Memory Profiler & Project Auditor

Memory Profiler & Project Auditor

To diagnose memory leaks and find project-wide optimization opportunities, Unity provides the Memory Profiler package and the Project Auditor static analysis tool.

Memory Profiler Package

The Memory Profiler package provides a detailed breakdown of native and managed memory allocations:

• Snapshots: Capture a memory snapshot during gameplay to inspect every loaded Texture, Mesh, Audio Clip, and Script class instance.
• Comparing Snapshots: Capture a snapshot at Scene 1, load Scene 2, return to Scene 1, and capture a second snapshot. Comparing the two lets you see which assets failed to unload (indicating a memory leak).
• Managed Memory vs Native Memory: Track C# garbage collector handles vs native memory (textures, audio buffers, meshes).

Project Auditor

Project Auditor is a static analysis tool that scans your entire project for configuration and scripting problems:

• It runs inside the Editor and analyzes code syntax, compiler setups, asset size distribution, and project settings.
• It highlights problematic API calls (such as calling FindObjectOfType inside an Update loop), uncompressed textures, and missing assembly definitions.

TL;DR

• Memory Profiler captures snapshots to track loaded assets and find leaks.
• Compare two snapshots to find objects that remain in RAM after scene changes.
• Project Auditor statically scans the project for suboptimal C# scripts and settings.
• Use auditor results to fix expensive API calls and optimize asset configurations.
