How to Turn on GPU Acceleration Premiere Pro?

Premiere Pro uses GPU Acceleration for rendering or playback. Otherwise, you can cause higher render duration and heavy playback.

To activate GPU Acceleration, you can click on File> Projects Settings > General and check for "Renderer" and then "Video Rendering and Playback." you should choose "Mercury Playback Engine GPU Acceleration." afterward.

Mac has two options: Open CL and Metal. Try both and decide the best for your system. You should avoid "Mercury Playback Engine Software."

Why is Premiere Pro so laggy?

Premiere Pro has a huge file size, and the requirements to download Premiere pro may be high for some computers, so it may cause some lag if your computer specifications don't match it. Also, your computer's RAM plays a big role in it, and problems caused by insufficient RAM aren't easy to fix apart from upgrading it. We recommend at least 8GB of RAM for modern versions of Premiere Pro, but you can still use Premiere Pro on 4GB RAM devices if you install older, less resource-intensive versions.

There are four ways that you can reduce the lag issues.

1- Turn on GPU Acceleration

While making the project's settings, make sure you set the Renderer to GPU Acceleration. If it's grey colored, that may show that you need to update your graphics card drivers.

2- Lower Playback Resolution

If you lower the Playback Resolution, it'll make a huge difference to decrease the lag problems. You can adjust it to 1/2 or 1/4 on the Preview Window settings. Also, you can avoid the lags by making the High-Quality Playback disabled.

3- Clean Up Media Cache Files

Old media files can cause a lag. Delete the unused files to prevent slowing. Programs such as CCleaner come in handy for that purpose.

4- Save Cache Files to a Secondary SSD

For the best performance, the last thing that we can advise you is to save your cache files to another SSD. It's very beneficial to increase the computer's performance for Premiere Pro. This even could be an external drive if you're not able to add another internal SSD to your hardware.
