Lightning cost with lumen

[androleocez]

Hello everyone!
Where i can find information about lightning types cost for the Lumen?
I will explain
I am creating a night city street with a lot of light points. And I’m worried that this scene will become too complex for many PCs.
Point light. Rect Light or Spot light - It doesn’t matter for the end result. But in a case i need a lightning strategy to get the best lightning performance

ps. I searched on the internet but didn’t find anything useful. I hope you help.

If you make them stationary ( and bake ), you don’t need to worry about impact. Otherwise, yes, you’ll need to give people the option to reduce lighting complexity.

A good way around the problem is to use emissive meshes for a lot of this. It doesn’t carry the same cost as actual lights.
