How to Optimize Performance with Multiple Dynamic Lights in UE5?

Hi everyone,
I’m working on a project in Unreal Engine 5 that involves a lot of dynamic lights in an indoor scene. However, I’m noticing significant FPS drops, especially when all the lights are turned on at once.

I’ve tried using Lumen and disabling Global Illumination for some lights, but the performance gain is still minimal.

I’d really appreciate any advice on the following:

  • What are the best practices for optimizing scenes with many dynamic lights?
  • Would switching from Movable to Stationary or Static lights make a big difference?
  • Are there tools or methods in UE5 to analyze lighting performance specifically?

Thanks in advance!
