    Hi, i am just wondering why does powerpoint require high performance graphics, and its quite annoying how it drains your battery when you make a presentation for an hour.

    If you connect it to an external display or projector, doing so will force the dGPU, regardless of what you're doing.

    This is because on models with dGPU, the iGPU isn't physically connected to HDMI and TB ports.

    Yep, powerpoint uses the dgpu. OSX activates the dgpu if:

    1. you are using an external monitor
    2. the program invokes certain frameworks that apple decided would work better with a dgpu

    Microsoft decided to use those frameworks for powerpoint. Doesn't seem that word or excel have that issue. Ironically, you could run parallels and powerpoint and not enable the dgpu, even though that roundabout method is much more intensive. Apple could really benefit from giving the option to more heavily favor the igpu.

    Use gfxcardstatus to disable the dGPU.

    Absolutely not.
