Yes, it does for heavy Fusion compositing.

I’ve spent enough time bouncing off out-of-memory errors in Resolve to know. 32GB is fine for basic 4K timelines and a couple of color nodes. But the moment you stack Fusion effects – particles, text, keyframes, multiple comps – Resolve will eat that 32GB for breakfast and ask for more.

Fusion uses RAM for node caches, OpenCL buffers, and undo history. With 32GB, you’re constantly swapping to disk or hitting the ceiling. That’s when Resolve either stutters or just closes without warning. 64GB gives you headroom. You won’t fix every crash – GPU drivers still fight – but the memory-related ones vanish.

If you’re doing serious Fusion work in 4K, don’t think about it. Get 64GB. Future you will not regret it.
