After Effects 2025 causes 100% RAM and 100% Disk usage immediately on launch
4dc6074293923ae177e5188283c72850.pngI’m experiencing a severe performance issue with After Effects 2025 on Windows:
as soon as I open the program, RAM and Disk usage instantly jump to 100%, even with an empty project.
This happens with:
No project loaded
A blank project
Only one empty composition
Clean installation of AE
No plugins installed (fresh install)
The program becomes unusable and the entire system slows down heavily.
1. Main symptoms
RAM → 95–100% usage immediately
After Effects alone consumes nearly all of my 32 GB RAM
Even without any project, layers, effects, or media
Windows becomes slow after opening AE
Disk → 80–100% usage
Disk usage spikes to the maximum
Stops only after killing Adobe background processes, but RAM remains maxed out
After Effects sometimes locks the NVMe at constant high read/write usage (70–100 MB/s)
2. Adobe background processes involved
These processes reopen automatically even after being closed:
Adobe Dynamic Link Manager 2025
Adobe TeamProjectsLocalHub 2025
Creative Cloud Interprocess Service (32-bit)
However, they do not use much RAM or disk, so they are probably not the direct cause — the main AE process is.
3. Hardware (so it’s NOT a weak PC problem)
32 GB RAM
1 TB NVMe SSD (350 GB free)
Windows 10/11 updated
Latest After Effects 2025
Any basic AE project should run normally on this machine.
4. What I’ve already tried (full checklist)
✔ Full clean reinstall of After Effects
Uninstalled completely
Deleted all leftover folders from:
%appdata%/Adobe/After Effects
%localappdata%/Adobe/After Effects
%appdata%/Adobe/Common
%localappdata%/Adobe/Common
✔ Reset all preferences
✔ Cleared all media cache
✔ Disabled Multi-Frame Rendering
✔ Disabled hardware acceleration
✔ Tried launching with “-nogpu”
AE says the argument is invalid.
✔ Manually set Windows pagefile
Initial: 4096
Max: 16384
Restarted after changes.
✔ Closed all Adobe processes via Task Manager
✔ Clean boot (no external programs running)
✔ Checked for malware / suspicious processes
Nothing unusual detected.
Still the same problem:
RAM instantly hits 100%, Disk stays near 100% until secondary services are manually closed.
