So whenever I try to use a blueprint of more than a couple of items, including normal blueprints and cmd-C blueprints, my game slows down - like way down from 60fps rock solid down to 4-5fps. As soon as I place the blueprint and clear it from the cursor, the game speeds back up again.

Is this a common problem that anyone else is having, with a known fix/workaround? If not I'll post more details of mods and stuff.

No, we are not having this, so you should probably show a log and screenshot with debug info (F5) of the performance when it happens.

O yeah this happens to me regularly. I thought it was just how things are.

For you - with that graphics card - it is

It happens on my PC too with the Radeon R9290...

Huge-ass circuit network blueprint is far beyond "a blueprint of more than a couple of items"

That was my reaction exactly, big full screen of stuff and huge cricuit network blueprint over it with not that powerful GPU. When you say "blueprint of more than a couple of items", I imagine like 20 or 30 entities, not this.

I call this not a bug.

Original poster still has not provided additional info, so moving to Pending.

Sorry for the delay.

See below for three screenshots. only difference between them is hitting ctrl-v on a pretty basic furnace stack. Certainly not hundreds of entities all wired together. FPS drops down to around 8 in this situation. I've attached the log too.

Sorry! It turns out it was a mod. Somehow the "single splitter" mod was responsible for it.

The slowdown is in the rendering of the "interaction boxes" because the mod adds an inserter with the properties "pickup_position = {0, 200}, insert_position = {0, 200},".

I didn't try to disable that at first because I wasn't really using it, and there definitely aren't any of the single splitter entities in this blueprint. Does the mod making a 200 unit wide interaction box (which is what I assume you mean) mean that *every* interaction box becomes 200 wide?

We should have limited these distances long time ago, it should never be more than half of the chunk to support some future plans.

O_O

FYI, my "Lane Balancer" mod which is based on single-splitters incorporates this fix. It also improves on single-splitter in multiple ways:
1) supports connecting to undergrounds, splitters, and sideways belts (T-junctions)
2) adds a tier of lane-balancer for each vanilla belt type (yellow, red, & blue)
3) graphics don't get cutoff by adjacent belts.

It otherwise has the same functionality as single-splitter and can be used as a drop-in replacement.
