glxgears saccade

Bonjour,

J'ai un petit probleme avec glxgears, quand je tape la commande glxgears -printfps, j'obtiens les chiffres suivants :
51 frames in 5.1 seconds = 10.072 FPS
54 frames in 5.1 seconds = 10.673 FPS
ce qui est assez minable, et laid.......
Et en fait je me suis aperçu que lorsque je déplace une autre fenetre pendant le test, les engrenages sont fluides. (1175 frames in 5.0 seconds = 234.998 FPS)
J'ai le meme probleme pour lire les videos, en fait lorsque je manipule une fenetre en meme temps que je regarde la video, elle est "normale", alors qu'elle est saccadé en temps normal
Quelqu'un aurait il une idée svp ?

Voici mon xorg.conf :

Re : glxgears saccade

j'ai exactement le même problème!
sans rien faire glxgears me donne environ 10fps, mais si je déplace une fenêtre en même temps j'obtiens 2500fps!!
A noter que fgl_glxgears me sort plus de 1000 fps.
J'ai ati mobility x700

Let's sKa!

Re : glxgears saccade

J'ai aussi une X700 ! J'ai également remarqué que lorsque je travaille sur batterie je n'ai plus de problème. Le problème survient uniquement quand je travaille sur secteur... Peut-etre est ce dû a un économiseur... La carte graphique est p-e sur-alimentée !?
