My project has too many collision boxes, it detects all the time, I remember UE officially released a video about the optimization of collision boxes, using player position optimization, but I’m not sure, I can’t find the original video, can someone tell me? Thank you so much.
I’m not sure, am I mistaken? Isn’t the collision box detected every frame? I want to follow the official method, when close to the collision box, only start to trigger detection, instead of the box in the world scene has been consuming my performance, I looked for half a day and could not find the official video I watched before, thank you for your reply, I will see your method later.
If you spend time watching for the player before turning on the box, it’s worse 
Collision is highly optimized already, just try the pawn setting and you’ll see a huge difference ( if indeed collision is causing the problem ).
Thank you for the answer, I changed 8 collision box detection objects, FPS increased by 1 frame
If you only have 8 boxes, this is not what’s slowing down you game
I don’t know, I’m watching the official video to find the reason, my map it only has 20FPS. I have 2 movable point lights in my scene with an attenuation of 2500., an intensity of 30, and 68 smaller movable point lights or spot lights, maybe I should change their mobility or remove some unnecessary lights.
I didn’t use the TICK node for this map, and I also controlled the material to be below 2K
Doesn’t sound like there’s much of anything in the scene. What’s your machine spec?
Not so good, I310100, GTX1650，WIN10
First step: turn off lumen 
Hi,I didn’t turn on Lumen, I replaced some of the point lights with spot lights and changed their mobility, I was shocked, raised 7 frames, in addition I noticed that hiding lights that were not in the field of view, it seemed that there was no hint for FPS.
