KDE4 Performance Tips
Improve Compositing Performance
Disable animations in the oxygen window decoration.
Configure your Desktop > Look&Feel > Appearance > Windows uncheck "Enable Animations"
This will disable the new fade-in glow effect on the window decoration buttons but will give a large boost to compositing performance.
This fixes "choppiness" with desktop effects.
Disable Vsync
Configure your Desktop > Look&Feel > Desktop Effects > Advanced
Uncheck "Use Vsync"
Unchecking this option typically doubles performance at the cost of visual quality
Switch to Xrender.
Configure your Desktop > Look&Feel > Desktop Effects > Advanced
Change “Compositing Type” to Xrender
This will change it to 2D compositing. If this option is checked you only need good
2D acceleration to run Desktop Effects, but It will disable a few effects that require
3D acceleration.
General Performance
Configure your Desktop > Look&Feel > Appearance > Style > Fine Tuning
Change "Graphical Effects" to something of your choice
(Low display resolution and Low CPU is the fastest)
Use graphicssystem raster
Install the package kde4-rasterblaster
if you experience crashing then simply uninstall the package
Turn off animations in the oxygen style
Configure your Desktop > Look&Feel > Appearence > Style > Configure
Uncheck "Enable Animations"
If you have slow gtk apps, then install qtcurve with synaptic and use Gtk-theme
switch2 to change your theme to Qtcurve
Slow scrolling when web browsing in arora, rekonq or konqueror:
add --graphicssystem raster to the end of their command (but before the percent
sign) in the menu editor (Launch the menu editor by Right clicking the PC icon >
Menu Editor)
