Arm Unity Optimization Resources
The Unity game engine is a highly popular development environment used to create games and applications across multiple platforms. Arm works closely with Unity, acting as a champion for optimal performance on mobile platforms both through runtime efficiency and profiling. Game developers can use Arm Performance Studio to profile, debug, and optimize games using Unity. Refer to our best practices and sample code for artists and developers to help maximize the performance of mobile games.
Unity Best Practices
These documents provide a getting-started guide with Unity on Android to general best practices for developing on Arm using Unity and some specific best practices for special effects.
Artists' Best Practices for Unity Developers
Optimizing game artwork is essential for getting the most out of Arm GPUs. The following best practices help artists design more performant artwork and calculate reasonable assets budgets for mobile.
Read the following documents to optimize different aspects of your artwork.
- Textures best practice
- Materials and shaders best practice
- Lighting best practice
- Geometry best practice
Arm joinly with Unity created an interactive tutorial on Unity LEARN.
Profiling and Debugging Unity Games
Arm's free performance insight tools help improve Unity game performance. Arm Performance Studio helps game developers quickly find the cause of frame rate drops, and performance bottlenecks, which might slow down the game, drain battery or overheat the device.
- Use Arm Performance Studio to profile and debug your Unity games on mobile platforms.
- For Unity profiler users, Arm provides a Unity package to read and display Arm’s GPU hardware counters.
