After Effects slows over time
Hi, my AE (2022) slows down after working on my project for around 30 mins. Most notably, pre-rendered playback would slow from having no lag, to playing for 1-2 secs and then lagging for 2-5 secs.
I have tried resetting my cache and disabling hardware acceleration, but I’m not sure if it helped. Why should I disable hardware acceleration, anyway?
The only other major application I run is Chrome.
Restarting AE doesn’t help. But surprisingly, restarting the computer does. I wonder if there’s a better way than resetting my computer every 30 mins?
Clue 1: I play No Man’s Sky on the same PC, and it also seems to slows down after 2 hours or so. Resetting the PC also fixes it.
Clue 2: Task Manager does not reveal my CPU or RAM being maxed out.
My project is 2160×3840 and deals with a PNG sequence as the base footage.
Specs: Win10 64 bit, Intel i7-10800, GTX 1660Ti, 32GB RAM, 1TB SSD

Hey Mark,
Sounds like you have already investigated.
Only few things that I can think of to suggest are:
1) Is there any other software running in the background, like Firefox or Chrome?
2) Have the Video Driver updated recently?
3) Although not great, neither should be necessary, what happens when you run in a lower resolution like 1920 x 1080 screen size?
4) How much space is left on your SSD?On my PC, I run the paid for version of CCleaner (there is also a free version) https://www.ccleaner.com
Don’t know whether it will help solve your problem, but it does “keep an eye” on old DLL and cookies etc.Atb
