Why does my Aero Theme on Windows 7 64 bit go off sometimes during gaming ? I do alt tab sometimes. It is mainly in Simcity 5 and Battlefield 3. Not so much Left 4 Dead 2.

Aero which is dependant on the WDDM (Windows Display Driver Model) relies on your Graphics card to render the transparent effects of Aero. Due to the performance settings of your computer. and the graphics driver you have installed. The computer might disable DWM (Desktop Window Manager) in order to save resources and use them elsewhere. In this case the game that you are playing.
As far as why it does not come back on when you are done. This could be due to how the graphics driver works as it is not freeing up resources properly.
However, you can turn this feature off.
