Fixing Switchable Graphics on Windows 8 Consumer Preview


If you’re like me, then you must be playing around with the just released Windows 8 Consumer Preview.  Experiencing how awesome as it is, some of you might be noticing a decrease in your battery life or very poor graphics performance. This can probably be because of the switchable graphics you have in your laptop and Windows 8 may not know which one to use unless we install the drivers properly. By default it may use the dedicated graphics all the time and may drain your battery unnecessarily or it may use the integrated graphics and give you a poor performance.

For those you using AMD’s dedicated graphics such as the Radeon and Mobility series, the drivers given by AMD should do the trick for a few of us but still switchable graphics is not getting enabled.  In case you haven’t tried it yet, you can download the drivers here :

For Nvidia Optimus users, the Windows 8 drivers can be downloaded from here, but the forum here says that you have to install them repeatedly until you get them working properly.

If none of these work for you, try uninstalling them, and then try installing the drivers you had with Windows 7 using the Windows 7 Compatibility mode (You can set the compatibility mode in the Properties windows of the installation file).  This fixed the problem for few users.

    I have a TechNet subscription provided by my college, so I have had Windows 8 Professional x64 installed for roughly 3 weeks. I have experienced a number of problems with my ATI Mobility Radeon HD 5650 card. After my first restart, it installed the ATI drivers and everything worked fine. Next restart, it installed the Intel HD graphics and it created 2 separate desktops, one accessible and the other, a black screen. I had to blindly go to this “other desktop” to find the “Screen Resolution” window in order to change the default screen back to the screen that was actually being displayed. After further investigation of the problem, the desktop that was being displayed was being run by the ATI card, and the other was being run with the Intel driver. So, I had one desktop run by ATI and the other Intel! This was very weird indeed. I simply disabled the Intel one so I could use the ATI one all the time: until yesterday. Yesterday, I turn my computer on (HP Pavilion dv6t-3000, i5-450M, 6GB RAM) and it boots and has the screen “on,” but it’s black. Confused, I pressed enter like I normally would to log in, and entered my password. The desktop screen came up. This time, when I went to disable the Intel graphics, my screen went blank, and stayed dark. Now, my desktop was defaulted to Intel and not ATI. This, again, was very troublesome and thought that I might need a new installation because I could not get screen to come back. Eventually, I had too plug in an HDMI cord to my TV, and then the Desktop showed up and I had to undo everything I had done before.

    Has anyone come across this or do I just have a really funky card and configuration going on?

    Yours truly,

    -Dan
