i have interesting problem. i have acer v3-471 with windows 7 and all newest drivers from intel. in graphic managment i set eveywhere performance (even on battery). when i start any game o battery it works fine, but if i plug power cord, everything slows down. for example - mafia 2. on battery game works smooth (about 25-30 fps). on power about 10 fps.
anybody knows about what is going on?
I recommend you check the power settings of your laptop with Acer, do a BIOS update, and get the latest graphics driver from Acer at the link below:
