Garbage collection is one of those invisible systems in Unity that quietly affects performance—until it doesn’t. In this video, we’ll make it visible. You’ll learn how to build a real-time memory monitor that shows exactly how much memory your game is using, when the garbage collector runs, and how allocations evolve frame by frame. We’ll also create a lightweight AllocCounter tool to measure allocations in any section of code, giving you both visual and quantitative insight into your game’s memory behavior. By the end, you’ll have a practical tool you can drop into any Unity project.
