Hello everyone, thank you for taking the time to read about my issue!I have had a problem that has been a pain in my backside for years now, that is Starsector starting to stutter manifesting as consistent framerate drops every 2 seconds from 60 fps down to as much as half of that, depending on the number of ships in my fleet, before the framerate goes instantly back up to 60.
- The issue appears right from the start, by the time the first loading ends, provided i have a number of ships in my fleet.
- The issue is present all over the campaign layer only, the battles are extremely smooth, locked a 60 fps, even at battlesize 600.
- There is no difference in stuttering intensity or timing whether in system or hyperspace.
- It seems unrelated to whatever is equipped on the ships themselves, guns or hullmods, as the issue present itself even with a full fleet of empty hulls. Furthermore, i can reliably reduce the intensity of the fps drops by reducing the number of ships in the fleet without having to reload a save, down to no noticable stutters with only a single flagship left.
- During the playthrough, it seems that every spike and stutter correspond to new missions intel being displayed on the campaign layer (on the left side of the screen), but that may be in my head.
- Speeding up the campaign layer reduces the delay between stutters, but do not make the framerate drop further; and pausing the campaign layer locks the framerate back up to 60fps.
- The issue persist no matter the amount of RAM dedicated in VMPARAMS (tested on 3,4,6 & 8GB), MezoTronik's, Winka & Shenandoah VMPARAMS & Java versions, across the board.
- No tweaking of VSYNC, Nvidia CP, or Library Mods seems to influence it after VERY extensive testing.
- Reducing the number of factions mods down do not influence it, nor does changing the sector procgen method, as Adjusted Sector, RAT & vanilla procgen all result in the same stuttering.
Here are my computer specs & Starsector launch parameters :
- CPU - Intel Core i7-8700K (12 cores at 3.70GHz)
- GPU - GeForce 1080TI (11GB VRAM)

VisualVM graphs :Here's a typical modded playthrough, with a 20 ships fleet, running laps around the star of a 4 markets system :
- Here's the same exact save, with the same exact fleet but fresh ships with no hullmods, captains or guns:It seems that i have better performance here, but no, about the same amount of stuttering.
Here's the same exact save as the first shown, but i've deleted all ships save the flagship, still with hullmods, guns & captain, so only 1 left:And for reference, here's what a JRE8 unmodded game looks like on my rig:And what my computer looks like at idle :
Now, i am not expecting for a quick fix, but at least some answers, like "Do the used heap on an unmodded game really supposed to look like that?", at this point i feel like i tried everything, but i'm still open to suggestions.
I wish all of you that made it this far to have a great sunday, and i await your input on this..!
EDIT : I apologize for the grammar, english isn't my first language.
