Forcing nVidia PowerMizer Performance Levels
Tuesday, March 18, 2008I’ve recently had opportunity to install Fedora on Dell Precision M4300 laptop. It has pretty powerful nVidia Quadro FX 360M video adapter with 512MB of video memory. However, desktop 3D effects sometimes were not very smooth, especially after some time of inactivity. The first few movements (like cube rotation, dragging windows) seemed to be quite lazy in response for the first few seconds, but later it is getting very smooth. The reason behind that is video adapter’s GPU being stepped down to the lowest performance level after some time of inactivity. Once desktop got busy again – performance level jumped up, and effects were smooth again. Simple as that, and it can be easily monitored via nVidia X Server Settings utility, in PowerMizer section. Of course, there is a solution for that. (more…)
