Mais je vois beaucoup de déchirures de chrome, de vidéos, etc ...

Une idée?

Je ne me souviens pas du lien où j'ai obtenu ces paramètres. J'ai également Intel i7-6700 mais j'ai un peu plus récent GTX970M. Après de nombreux essais et erreurs, ces paramètres ont fonctionné pour moi (avec les anciens paramètres commentés):

$ cat /etc/X11/xorg.conf.d/20-nvidia.conf
