Adobe Premiere is not using the GPU when rendering and the rendering process is extremely slow.

Hello everyone,

I'm currently in the process of rendering a 7-minute video. Just to clarify, I'm not utilizing any third-party plugins. The effects applied to the video include Lumetri, Ultra, and Circle, along with some movement effects. According to Media Encoder's estimations, this video rendering process is expected to take approximately 3 hours. This timeframe seems excessive, the video is 4K resolution and I'm exporting using MOV format with an alpha channel.

My main concern is that during the rendering process, my GPU utilization appears to be quite low. I've taken steps to optimize the GPU usage, including activating the CUDA option and adjusting settings to ensure both Premiere and Media Encoder are set for maximum performance with the video cards. Despite these efforts, I have yet to observe any notable improvement in rendering speed.

I'm reaching out for assistance—can someone offer guidance on how to address this issue? Attached, you'll find details about my operating system. As per these specifications, the rendering performance should be significantly better.

Thank you for your help.

I've decided to give the beta version a try based on my positive past experience with video creation. Additionally, the new features seem quite promising. With regard to SLI, I've chosen this approach to make the most of my dual video card setup, aiming to optimize their collaborative efficiency. At present, I'm using MRQ to ensure alpha channel exports for further editing in another software. However, I'm considering removing this step to streamline the process, considering the considerable time investment it currently requires.

You are running two cards, it sounds like in SLI mode?

What are both cards, number & vRAM?

And ... Premiere isn't really optimized to use SLI setups in GPUs, as far as I can recall. Tends to use one card only, I think.

Yes, I'm currently utilizing SLI. I believed it to be a smart choice, leveraging the combined power of the two cards to function as a unified unit. I'm open to your suggestion and intend to disconnect the SLI socket to observe the effects. These two cards are Nvidia Geforce GTX 1080 Ti models.

@RjL190365 is the resident expert on most of the hardware things. Let's see if he pops in. Those are an older card, though they were pretty hot once upon a time.

SLI is the problem. Adobe does not support SLI at all in any of its programs. And if your two GPUs each have 11 GB of VRAM (in the case of your GTX 1080 Ti's) in such a configuration, you do not get 22 GB as both cards' VRAM are used simultaneously, and that what's in the first card's VRAM is entirely copied onto that of the second card. As a result, you will still have only 11 GB of VRAM at most - total - available for use. You do not add up the memory smounts of the two cards together!

And for the record, all other NLEs strongly advise against SLI as well as it can cause problems in video editing programs.

As a result of all that, your available graphics RAM got depleted early in the render/export process, which caused Premiere Pro to get slammed mercilessly into the software-only rendering with absolutely no warning or indication whatsoever, and remained stuck in software-only mode for the remainder of the entire job.
