Headless Video Accelerators

Headless video accelerators allow you to the full power of your Mac graphics processor without needing a display. When your Mac is operated without a display attached, the GPU isn't activated - meaning it's not operating at full power. So when you access your Mac remotely, the CPU does all the work rendering the user interface. As a result, the interface lags; OS X animation, cursor movement, menu navigation, and typing all suffer, making remote operations a pain.
