PerformanceTweaks
Optimization mod for Sailwind: higher FPS and better overall performancePerformance Tweaks
Performance Tweaks optimizes Sailwind and makes it run smoother, most of all in busy ports with your boats moored and shops full of goods. The game updates a lot of things every frame that haven't changed or that nobody is looking at: items lying still, ropes on a moored boat, shop goods on their stalls, cameras that draw nothing. This mod skips that work and picks it up again the moment it matters. Ropes are handled smarter too: distant ones are drawn simplified and the ones out of sight update only a few times a second.
Where you'll notice it
Measured in a capital with several boats moored and a full mod list; your numbers depend on your PC and your mods:
| Tweak | Saves per frame, up to | Helps most |
|---|---|---|
| Skip redundant item updates | ~2 ms | Lots of cargo on your boats |
| Skip unmoved crate contents | ~0.5 ms | Many full crates |
| Freeze idle shop items | ~2.7 ms | Capitals and big markets in daytime, more with mods that add to items |
| Food descriptions on demand | ~0.35 ms and less stutter | Lots of food around |
| Skip unchanged ropes | ~2.5 ms | Several boats nearby and big ships with many ropes |
| Simplify distant ropes | ~1.5 ms | Ports full of boats and big ships with many ropes |
| Pause hidden ropes | ~0.8 ms | Most ropes out of sight |
| Skip sync for sail wind shadows | ~0.7 ms | Under sail, and with boats under sail nearby |
| Dirt camera on demand | ~1 ms | Everywhere |
| Outline cameras on demand | ~0.8 ms | Everywhere |
Together that's several milliseconds in a busy port: at 30 FPS each millisecond saved gives roughly one more frame per second, at 60 FPS roughly four.
