[supprimé]
Bonjour,
J'ai un petit probleme sur l'acceleration 3D avec ati 9200:
j'obtien un resultat pas terrible du tout:
[pqcuong@localhost pqcuong]$ glxgears
285 frames in 5.0 seconds = 57.000 FPS
297 frames in 5.0 seconds = 59.400 FPS
294 frames in 5.0 seconds = 58.800 FPS
296 frames in 5.0 seconds = 59.200 FPS
297 frames in 5.0 seconds = 59.400 FPS
297 frames in 5.0 seconds = 59.400 FPS
297 frames in 5.0 seconds = 59.400 FPS
297 frames in 5.0 seconds = 59.400 FPS
297 frames in 5.0 seconds = 59.400 FPS
[pqcuong@localhost pqcuong]$ lsmod | grep fglrx
fglrx 223292 9
[pqcuong@localhost pqcuong]$ glxinfo | grep direct
direct rendering: Yes
j'ai procédé de regarder mon xorg.conf, il me parait bien configuré:
...................

pourriez me dire pk ca ne marche pas mon Acceleration 3D ?

Ce n'est pas sûr que ton accélération matérielle ne fonctionne pas.
En effet, il semblerait que la synchronization verticale soit activée (ie: FPS = Taux de rafraichissement de ton écran) ce qui n'est pas forcément une mauvaise chose en fait puisque la qualité des jeux sera légèrement meilleure.
Le plus simple est que tu testes avec un jeu 3d récent (exemples : GLtron/Neverball/Nexuiz) pour savoir vraiment si oui ou non ton accélération 3d est bien activée.
Au fait que renvoie glxinfo ? (c'est aussi un très bon moyen de le savoir)
