Prob carte grap nvidia geforce fx 5200ddr128

Salut à tous

J'ai une problème avec tous les jeux avec ma nouvelle cg , les images sont instables et je diminue l'accélération dans les parametre d'affichage, les images sont nettes mais d'une lenteur impossible de jouer.

pourtant ma c.g est bien reconnu par le bios et aucune erreur n'est signalée.

je vous donne le rappaort :

y à t-il une incompatibilité entre ma cm et ma cg ?
pourtant j'ai lu que mon bus agp bien que x4 etait compatible avec agp x8.

SVP aidé moi les jeux me manque!!!! merci à tous
