Problem with Ocarina of Time 3D

Ocarina of Time 3D runs fine, but my computer struggles to keep it at around 60fps. Is there a way to downgrade Citra so that it doesn’t eat up my memory and I can do other tasks in tandem such as using a walkthrough without my computer screaming?

I highly doubt RAM is the issue. Citra uses hardly any of it. CPU utilization is another thing though. And, no. If your CPU doesn’t have enough cores for all your tasks, things are gonna bottleck. That’s just how PCs work.
