Default Ingame fullscreen

Hello guys! I'm new here.
So, first i will tell you about my device - TF300T, CM11, SnapShot 2.
So, my problem. When i turn Asphalt 8, it is starting in fullscreen. And cause of fullscreen it have SO BAD resolution!
When i have played on 10.2, without fullscreen resolution was great. When i manually used fullscreen on 10.2, i had same problem.
How i can turn off auto fullscreen in CM11 or make good resolution?
