New High End PC / After Effects Timeline / Layer & Keyframe Movement / Major Lag Issues

[chappz180]

[Screen recording of issue has been included with this post]

I recently made the switch from Mac to PC in order to get some more bang for buck and moreso to make my system more upgradeable in the future.

I have been using After Effects almost every day for the past 10+ years, so I have encountered my fair share of bugs and issues (although, always on a Mac) - so what I have encountered this week has really stumped me!

After Effects itself is running great - the only thing I am having trouble with (that I have never seen on a Mac before) is sliding layers and / or keyframes left and right in the timeline and encountering enourmous lag.

-Scrubbing the playhead and actual playback are very smooth, no issues there. It seems to be a UI or Graphics Card issue.

-I have gone and unchecked 'Hardware Accelerate Composition, Layer, and Footage Panels' restarted AE and also my system.

-I have been on Google all afternoon and can only find a few very old posts that are remotely relevant.. Forgive me if this is easily answered!

I'm having the same problem. So annoying. I tried to do a fresh reinstall and cleaned all the database/cache/plugins/extensions, and it still runs horribly.

By chance, I have figured out a temporary workaround! 

- keep the latest version of After Effects on your machine. You are going to need it to backsave some copies from here. 

- Install the previous version from the Adobe cloud app, so that you can run AE 2023 and AE 2022 at the same time.

-The timeline issue is fixed for me on my end, I have actually done a screen recording side by side of this issue, do you know how I can tag Adobe to get this looked at as soon as possible?

I've seen a bit of chatter about this on a Slack; one of the AE team members responded and they appear to be gathering data on what might be causing this, though it doesn't seem too widespread.

That user rolled back NVIDIA drivers and it appeared to fix the issue.

Amazing, thats really helpful to know.

If you have comunication with them, would you be able to ask that person exactly the NVIDIA driver to roll back to? I would rather be on the latest AE version than have to patch it with an older and outdated one.

For anyone following this post, AE version 23.1 contains the laggy timeline bug across all operating systems (Windows 10 and 11, latest Mac OS, I have asked friends and colleagues and everyone is confirming)

Simple fix until Adobe fixes this issue is to revert back to AE Version 23.0, it works great on my system (Windows 11)
