Most of us professional AE users have machines with quite a lot of RAM these days - mine has 128GB. It is really frustrating when I'm trying to render something, and AE fails due to the 2GB per frame internal memory limit. Using Power Pin in a 32-bit 4K comp will often give this error.
Why does this limit still exist? I know 2GB per frame is a lot of data, but in 2023 we are working on machines that can handle that easily.
