Hello everyone,

I have been and on-again off-again Stellaris player since release. I've been back since MegaCorps dropped and I've been playing it heavily, even with all of the current issues and problems. I play the game un-modded; no offence to the content creators out there.

I typically play huge galaxy genocidal types with max AI empires, Devouring Swarm being my favorite playstyle, but I do dabble.

I've had to abandon a couple of recent swarm games around the year 2500-2600 due to performance issues. The lag just gets so bad even on normal/slow speed that I lose interest. I understand that it's mostly my fault for playing 1000 stars with as many AI's as possible, so I'm not complaining here :)

Something I noticed in those games, is that quitting to the main main and then reloading my last ironman save, results in a massive wave of commercial pact notifications in regards to the AI empires. It seems as though they are constantly re-evaluating their choice of commercial pact partners, and the notifications in regards to those changes are 'backing up in the queue' so to speak. Re-logging releases all of them, and it seems to help performance albeit briefly before it starts to get bad again.

Another thought that I had, is that perhaps the galactic market is partially to blame. Even though I cannot participate (who cares what Prey does?), I had a thought that maybe there are hundreds if not more monthly trades being set up by the AI resulting in a ridiculous number of calculations at the start of each month, possibly causing or at least contributing to the major lag at the start of every month?

Just some 'food' for thought (heh, devouring swarm pun).

I do not intend for this to be a negative, bashing style of post. Obviously I'm still playing the heck out of the game in its current state. Just wanted to throw those possible ideas out there.

Take care all, and keep your Prey close :)

Edit - Just wanted to add that I AM playing on the latest steam beta patch and it has not really improved things for me.

I feel a bit like a prick, but the main reason for performance issues was found quite a while ago - number of POPs. There is linear correlation between number of POPs in th galaxy and performance. Trade, wormholes, number of AI and all that doesn't matter, the only thing really matters is number of POPs. When it reaches 3000 - game slows down around 30%. 5000 - Around 50, add another 5000 and loose another 100% of game speed.

All that added code running primarily on one CPU core while the remaining cores are almost idle is IMHO the main problem. If they want to fix the performance issues and make all these new features function properly this needs to change.

When I first got the L-Cluster, my frames dropped to 25 minimum...

Then I killed Dessanu and my frames went up quite a bit.

Not sure exactly what this brings to the table, but bigger fleets = more lag? That should be obvious as it is, especially since the game gets worse and worse as the years go on. I wonder how multiplayer games go in this regard...

Pop job allocation is checked daily, quite probably a lot of your lag is due to that.

Do devouring swarms have trade routes? I hear they can crush game speed when you start using gateways.

Under normal circumstances, no Swarms do not have trade routes nor trade. I have however, inherited trade routes from other empires when I invade and eat their pops, and I have had piracy occur as a special event 'due to some genetic defect a number of our drones have gone pirate' or some such thing when I ate 3 planets that were all connected via a single hyperlane. It went away once the planets were fully purged.

I feel a bit like a prick, but the main reason for performance issues was found quite a while ago - number of POPs. There is linear correlation between number of POPs in th galaxy and performance. Trade, wormholes, number of AI and all that doesn't matter, the only thing really matters is number of POPs.

Not being a prick at all. I'm not much of a forum goer these days, and have only been visiting the Stellaris forums since 2.2 in the hopes of seeing news about a new Beta patch. I appreciate the input :)

Log out of game launcher and / or run the exe file from the installed directory with admin, and log out of launcher. Fixed a lot of performance issue for me. The daily tick is still there but barely noticeable.
