    GTX 980 = GTX 1060. It gets about 13K in Fire Strike Graphics.

    My issue has come back out of the blue!
    Resetting power plan won't do anything. Reinstalled all gfx drivers, still nothing. Incredibly frustrating

    Try disabling HDR, might be some bug that makes Optimus turn the dGPU on.

    HDR is disabled. When the dGPU comes on, my idle power draw DROPS (see third post)

    I saw that, seems like the dGPU gets stuck in some random power state, and using it and then closing the program that used it fixes the stupid power state.
    If that work around still works, well, its at least a work around.
    See if you dont have any program that is pooling the dGPU for stats, things like Afterburner, GPU-Z, HWInfo and many others will constantly wake up a dGPU and increase power usage.
