU accelerations because of mouse input lag.
not its not a FPS drop.. its its a input lag.
the amd catalyst drivers are bugged since 11.5 until 11.7 and probably 11.8 too, because amd gives a shit about linux users.
