Enable the pipeline cache that is saved to disk if the graphics API supports it.
[b]Note:[/b] This property is unable to control the pipeline caching the GPU driver itself does. Only turn this off along with deleting the contents of the driver's cache if you wish to simulate the experience a user will get when starting the game for the first time.
