After Effects 24.0 EXTREMELY slow

I just updated to 24.5 (Build 52) and the lag got reduced massively. I checked my activity monitor (mac) and it's now using at least 10GB unlike the previous version about 18GB RAM, which was annoying because I'm only doing 2D projects. Hopefully, this goes well!

omgg same my after effects won't stop lagging and its annoying because I can't see the preview as it keeps stopping.. moving forward I think y'all should take away the green line under the timeline as the preview thing because my after effects is completely unusable and I will NOT pay for a software that doesn't work properly. Also you guys should automatically save to files or save it to the account because I had to remake the same edit about 4 - 5 times all because the app is bugging out. Please respond to this message as soon as you can , thank you . 

This is some valuable insight.

It's nice to know you have at least a single guy on it, hoping it's an actual GPU accelerated UI. Having it compete with CPU resources for rendering makes it real spotty.

But for multithreading, i don't consider throwing the same entire process at multiple cores, multithreading. The notable issue is that it's unreliable whether or not the next frame will complete in time because only one core works on it. It's a stutter machine at best, and a luck-based preview at worst. If all the cores (or half, even) could work on the next frame, you would get previews approaching realtime without a GPU- you could get much more reliable frame timing without saying "your cores dictate the chunk size of a render, not the speed".

Of course, some effects will always need CPU or a genius to make them work on GPU and that's alright! But in the UI, please add a little icon of a GPU or CPU so we know which ones won't bog down our systems.

@nubnubbud  Absolutely. It is why we've had a developer full-time on our font system for the past year. There was a lot to clean up from the various new font technologies (e.g. variable fonts) that have come online over the past few years. Still more issues to go but we are working on it.

As to your multi-threaded comment, yes, there was a long period of time where the multi-core CPUs weren't being utilized. But that hasn't been the case since the 2022 release. The latest AMD CPUs combined with Windows 11 and an appropriate amount of RAM can push 192 cores at one time in AE. 

@jenkmeister17177426 Okay but you do understand that the fact some fonts will just slow down everything and maybe cause timeouts or crashes is a significant issue and suggests deeper problems, right?

Nah it's gotten worse. Old school CS3 user here. It got slower even to CS6, by a significant margin, bit it still was usable, and back then rotobrush was more stable when it came out, and the other new features were at least worth it. Then in 2012 they went subscription, and every update since has only been attractive to investors and middle managers. 

Seriously, who else would take "it was a bit of a hack, so we removed multithreading, and didn't replace it" as a decent update?

I have the same issue and I do have to use older versions (2020 best so far) so it runs OK. How is that even possible? Aint it supposed to run faster and smoother with each new version? Or is this a Hallmark for Adobe to do Regression!

And no, its not my Mac fault since I do run very intence simulations on it. 

Hi there, I've been trying to solve this problem for 3 days. And there was an incredible slowness in my file, which only contained a few text and a few graphic shapes. It took me minutes to type something new or move the texts or images. And I couldn't solve the problem in any way. I tried loooots of things believe me. After this comment, I thought of downloading the beta. And now everything seems to be fixed in the beta version. I hope Adobe make a stable version of this asap. By the way, I am a Macbook M1 user and I am using it with the latest Sonoma 14.5.

If you try 24.5 Beta, you should find FauxBold is now working with better performance.
