If you find that the option is grayed out, check if your hardware permits it and ensure that you have updated drivers. You may also see if DWORD DisableHWAcceleration exists in the following registry key and that it has a value 0.


If it does not exist, create a new DWORD DisableHWAcceleration. A value of 1 disables hardware acceleration. A value of 0 enables hardware acceleration, provided the system meets hardware acceleration requirements.
