Should I enable i5 4570 Graphics + GT 640 Discrete?

[Humanate]

Question,

Is there any performance benefit in enabling the i5 4570 on chip GPU as well as my GeForce GT 640? I use the GT 640 for my display output. If I use the "Inject Intel" feature in Clover, the Intel HD Graphics show up so:



So am I better to have enabled or disabled? I appreciate it may seem a basic question to some, but would appreciate any enlightenment.

1. Do you have AirPlay mirroring when the integrated hd graphics is disabled? If no AirPlay mirroring, then try to enable the integrated graphics and take a look.

2. Play an MP4 movie using QuickTime, see if there is a process called "VTDecoderXPCService" running? If yes, then you don't have hardware accelerated video playback. Try to enable your integrated graphics and take a look.

Ah, OK I see. When I enable integrated graphics I now have AirPlay option. Also yes, I have "VTDecoderXPCService" running when I play mp4 with QuickTime. So it is advantageous to have the integrated graphics enabled.
