During the creation of an emulator you can choose if you either want Snapshot or Use Host GPU
enabled.
The dialog implies that you can select both options, but if you do,
you get an error message that these options can not be selected together.
If
you select the Snapshot option, the second time
you start the device it is started very fast, because the AVD stores its state
if you close it. If you select Use Host GPU the
AVD uses the graphics card of your host computer directly which makes the
rendering on the emulated device much faster.
