Hardware Encode (Cuda/openGL) option missing when IGPU disabled.

[calluma33208759]

so I'm not sure if this a a "meant to happen" thing or not, but when i disable the IGPU inside of the BIOS  it removed the hardware acceleration option on both Premier pro and media encoder.

When the IGPU is enabled in bios, it will enable HW acceleration, but will use the IGPU before my GTX 1060 6GB, this is with either the Cuda or openGL option selected.

any ideas as to why this would be as i cant find any thing online to answer this.

Cheers

Guess what? The HW acceleration has absolutely NOTHING to do at all whatsoever with whichever discrete GPU that you have. It supports ONLY the Intel QuickSync feature that can only be had with the iGPU fully enabled. Disabling the iGPU also disables QuickSync, and thus without QuickSync the H.264 and H.265 encoders will be locked to software-only encoding.

so, the mercury engine option does not actually "Use" the dedicated card, unless the IGPU and Quicksync is available? in which case it uses the less capable or less relevant processor when editing, as the Cuda option is selected, or is it only for the encoding portion of the process that the Cuda makes any difference (effects aside)?

It needs quicksync to "access" the dedicated cards hardware in H.264/5 ?

You got that wrong. The CUDA or OpenCL option in MPE refers to rendering certain effects BEFORE the video gets encoded. No Adobe-native encoder uses the discrete GPU at all whatsoever for the actual encoding process.

Also, are you transcoding from an H.264 or H.265 source? Are you exporting to H.264 or H.265? If YES to one or both, then the iGPU will be used heavily no matter what unless you switched to software-only encoding. And I have previously confirmed in my own PC that both the iGPU and the discrete GPU are used simultaneously when I exported a 1080p/30.00 Cineform video to a 1080p/29.97 H.264 file when both HW encoding and CUDA acceleration are enabled.

Also, you might have the MPE renderer in the project settings locked to the MPE software-only mode with no way at all whatsoever to change it. If that's the case, then you may have had a driver installed that's too old for recent versions of Premiere Pro to use for MPE GPU acceleration.

Or, if you have GPU acceleration enabled but your exports still use only the iGPU, then you are most likely exporting to and/or from H.264 or H.265 with exactly the same resolution and framerate with absolutely no GPU-accelerated effects at all whatsoever applied. QuickSync does not work on a discrete GPU at all.

Ok, that... actually makes a lot of sense as i am going from h.264 to h.264.

Cheers for the Help

now i wonder if it is worth overclocking the snot out of the IGPU or not
