Important: The Built-In Render Pipeline is deprecated and will be made obsolete in a future release.
It remains supported, including bug fixes and maintenance, through the full Unity 6.7 LTS lifecycle.
For more information on migration, refer to Migrating from the Built-In Render Pipeline to the Universal Render Pipeline and Render pipeline feature comparison.
This section contains information on understanding and improving rendering performance.
| Page | Description |
|---|---|
| Reduce rendering work on the GPU or CPU | Reduce the amount of rendering on the CPU or the GPU, or increase the rendering frame rate. |
| Optimize mesh rendering using level of detail (LOD) | Information about features that can reduce the number of GPU operations that Unity requires to render distant meshes. |
| Compressing mesh data for optimization | How to compress meshThe main graphics primitive of Unity. Meshes make up a large part of your 3D worlds. Unity supports triangulated or Quadrangulated polygon meshes. Nurbs, Nurms, Subdiv surfaces must be converted to polygons. More info See in Glossary data to reduce its size, which can improve performance. |
| Loading texture and mesh data asynchronously | How Unity loads texture and mesh data at runtime. |
| Collect rendering data | Resources for using the Frame Debugger window and the Frame Timing Manager to check and debug rendering issues. |
| Optimize rendering lots of objects | Techniques for speeding up rendering by reducing the number of drawing commands the CPU sends to the GPU. |
| Graphics performance and profiling in URP | Resources for understanding and improving rendering performance in the Universal Render PipelineA series of operations that take the contents of a Scene, and displays them on a screen. Unity lets you choose from pre-built render pipelines, or write your own. More info See in Glossary (URP). |
| Graphics performance and profiling in the Built-In Render Pipeline | Resources for understanding and improving rendering performance in the Built-In Render Pipeline. |
| Graphics performance and profiling reference | Explore properties and settings in the Frame Debugger window and the Rendering Statistics window. |
