from the threads I posted it should be clear that kde4/qt4 are not the only ones affected. gtk is slow too. So is firefox. On Intel integrated graphics, qt4/kde4 is fast and fluid. That should give someone food for thought. I bought an Ati because I was fed up - and while it is not perfect, it is so much better that I am glad that I did the jump. Using xshm instead of xv for video is a small price, for not having to wait several seconds until the desktop reacts on a right mouse click or have krunner work as soon as it is open. Also the 7300 is a bad example - it is a very slow card. And the big 8 and 9 cards hide some of the slowness because they are so powerfull that it makes up for some of the shitty drivers. The worst part - Nvidia knows about this for ages - and nothing happend.
