RTuner

RTuner helps you understand why your scene is slow and fix it quickly.
It analyzes how objects are rendered, highlights costly material and shader setups, and provides tools to reduce unnecessary pass switches, shader variants, and texture overhead.

RTuner is especially useful for indie projects, mobile, web and VR, where rendering efficiency directly affects FPS.

Scene Rendering Analysis

RTuner gathers detailed rendering data for every object in the active scene:

• Shader and material usage
• Render queues and passes
• Material variants and shader keywords
• Geometry contribution

All information is grouped and presented in a clear, structured view, allowing you to quickly detect sources of excessive SetPass Calls and broken batching.

What You Can Do with RTuner

• Find rendering bottlenecks caused by materials, shaders, or variants
• Reduce SetPass Calls by identifying unnecessary shader pass switches
• Batch-edit materials directly from the analyzer
• Quickly switch shaders across the scene to test performance
• Optimize shader variants by reducing unused keywords
• Prepare scenes for mobile and VR rendering constraints
