[0.16.51] Sudden Performance Troubles

[Hellkeeper]

Hey there,
since yesterday I got massive Client Performance Troubles with one of my Maps (Game is hosted on Headless Linux Server) - and I struggle to find out what's causing the massive Drop in FPS! :-/
Maybe one of you can give me an Hint based on this info?

It's flucuating from 60 FPS down to 5FPS and up again (unregular)

You should upload your save-game + logs.

It's the standard "falling behind the server" issue, see the FAQ.

[Hellkeeper]

Loewchen - you nailed it ... it's excactly the "falling behind Server Problem" ... thx!
Sometimes I need to go to Game Speed 0.65 - not fun

Even i'm a bit puzzled WHY this is happening - Task Manager shows that no CPU Core is maxed out (70-80% max Single-Core usage), enough free Memory, GPU usage is ~10-20% ...
Any chances to debug this further to find the "source" of this Problem? Would be a real pitty if we had to ditch this World because of those Performance Problems

thx, bye from sunny Austria

Have you tried lowering Atlas Texture Size ?
(And generally lowering various graphic settings...)

[Hellkeeper]

Hey BlueTemplar.

currently I'm running with those Settings:

Will test Atlas Size later ...

Already killed all Enemies in sight - brought Game-Speed back up to ~0,75-0,80 instead of ~0,65-0,70
But still not where I want to be ...

[BlueTemplar]

English would be better

Come on, you don't have the exact positions of everything in the graphics menu memorized?

[Hellkeeper]

tried with smaller Atlas Size - no luck at all ... also tried several other Settings ... all without any luck ... :-/
After testwise deleting the Main Bus ... well ... of course it went back up to 60 FPS/UPS ... but it's not really purposeful to play Factorio without Bus ...

Well looking at the first screenshot you posted in the OP, the game update part of the tick is taking around 15.24 ms. In order to run at 60 UPS, your computer needs to finish this in less than 16.66ms (less once you consider that rendering also takes time, and cpu cycles).

So no matter how much effort you put into optimising rendering, what you really need to do move to a more ups efficient base design. I would start thinking about what active entities you can reduce (eg inserters, assemblers, pipes, belts, etc). That is part of why people move to a beacon + module base, because that allows them to increase production without increasing the number of active entities. It is also why people move from nuclear to solar, since solar is essentially free from a UPS perspective, whilst nuclear needs on lots of pipes and heat pipes which use lots of cpu cycles every tick.

Do you have any good sources for ups-efficent base building / planning?

There are dozens of Gameplay Help topics about this. Generally: Use beacons and use trains over bots or belts, clear biter spawners beyond pollution range.
