Problems with After Effects on new setup
Hello!
Friends, I’m having issues with After Effects. I recently upgraded to an i9 9900k, 32GB RAM, and an RTX 3090. I opened a project from my old computer and honestly, I didn’t notice any performance improvement at all (even in quarter resolution). In fact, my old machine (i5, 16GB RAM, GTX 1650) ran the same project faster—the viewport feels more responsive on the old setup, which really shocked me. What could be the reason? I’m running AE 2025 on both systems. The only difference is that my old PC has Windows 10, and the new one is running Windows 11.

Hey Roman,
Without knowing your project and the size of it, it is difficult to advice on it.
However: I recently found that Windows 11 PRO, NVidia drivers and Adobe was a lethal combination that killed my PC.
In computer terms, you are much better off, than what you had on your old PC. But not enough to make full use of AE v25.
I would like to see 64GB RAM and a fast SSD drive for starters.In terms of rendering, the Intel 9900 chip is 5 years old – not sure about you RTX card.
Again, it depends on the size of your project and what is in the timeline.
Without breaking the bank, can you increase to 64GB memory. Hopefully that is half the problem.
Other people around here are much smarter than me and can recommend rendering and preview settings to optimize your setup.

it seems that you didn’t setup your drivers correctly or the resolution is very heavy or the files are read of an external slow drive, or all these things together. if you want we can hop on a session to see this in detail and we find out the reason why you have this annoying issue.

Mads, thanks for your reply! Especially for sharing your experience with Windows 11.

Hello John!
As for the project itself, I wouldn’t say it’s particularly heavy—it’s 1920×1080, with 3D shape layers, few light sources, and a few deep glows. Of course it was heavy for my old PC, but for new one((Here’s what came to my mind. I’m currently using the NVIDIA Game Ready driver—maybe I should try switching to the Studio driver?
Another thing—I have two SSDs: one for Windows, and one for my projects. After Effects is installed on the Windows SSD, but the cache is set to the second drive. Maybe this is causing the problem? On my previous computer, everything was on a single drive, which led to running out of memory. -
to do the test of the tests: turn off your new pc, remove the system ssd, install your old windows 10 ssd instead, see if the performance is still bad even with exactly your old installation but on the new hardware, let me know after that

Hello, John. Unfortunately, my 3090 died during testing. So, I might be able to find out what the issue is once it gets repaired—if there’s anything left to repair, of course. Thanks for your replies!

Hey Roman,
Sorry to hear this.
Hopefully your RTX 3090 is still under warranty.
Or, that it can be repaired.Fingers crossed.
