After playing for a while, the FPS-lows suddenly starts tanking, this is especially evident when the camera is moving, as even though the average frame rate is fine, ~110 or so, it is very choppy. It is hard to record it, but I tried to record at 120 fps and it think it shows up a little bit.

Mono RAM continuously climbs then periodically drops, causing severe low 0.1% fps events
To Do • Priority: High • Fix: None

Mono RAM continuously climbs over time and then periodically drops sharply, causing severe low 0.1% fps events. This can be observed by enabling debug charts and the performance chart legend, then waiting for the cycle to occur. The repeated pattern suggests a hidden garbage collection event is being triggered when memory reaches a threshold. The expected behavior is that Mono RAM remains stable without forcing garbage collection, avoiding the associated performance hitches.

Console errors when leaving game
Done • Priority: Medium • Fix: OLD Early Access • Resolution: Won't Fix

A player on Alpha 15.2 encountered console errors when using the save and leave function after starting a new save file. The error log shows a savegame version mismatch where the background savegame version was below the minimum supported version, event unregister failures during HUD disposal, and DOTween animation callback errors. The errors appeared in the console but did not cause actual gameplay issues or prevent the game from functioning. The issue could not be reproduced by developers, ...

<color=#0099bc><b>DOTWEEN ► </b></color>Target or field is missing/null () ►
Done • Priority: Critical • Fix: None • Game: 0.0.9-rc7 • Resolution: Done

Game crashes when attempting to load a Hexagonal scenario Savegame on Linux and Windows. The crash is triggered by a missing Shape definition for ShapeId #1478 ('CuCuCu--') which causes game initialization to fail. This results in DOTween animation callback errors as UI tweens attempt to execute against an uninitialized game state. The issue was reported fixed in Steam version 0.1.1 where the Savegame loads successfully without crashes or errors.

[0.0.9-rc1] Camera jerks, low fps every few seconds
Done • Priority: High • Fix: Version 0.0.9 • Game: 0.0.9-rc1 • Resolution: Cannot Reproduce

After starting a new savegame and enabling cheats, moving the camera around causes periodic freezing or low FPS every few seconds. Disabling "Parallel Rendering" in graphics settings appears to fix the issue. Multiple players have reported similar experiences, though the issue is not consistently reproducible on QA systems. The development team has identified several spike sources including TranslucentImage.Start, HUDIslandSelectionDetails, and HUDInteractionZoomManager, but no clear dependen...

Lower spec machines are having consistent stutters for larger save files
Done • Priority: Highest • Fix: 1.0.0 Release • Game: 1.0.0-A3-A5 • Resolution: Fix Verified

Large savegames with high structure counts cause consistent stuttering and momentary pauses on lower-spec systems. This is triggered by a reactive simulation slowdown mechanism that reduces simulation speed to maintain ~30 FPS when the system cannot handle the savegame size. While it achieves a relatively stable average frame rate, the non-adaptive implementation produces highly unstable frame times, resulting in visible regular hitches in gameplay. Higher-spec systems show no stuttering even...

Massive performance issues (possibly due to fluid predictions)
Done • Priority: Highest • Fix: 4 - Early Access • Resolution: Done

The game experiences severe performance issues including massive lag, FPS drops, and complete freezing that occurs suddenly during gameplay. The issue appears to be related to fluid Shape Previews on Conveyor Belts. The performance degradation is so severe it makes the game uncomfortable or unplayable. Multiple users have reported this same issue. A temporary workaround exists by switching to simple prediction mode, though this reduces the accuracy of fluid predictions.

Based on the description it sounds like something that should happen repeatedly. This happens once, the fps craters and stays that way until the game is closed. I will check out the debug menu you are referring to when I next get a chance to ASsalute

I think I have figured out the cause of this. It seems to be a known issue with using gamescope, as seen here: https://github.com/ValveSoftware/gamescope/issues/697#issuecomment-2564875728
If I run the game without gamescope then the 30-40 minute framedrop does not occur.
Sorry for wasting your time when it wasn't even an issue with the game itself :D
