Carte graphique pour minecraft

Bonjour,

J'ai eu envie d'essayer ce jeu qui fait fureur, Minecraft mais pb;

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.
