Hello, I believe I am experiencing some trouble with my laptop. I have a Satellite P755 loaded with a NVIDIA GeForce 540M GPU. When I play games on it the games seem eally low qaulity. Can't even run BF3 on medium. I believe that my laptop is using my onboard GPU instead of my dedicated. I was told my 540M can deffinitly perform well and I honestly have not seen it so far. So this leads me to believe that Iv been using the onboard. Tips/help/advice. Thanks!
