For some reason even after changing my settings in the nvidia control panel to use the high performance nvidia processor for certain games, my alienware refuses to change graphics card and instead Is running everything on its Inegrated graphics HD 4000. All the solutions I have seen online haven't helped me switch cards and the last thing I haven't done is gone into my BIOS and tried to manually switch it which I am not to sure how to do. I have the 2012 alienware m17, any and all help would be appreciated!
