Je n'arrive pas a lancer minecraft

Bonjour,
Je suis sous Windows 8, ordi tout neuf (Toshiba Sattelite L875-139) et je n'arrive pas a lancer minecraft. j'ai le message :

"Bad video card drivers! Minecraft was unable to start because it failed to find an accelerated OpenGL mode. This can usually be fixed by updating the video card drivers."

Jai déjà mis a jour les video card drivers avec l'aide du SAV Toshiba et ca ne change rien..

voici la carte graphique que j'ai :

Qui peut me dire si elle est compatible avec minecraft ?

Sinon mon problement est il lié a Windows 8 ou la carte video AMD Radeon HD 7670M que j'ai ?
Que faire, merci !!

Marie
