Default Re: 8400M GS : Low performences

theophane,
PowerMizer will raise the GPU clocks to maximum performance levels when an OpenGL application is started, but will reduce the performance level again to conserve battery power and reduce heat output if the GPU is being under-utilized. Compiz spends long periods of time idle, so the GPU ends up in its lowest power state. It may be possible to add an option to force the GPU into maximum performance mode all the time, but there will be a tradeoff with increased power usage. By continuously running nvidia-settings, you're forcing the GPU to stay in maximum performance mode all the time.
