Loading time is extremely slow with ~450k buildings
Done • Priority: Highest • Fix: 4 - Early Access • Game: 0.0.0-alpha22.4 • Resolution: Done

Loading time for savefiles with approximately 450,000 structures is extremely slow, taking around 4-5 minutes to complete. The performance issue was suspected to be caused by quadratic scaling in the loading algorithm. This significantly impacts players with large factories, making the game difficult to access. The issue has been verified and fixed, with loading time improved by roughly 40% through linear scaling optimization.

Improve Blueprint Placement Performance
Done • Priority: Critical • Fix: 1.0 Release [1.0.0]

Dragging a large blueprint (close to 350 machines) causes FPS to drop to around 10, especially when fluid machines are involved. This occurs on minimum graphics settings and above in any game mode and scenario. The root cause is that during blueprint placement, the game simultaneously computes shape previews, checks placement rules, renders the blueprint, and updates the placement map layout, with the placement logic being slow and generating excessive garbage. The proposed fix involves refac...

Holding blueprints severely affects performance
Done • Priority: Critical • Fix: 1.0 Release [1.0.0] • Resolution: Won't Fix

When holding large Blueprints in Classic Mode, the game experiences severe performance drops with decreased frame rate and increased frame time. This occurs even on high-end systems when holding Blueprints containing either 1000 1x1 Space Platforms or 20 Space Platforms with 588 Half Cutters each. The performance impact is considered disproportionately severe for the number of Structures involved. The issue was closed as Won't Fix, with acknowledgment that large-scale Blueprint placement is n...

Savegame serialization is extremely slow
Done • Priority: Critical • Fix: 1.0 Bugfixes before Feature Freeze • Resolution: Done

Savegame serialization is extremely slow when there are more than 100,000 structures placed in the game. The serialization process takes over 1 second to complete with this many buildings. The issue was tested across multiple game versions including 0.0.9, 0.1.1, and 1.0.0-alpha1, with version 0.0.9 showing the best performance. Testing was requested to gather more data on the exact serialization times with large numbers of buildings to assess the severity of the performance degradation.

Performance drops when placing larger island blueprints
To Do • Priority: Low • Fix: None • Game: 10.53.04

Performance significantly drops when placing large blueprints containing multiple Space Platforms. The issue occurs when selecting and click-dragging blueprints with several Space Platforms across the map. Placement animations slow down severely and the game becomes unresponsive, sometimes freezing completely in both the application and Unity. The problem is particularly noticeable with larger factory blueprints and may require optimization work.

Building conflicts can cause significant lag
Done • Priority: High • Fix: 4 - Early Access • Game: 0.0.0-alpha23 • Resolution: Done

When there are a large number of Structure conflicts, significant lag occurs. The issue is triggered when copying and pasting large amounts of Structures, particularly when copying entire Space Platform contents. The lag happens because the game calculates conflicts between all overlapping Structures, even though a simpler approach of just checking if Structures exist at the same time could be used. The performance issue is noticeable with hundreds of thousands of Structures, and occurs regar...

Do you have a huge blueprint I can test?

Tested with a smaller blueprint so it completes.

ALPHA5: Just under 5 minutes. 0.1.1: 38 seconds.

ALPHA4: Just under 5 minutes.

ALPHA3: 38 seconds.

[trail crown]

ALPHA3 still has the exponential relationship between building count and paste time however. But it's a lot less than A4/A5.

Attempting to get to the bottom of this one right now.

Can you reproduce it?

[oak tendon]

I reduced your blueprint down to 82.6k and then did two videos showing 011 vs our latest internal build.
