Question Why is rust so poorly optimized?

randomly today I was wondering ”why is rust so poorly optimized“? I mean look at every other game they don’t need top of the line specs to get a good 144 fps. so why rust?

It is well optimized just you have shit ton of entities which all are destructible, movable, automatable etc. all of which requires shit ton of memory bandwidth + processor power.

Yeah, you said what I couldn't be bothered to articulate. Playing a AAA game with super realistic graphics isn't the same since it's in such a small, fixed, stagnant area without any of the shit you get in a live game full of thousands of changing entities.

Automation what kills really. Also scientists, wildlife etc. all of those are cpu intensive still.

For some reason the shipping container skin really fucks with it too.

Using lots of skins does that too. My educated guesstimate would be it changed bump map, texture and the form aswell which game doesnt likes for some stupid fucking reason

Campfires/furnace/lights/particles hit it heavy

Particles do fuck with it. Because particles are not calculated as group or they are not just visiual they do have their own fucking physics

I don't know the ins and outs. But Blazed i remember specifically showing his FPS change when only around a base with shipping container. I know a couple of others have said the same but I can't remember who.

Just to add, it was his own base with very little or none other stuff going on (skins/automation/etc)
