Highlights
- Added Crowd ULTRA and adjustable 1:N display modes for armies with thousands of units.
- Added friendly Physics2D collision and transform-sync optimizations.
- Hidden units no longer render their bodies, particles, floating text, or buff icons.
- Hidden-unit BuffSlot objects are recycled to reduce visual object-pool memory growth.
- Preserves real unit combat, movement, damage, stats, buffs, and save data.
- Removed the old embedded before/after GIF; the full YouTube comparison remains linked in the README.
Controls
- F6: toggle core optimization.
- F7: cycle
ULTRA -> Crowd 1:N -> OFF -> ULTRA. - F8: increase the display ratio by 10.
- F9: decrease the display ratio by 10, minimum 1:10.
For armies with thousands of units, keep the optimizer enabled and use Crowd ULTRA.
Known Limitation
Ratropolis is a 32-bit game. Very large saves may still pause during synchronous autosaving because the game serializes every unit and buff on the main thread.
