There seems to be a big issue with multi frame rendering when working on larger projects and files.
My system specs:
64GB ddr5 ram
3x NVME ssds (one dedicated to AE cache)
Windows 11 latest updates
AE version 23.3.0 (Build 53)
I have a 6K comp project that I need to render. If multi frame rendering is enabled, AE will eat basically 99% of 64gb ram even though I have it set to reserve 16gb for other applications. And I have it set to reserve 10% of CPU.
When I hit render I see the blue dashed bar spinning, preparing for render. I have task manager open and all I see is ram usage going to 99%, with AE using +50gb of ram (max should be ~45gb). The render hasn't even started yet and after a while the ram usage drops down and AE crashes without any error. Nothing else is running in the background and pretty much System is the next process that uses ~600mb of ram.
I have attached the last crash file (all are the same) and the weirdest thing is it says that it's related to Nvidia drivers. I don't know how it can be related to gpu drivers, it is a new system (2 weeks old) and I have latest studio drivers 531.61. I did a clean uninstall with DDU and Windows at that point installed an older version but the same issue still happened.
And I can't share the project since I'm under NDA but it was mostly just cleanup with a few comped elements. I used 2 plugins, Lockdown & Red Giant's Spot Clone Tracker. But even projects that use none of these plugins were crashing.
So my theory is that because theoretically with a 32 thread cpu I can render 20+ frames, AE will try to store all those 20 frames in memory even though they don't fit, without respecting the memory limits? Or it also tries to fill the gpu memory for all those frames and it doesn't fit either so that's what crashes it in the end? Very weird bug.
