Major memory leak since updating to v25

Question

I have had big performance issues since upgrading to the latest version of Premiere. In preferences I have reserved 39 (out of 64) GB of memory for Premiere, but my Activity Monitor is showing 105+ GB of memory in use by Premiere. The app is running incredibly slowly and is basically unusuable.

My timeline is fairly simple with just three files, although on file is 7gb. I am using a proxy. The project file is 205mb. The program monitor is often unresponsive, and sometimes even blank.

I am running:

- Apple M1 Max

- 64 GB memory

- Version 25.0.0

Is this a known issue? Something I'm doing wrong? Thanks in advance.

A 205MB project file is quite large - I rarely let my projects go over 50mb. Here are a few suggestions to help manage project size and improve performance:Organize using Productions: If your project contains many sequences or large amounts of media, consider breaking it into multiple linked projects using the Productions workflow. This modular approach helps maintain performance and keeps project files manageable.Reduce Warp Stabilizer impact: Extensive use of Warp Stabilizer can greatly increase project file size, as its analysis data is saved within the project. To minimize this:Use Render and Replace to bake the effect into the clip.Alternatively, export stabilized clips and re-import them into your project.
