-Several popular graphics cards out there - especiall NVIDIA ones - exhibit performance problems with KDE4. These performance hits mostly concern [[Projects/Plasma|Plasma]] - the KDE4 desktop - and [[Projects/KWin|KWin]] - the KDE window-manager. Generally speaking this isn't due to KDE4 being unoptimized but a problem with the cards' graphics drivers. This page encompasses certain problems that might arise and how to get rid of them.

 * For NVIDIA cards there's the free '''nv''' and the proprietary '''nvidia''' driver. While KDE4 should work fine with the former, it doesn't offer 3D acceleration, so the latter may be your only choice. <s>All</s> Most NVIDIA subsections herein only refer to the proprietary driver (there's also a 3rd free driver called ''nouveau'' that's currently being written. Unfortunately I don't know how usable it is so far). Due to licensing restrictions most distributions don't install the proprietary driver by default. Please refer to your distribution for information on how to install it.

 * Setting ''InitialPixmapPlacement'' to 2 might improve plasma's performance but might make kwin hang sometimes.
 * Setting ''OpenGL mode'' to ''Shared Memory'' might make kwin more responsive again.
-(note from a user)* Not selecting "Use Vsync" helped a lot in a gforce 6800
+(note from a user)* Not selecting "Use Vsync" helped a lot in a gforce 6800 (and also on a GeForce 8400M GT).
 If for some reason your Xserver hangs after hitting the ''Apply'' button on the dialog and your settings get reverted because you can't confirm your changes in time, try again. Usually it will be faster on one of the subsequent tries. If it doesn't you can still change your settings in <tt>~/.kde4/share/config/kwinrc</tt>.
