Скачать или смотреть Isometric RTS Optimization: Frustum Culling With Sector-Based Maps in Unity

Learn how to optimize an isometric RTS in Unity by combining sector-based maps with custom frustum culling for huge performance gains.
In this video, you’ll see how Amine Rehioui splits a large RTS map into sectors, then disables entire groups of GameObjects that fall outside the camera frustum while keeping game logic fully active for all entities.
We’ll break down how to decouple gameplay logic from rendering, why this matters for CPU traversal on very large maps, and how this approach compares to Unity’s built-in culling on complex scenes.
You’ll also learn how to handle special cases like minimap rendering, where culling must be disabled to avoid missing sectors in the overview.
Finally, we’ll look at real performance benefits on big isometric maps and how these ideas are applied in the development of the strategy game Powerplay.
