Can this be optimized?

can i optimize this somehow?

That’s a broad question. Here are some suggestions:

  • Use stationary lights that cast no shadows
  • Reduce dynamic cascading shadows and lights that cast shadows
  • If those are all actors, reduce the number of them that have on tick scripting
  • Use an ambient light solution and make ‘lights’ in your scene just have emissive materials

You can also use the CPU and GPU Profiler to see what parts of your scene take the longest to be processed.

Oh, and make sure all your models have a level of detail.
