Very large number of NPC?

Question

How did you achieve optimization of such a large number of autonomous agents, over 500 units?

I am trying to create a large number of rival cars, but the FPS drops already occur at 60 units. This is due to the complex mathematics in the rival car script. I have tried running each rival in a separate thread, but it didn't help much.

What solutions do you see? Should I rewrite all the complex calculations in the rival car from GD to C++?

Simulate only nearby cars, fake the rest.

Depends on what you're trying to accomplish. Visual effect or real simulation. If you only need a crowd, then Franzen advice is absolutely valid. But if you want a real calculation of each car, then

Yep.

Yeah it really depends what actually needs to happen with those cars. But in my experience people, especially beginners, tend to simulate way too much. A lot can be faked/simplified without anyone noticing the difference. There is a bit of artistry to knowing what and when to fake though.

You should try one of the ecs plugins in asset library, alot of units with shared component logics could benefit from ecs framework, especially performance wish.

Though I am not sure if you really need 499 rivals simultaneously...
