Those of you having performance issues (running hot, bad graphics, glitch screens) please manually updated your graphics driver. I was having terrible issues. Then, I uninstalled the driver, and tried running the Intel installation as I did on 8.1. It wouldn't stick. So, I pointed Windows Device Manager to the driver folder, and it forced the install. Ever since, this thing has been giving me tremendous battery life, graphics are buttery smooth, and my screen adjusts auto - not to mention the Surface stopped running at 1000 degrees.
