[2.0.13] Performance drops when placing belts to long belt reader (drop/UPS/FPS/bad)

[fonn]

I am experiencing FPS/UPS issues when placing a belt connected to the circuit network with the condition Hold(all Belts) true. The whole belt is ca. 5k tiles long. And i experienced having that issue after around 4k belts placed.
I am running a 7800x3d CPU and a 7800xt GPU + 6000hz 32gb ddr5 ram, so hardware shouldnt be the issue.
Im am currently only on blue science with 60spm

It also happens when rotating a connected belt a lot. Tried placing belts while disabling the read items circuit condition, zero lag is caused.
So the condition to read what items are on the belt is causing this.

Welcome to the megabase stage of the game : you cannot ignore UPS limits any more.

BTW, this feature got optimized... but I guess not in the case of a single loooongbelt ?

It could be, but it wonders me that nobody else has run into this issue, I culdnt find a single bug-report about it.

Yeah I think I schould scale down to like 1 spm

I also had this issue when I was using a few thousand long belt with read belt contents - hold (all), plus it caused the game to stutter every several seconds. Though I assumed it's not a bug per se, but an issue of scale. If it could be optimised to work with long belts I'd be happy, but I'm not gonna hold my breath for it.

Thanks for the report. This is not a bug but a simple limitation of the feature. It's cost is O(N) on the number of belts and as you keep adding/changing/removing them from the large belt you get to experience it over and over again.

I am curious, for those that do this - what is the actual value of having a reader on such a long belt?

I've tried using it with an automatic defence wall around my entire base. It read if the belt had enough ammo altogether, so it could put more ammo on the belt if needed without filling the entire belt lane. There's a ton of better designs and different solutions for this, but it was a fun one to try out.

I also just wanted to have a single belt around my base for ammo. Thought with the new feature it would be cool to just read the contents.
