Stellaris is also almost 10 years old with an engine that is, by admission of the devs, coded into a dead end. They customized an older version of it too much and now they can’t get the performance improvements from the newer engine versions into the game.
They don’t need a new engine, they need to stop calculating every pop every day and start using events to trigger a calculation. E.g. a species modification or changing buildings on a planet.
Stellaris is like one of the most simulation heavy 4X games there is. There’s a limit to how good performance you can get when you’re making a complex simulation like that.
That’s just blatantly false. We’ve even had dev diaries showing they’ve fixed some performance issues, even showing the performance graphs to prove it.
I haven’t played Stellaria in a while, but I don’t remember the performance being bad. If it is it’s not because of any graphical thing that can be improved, but for the same reason Dwarf Fortress runs like shit, i.e. there’s a limit to your CPU power when simulating hundreds of individuals.
The problem with Stellaris is that they simulate every individual even if nothing changed about them. If nothing changes on a planet or species then they shouldn’t recalculate employed pops.
Easy, event driven updates. Populations would all have a flag “should_update” which defaults to false.
When a population update event occurs, like constructing a building on a planet, you mark should_update for all the pops on that planet to be reevaluated.
Unemployed pops would have should_update until they are employed.
Changing a species would should_update for every pop that got gene modded.
Then every day you only run updates for pops with should_update set to true instead of every pop in the galaxy.
Late game performance would be on par with early game because a lot of planets have been forgotten about
In order to reshuffle pops to make sure they’re in the best jobs, there could be a timer per planet, based on things like the size of the planet, time since last migration, etc to trigger a should_update for the whole planet.
It’d be even better to just trigger the updates during the event and completely get rid of the polling loop, but that would require a lot more work in the paradox engine
That’s literally what the game already does. But it can’t have all the effects you believe it should have, because there are a lot of events that can change a modifier that would require a recalculation.
Also marking thing as “should_update” (like you called it here) the way you describe it would cause terrible performance issues. You can’t mark large amount of pops for an employment update, because employment calculations are some of the more expensive ones to do, and doing it for large amounts of individual pops at a time would cause severe lag spikes.
When the community researched the issue back in 21 it definitely seemed like there wasn’t any optimization because the monthly load was consistent and the major slowdowns appeared around pop job computing.
We may have been wrong because we were using profilers and decomps, which can lead to bad assumptions, but that’s what we saw.
Not sure if I trust paradox to let them. Stellaris still runs like shit.

So you’re saying they might not need a new engine and all they have to do is rewrite half of the old one?
I don’t think they’d have to rewrite half. Just the main population update loop. The graphics performance is fine.

I agree, but they’ve promised performance fixes since like 2018 but never actually put any effort into it.
That’s just blatantly false. We’ve even had dev diaries showing they’ve fixed some performance issues, even showing the performance graphs to prove it.
When? I gave up in 2021.
Thats not true at all, there has been incredible improve, particularly with jobs.
Around when? I gave up on waiting in 2021. They promised huge performance increases every year from 17-21 but it got worse with each dlc.
If they actually fixed it then I would love to come back. I miss Stellaris
3.0 and 3.3 were big on optimization iirc.
They also moved to the custodian system which makes stellaris easily the most polished and stable of all of Paradox games

How would you know if nothing changed unless you’re simulating them?

Oh they finally added that? Nice. The community has been asking for event driven since 2019 so it’s nice to know they added it. I’m gonna reinstall
That was always in there, but the degree of optimization varied of course.
When the community researched the issue back in 21 it definitely seemed like there wasn’t any optimization because the monthly load was consistent and the major slowdowns appeared around pop job computing.

Pops ruin it!
Colossi fix it.
