i try a lot of driver a lot of option ans is still dont work. only the principal gpu work !! what the problem? on the other game that work.
sounds like bf4 xml file is corrupt . go to documents \bf4 \xml folder and delte that . this saves the graphics settings .once you launch bf4 again it will make a new file and you will need to set your display settings again .
merci sa fonctionne j'ai travaillé près de 6 heure pour un problème aussi simple lolll merci.
you're welcome and glad to hear its working good for you .
