Do you have any information about updated graphics driver for W510?
The current one has Direct3D problems (http://steamcommunity.com/groups/bigpicture/discussions/1/882961406956871092/) as well as major artifacts in OpenGL rendering making it unusable for any Direct3D/OpenGL rendering.
I have tried to find official Intel drivers but they state:
Windows 8 OS graphics drivers for the Intel® Graphics Media Accelerator on the Intel® Atom™ processor Z2760 are only available from your computer manufacturer. Intel does not provide a generic version of the Intel Graphics driver for Intel Atom processor Z2760 based tablets. Refer to information or software from your computer manufacturer for instructions on downloading and installing graphics driver updates.

So, Acer, any good news?
