I'm running fine on 8.1 laptop with switchable graphics (Intel 4000 & Radeon 7600). It runs with either graphics card, although obvious higher frame rate with the Radeon which has 2Gb of dedicated graphics.

If that doesn't work, suggest you post your config, especially the graphics card details on here so that others may be able to help.
