Visualizing Memory and Garbage Collection in Unity

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.
