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.
