hello, i currently have a Alien x15 with 1920x1080 screen reso, and in the game when i change to this setting the game seems to be laggy no matter what i lower the graphics too, i shouldnt even have to do this i have a I7 processor, 1gb graphics gard 6GB of ram.

I was wondering if anyone had any suggestion to help me figure out how to get the game running at full screen with the correct resolution to fit the screen without the black streaks along the edges.
