NVENC is faster with iGPU disabled

  • I just noticed an interesting aspect about NVENC exporting:

    When having both GPUs enabled (GTX 980 TI and iGPU in my i7 8700K) premiere used the iGPU for decoding and the GTX 980 TI for encoding. I expected this would speed everything up ... But it was rather slowing down!

    iGPU + GTX: 155 FPS

    GTX only: 250 FPS

    So if you are having a similar setup try to disable the iGPU when exporting with NVENC. It might be faster!

    Edit: It might be enough to disable Intel GPU decoding in the premiere preferences. No need to disbale it in the BIOS.
