Best practices for optimizing performance on mid- to low-spec PCs in Unreal Engine?

Hi everyone,

I’m currently working on a small project in Unreal Engine, and my main goal is to make it run smoothly on mid- to low-spec PCs. I’ve already tried lowering light quality, disabling reflections, and reducing texture resolution, but the performance still isn’t quite where I want it to be.

I’m wondering — which areas should I prioritize for optimization first? For example, should I focus more on simplifying materials, reducing AI complexity, or adjusting physics settings? Also, has anyone here used profiling tools like Stat Unit or GPU Profiler to pinpoint bottlenecks? If so, could you share your step-by-step process?

Thanks in advance for any advice or tips you can share!

Turn off lumen and used baked lighting. Don’t use nanite or raytracing.
