For that particular screensaver, notice that glmatrix starts drawing nothing. 30 seconds after the start there're lots of polygons so after 20 seconds it needs more processing power. It happens exactly the same but the difference is not so big, from 30fps to 24fps, perhaps you didn't enabled DRI acceleration? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
