Watch Dogs à cesser de fonctionner écran de démarrage

salut tt l'monde !
pour ma part, j'ai eu ce problème et j'ai galéré longtemps avant de trouver
sachant que ma carte graphique est la hd 6990 (bi-gpu), j'ai cherché un fix sur internet. le mieux à faire, c'est Google, taper : "FIX [le nom de votre carte] Watch dogs] puis faire comme suit :
il faut aller modifier le "gamerprofile" dans :
C:Users<Name>DocumentsMy GamesWatch_DogsRLD!GamerProfile.xml
copier le texte ci-dessous, et remplacer celui qui est dans "gamerprofile" par celui-ci .... et miracle, ça passe ! je ne sais pas si ce "fix" peut jouer pour les autres crossfire et bi-gpu ....
il suffit ensuite d'aller tout remonter dans les options ;-))))
