AE 2023 performance issue

Hi @JohnColombo17100380 ,

Thanks a lot for the fix!

I've tested again (on 25.2.0.30), and unfortunately there are still some issues.

- Deselecting a lot of layers is now as fast as in AE 2021, so this specific issue has been fixed. I've noticed that clicking an empty space in the timeline is MUCH faster than clicking an empty space in the comp/viewport. That makes sense as in the timeline there's no need to check if some layers are available under the mouse cursor.

BUT

- Now, selecting all layers is VERY slow (I mean, using the Ctrl + A shortcut), it takes several seconds to select my 50 layers.
- Another strange issue : if lots of layers are selected, the menus take at least a couple of seconds to pop up (File/Edit/Composition menus, etc). I noticed this trying to open the about dialog to check the exact version of After Effects 😉
- Even revealing a property with a shortcut is a pain (like P, W, S, T etc.)
- I have also noticed that switching the current tool with a keyboard shortcut is much slower (a couple of seconds) than clicking on the tool icon in the toolbar.
- This is only if there are lots of expressions : with my 50 layers selected, adjusting any property for of all of them at once is very, very slow, it makes it almost impossible to drag the value, even if the property being adjusted is not used in any of the expressions.

This all happen if there are a lot of (shape)layers selected. If nothing is selected, things get much better.
Showing or hiding layer handles doesn't change anything.
I have tested with a very simple comp and things begin to be noticeably slow with : a shape layer containing 10 basic rectangles, duplicated 50 times. It's a lot, but it's not a huge comp as we can have sometimes, and still, working with a big selection makes everything very slow, and even just selecting a lot of layers is very slow...

I recommend learning DaVinci Resolve/Fusion. Bit of a learning curve but SO much faster. Possibly not all the features of AE yet, but they'll come and I haven't encountered anything I miss yet. I've already cancelled my personal CC subscription.

After Effects 24.0.1 is dragging and lagging when scrolling in the timeline, or moving keys. Same issues as before are reappearing in this update. 

Updating the graphics driver worked for me too. Please pin this as one solution!

Adrian, I can't speak to the playback and frame drop issues mentioned in this thread, but updating to the latest 2023 helped my situation with moving keyframes and the delays associated with that process. Good Luck!

Hey guys,

any news on this one?
Actually I´ve updated to the newest version, hoping for performance fixes, but its still painful to work with. Will this be fixed? I really cant move a single keyframe without lag on a heavy maschine. Working on our projects is really painfull and our team is waisting a lot of time waiting for AE to respond when a keyframe ist moved.

Our team noticed that more or less every second maschine is having trouble with laggy performance since version 2023.

Really hope this will be fixed asap 🙂

Hi John, 

Problem is coming back again. will try to update now. bit worried if it makes it worse. fingers crossed. will post an update later.

Edit : I activated Vertical sync in Nvidia Panel because all the animations in AE 2023 (and 2022)  were cut in pieces in horizontal without that. 
Anyway with Vertical sync activated or not I have frame drops, I would say 5% to 10% are skipped in 30fps, creating lags, with Mercury or Cuda. Nvidia Studio drivers up to date.
IS a 5 years old RTX card too old for AE ? I hope not...

Timeline is much more responsive since last update, but I still have frame drops in the viewport when playing cached preview. After effects just cannot read a simple square moving from left to right in 30 FPS without skiping frames. This is really annoying. Is it a video card issue, maybe...  I have a Nvidia 2080 on Ryzen 9, it should drop frames like that.
