Re: Alienware M17xR3 - ATI Radeon HD 6870M problem
I had some issues with my Radeon 6870m running games fine sometimes and then not fine at all. Screens were choppy and nothing ran smooth. I called Dell and got an awesome rep. We went through and made sure my drivers were the latest which they were. We also flashed the BIOS to make sure everything else was fine. After checking all of that we ran a benchmark and discoverd the issue. In order the the M17X to run on high GPU you must have the battery adapter plugged in so the computer constantly has enough power to push the GPU. I really hope this helps becuase I searched for months without an answer.
