Fix: Unity Tilemap Renderer Mode Individual Tiles Slow

Static map renders Individual; 8ms per frame. Chunk: 0.8ms.

Use Chunk mode

Static tiles batch as one mesh. 10x render speed.

Or mix per layer

Animated tilemap layer = Individual; static layer = Chunk. Per-layer mode.

Audit per tilemap

Each tilemap: animated? If not, Chunk is the default.

“Render modes have trade-offs. Pick deliberately.”

If your game has tilemaps, default to Chunk. Animated cases switch; baseline is fast.
