Can you post a screen recording of this? What does your project look like, what resolution is your comp, and what resolution are you previewing at?
I'm assuming you meant 32 GB of RAM, but your GPU is likely not the culprit here. You might not have GPU-acceleration even turned on for the project, but Ae doesn't use it in the same way that Premiere does.
What is your source media and where is it being read from?
Do you have a fast SSD drive that you're caching to?
We need a lot more information to help troubleshoot this.
Thanks for your help and sorry I meant 32GB RAM. I'm getting the problem regardless of the comp size and resolution, and it doesn't seem to matter what the content of the comp is. In the example screen capture I've uploaded I've just created 3 identical shapes with scale keyframes.
You'll see that there's a lag on the first one but the other two are fine, then when the RAM preview loops it's fine on the subsequent plays. Obviously it's only a minor issue but as a professional motion designer it's already been pretty annoying when I've never had any similar issues in the past.
I'm running AE off a fast SSD on C: and projects from another SSD, however I've tried saving on both drives and caching from both with the same result, but for such a lightweight scene I'd assume the speed of the drives wouldn't even come in to play.
I've tried turning off GPU acceleration and as you predicted it's not the culprit.
Here's a list of my hardware if this helps
Thanks for posting that, I see what you mean now. You're right, that lightweight scene wouldn't even choke on a spinning hard drive.
It seems unlikely, but I would try updating your GPU drivers. Even without GPU acceleration enabled, bad drivers can still cause funky things to happen.
Threadripper doesn't have an on-board GPU, so you can't take it out of the equation.
Are you running the latest update of CC 2018? There was a patch released last month.

Thanks for for the reply. The computer is only a couple of weeks old so I've got the latest version of AE installed. I also just tried uninstalling and reinstalling my graphics card drivers but still no luck.
No other programs seem to be having issues and Premiere runs perfectly on playback.
I've got a few plugins and UI scripts that I'm using but it's the same as on my old computer so I doubt that would be the issue.
Do you have any other ideas or tests I can do? Let me know if you need any additional info.
Creating a fresh user account is always a good troubleshooting step. It eliminates most customisation you've done. Also, don't sync your preferences. Additionally, you can try trashing your preferences. Weird things can happen when those get corrupted
I've just tried removing all syncing and clearing preferences but no luck. I tried to log in with a different Adobe account but it said authentication failed so I assume this is because I haven't purchased AE with this other account?
I also tried creating a new Windows user account and after logging in to this account and running AE I still had the same problem.
Finally I tried uninstalling and reinstalling AE and removing all 3rd party plugins and scripts but this didn't work either.
I'm wondering if this may be a hardware incompatibility? Perhaps with the type of RAM or config? Can any changes be made here which may fix the problem?
I've also used trapcode particular for the first time and while it renders fine there's a very long lag when changing any of the settings. I'm wondering if this is related? Perhaps there's an incompatibility with Threadripper?

I don't think your Threadripper is the problem here (although anything's still possible).
Unfortunately, I'm all out of suggestions on this one. It's worth filing a bug though and providing as much detail as possible, including your machine specs.
After trying absolutely everything I thought I'd try a fresh install of Windows at it worked! It's a new computer but perhaps the guys who built and installed it put something on that conflicted with it or there was just some sort of bug. It's a hassle as I now need to set up everything again but I would recommend anyone else having the same problem to do the same as a last resort.
Thanks for all of your help and I'm glad it's not the hardware or AE in the end.
Well that's a shame that you had to do it, but I agree, at least this one wasn't caused by Ae or your new machine.
