The Optimus support on Linux is similar to how it's done on ms windows. (I dual boot for a flight sim) Performance wise, it depends on the GPU. The lowspec one I have is an Intel embedded one. The higher spec is an NVidia GT750. Using glxgears: Without (Intel): 60fps With (NVidia): 90-95 fps -- Joost -- Sent from my Android device with K-9 Mail. Please excuse my brevity.
