X11, Window Managers Ever since its inception, there have been problems with Compiz; people unsatisfied with the direction of the project forked it, then they merged again. Recently, the project, now known as Compiz Fusion, faced other problems, such as multiple branches and a lack of direction. A major reorganisation of the project is supposed to fix all this.

Except that it's dog slow compared to Compiz (at least on my PC: Athlon 64 3500+, GF 6800GT, Fedora 10).


Which Nvidia driver? I had the same problem with all drivers < 180.22. Nvidia has stated themselves that their previous drivers had issues with KDE4.
It's smooth for me (some 7600 geforce or so) but I don't know what compiz is like.

I'm using the most recent driver from RPM Fusion which, as of now, is:
kmod-nvidia-180.25-1.fc10.x86_64

I hope this is the driver bug, because the video playback (in GNOME) is much slower now after recent updates. I'm not sure whether the latest xorg update caused this or if it's the nVidia driver (I don't have time to investigate this now). Regardless, the whole KDE 4.2 seems slow even with Desktop Effects disabled in KWin, which should rather eliminate nVidia bug from the suspected causes.

Seems that KDE (or actually, the latest QT) exposes a number of deficiencies in the nVidia binary driver.
nVidia is aware of this problem and trying to fix it.

You may want to try the InitialPixmapPlacement and GlyphCache settings. [1] (In theory, they are no longer needed, but I'm stilling using them and both 2D and kwin composition seem to be working just fine)
