Kingfisher

Kingfisher

By tracing and measuring the vanilla source code and identifying performance bottlenecks, Kingfisher replaces them with more efficient implementations. This makes TPS/FPS gains without side effects possible.

Optimization Results

In a typical test environment, Kingfisher's patches themselves can achieve speedups of 2x ~ 25x. This will not translate as directly to overall TPS, because save states vary and optimization results are hard to generalize. If you are willing to provide a save from a near vanilla late game colony, that will help Kingfisher iterate on its optimization results.

Technical Details

Kingfisher pursues zero runtime overhead, including: - Uses PurePatcher to inject fields and replace methods, avoiding extra call overhead. - Uses Publicizer to expose private fields, avoiding reflection overhead. - A conditionally compiled profiler, excluded from release builds.
