Porting The Sinking City to Nintendo Switch
summary
Port moves a 2 km^2 open-world Unreal 4.20 game with 33 km of streets from PS4/Xbox/PC to Switch in four months by profiling memory, render and game threads and targeting concrete bottlenecks. Work includes reduced character polygons by ~60% and halved head bones, replacing clothes and hair shaders (disabled cloth saves ~20 ms), creating LODs for everything over 1,000 tris, smaller streaming cells to avoid hitches, and removing reflection captures (≈150 MB front-end memory, ~7 ms render thread). Static NavMesh and clustered GC are added and stabilized.
