After Effects Not Using More Than 16GB RAM on a 32GB System (AE 2025)

Hello everyone,

I'm experiencing an issue with After Effects 2025 where the software does not use more than 16GB of RAM, even though I have 32GB installed and allocated 27GB in the preferences.

System Specs:

  • CPU: AMD Ryzen 7 7800X3D (8 cores / 16 threads, 4.2 GHz)
  • RAM: 32GB (31.2GB usable)
  • GPU: AMD Radeon RX 7900 XT (20GB VRAM GDDR6)
  • OS: Windows 11 Pro 64-bit

Issue Details:

  • Even when working on heavy compositions, RAM usage never exceeds 16GB in Task Manager.
  • CPU and GPU utilization appear normal while using other Adobe software.
  • The system runs fine, but AE seems bottlenecked and is not using the available RAM efficiently

 

Has anyone else faced this issue or found a fix? Any insights would be greatly appreciated!

Thanks in advance! 😊

    Hello Kevin,

    Thank you for your response. I appreciate the support.

    I only keep the necessary applications open while working. Typically, in addition to After Effects, I have:

    • Brave (web browser) for quick references,
    • G Hub for mouse shortcuts,
    • MSI Center and AMD Adrenalin for hardware monitoring and management.

    My composition is quite demanding, as it contains multiple nested 4K compositions, some of which include 3D elements (set to Advanced 3D). Additionally, I am using several resource-intensive effects and plugins, such as Deep Glow.

    For my Memory & Performance preferences, please refer to the attached screenshots.

    Let me know if you need everything else and thanks again for your help!

    Best,
    Charles P.

    Hello @Charles_Poiraud2371,

    Thanks for the post. Welcome to the forum. Are you running any other processes, web browsers, or applications while running After Effects? Can you tell us more about the composition, effects, and footage you are using? How are your Memory & Performance Preferences set up? Can we have a screenshot? I hope we can help you with a little more information.

     

    Thanks,
    Kevin
