Im having some FPS issues while gaming with my new laptop. I got an Alienware 15R3 with a GTX 1070, i7-7700hq, and 16 gb of ram. My issue is games run fine when I use a MDP to HDMI to run on an external screen and game, but I travel for work and have to use the built in screen to game frequently and I get really poor fps, for example when I play WoW on an external monitor i get 100-200 fps (depending on location) and in those same areas while playing on the built in monitor I get 15-30 fps. any help would be appreciated. Thanks.
