So far I'm really enjoying the surface 3, much better than the yoga 2 with 8gb of ram. My surface has 4 and still runs much better than that yoga could. Anyway, inside that a new Intel driver foe the 4400 is out. I like to play wasteland 2 which the surface can, with medium settings. I'm wondering if the new driver will help improvements, maybe I can turn shadows on... is it worth the hassle? Will it improve general battery life? Since that seems to be my one and only complaint so far, battery life.
