Unity Performance Optimization - General Chapter

1. Unity performance optimization strategy:

1. Rule formulation: The formulation of performance optimization rules needs to be as detailed and comprehensive as possible, including performance indicators of each link, performance optimization methods and tools, etc., so that developers can understand and execute them.
2. Performance monitoring during the development process: Performance optimization should run through the entire development process. It is necessary to monitor the performance of the program in real time, find problems in time and optimize them. This can be achieved by using performance monitoring tools or by writing performance testing code.
3. Code review and optimization: During the development process, the code needs to be reviewed and optimized to ensure the quality and performance of the code. Code inspection can be performed using code static analysis tools to discover potential problems and room for optimization in the code.
4. Performance testing and optimization: After the project is completed, performance testing and optimization are required to find out performance problems and fix them. You can use performance testing tools to stress test programs to find performance problems and bottlenecks and optimize them.
5. Regularly check and update rules: The rules for performance optimization need to be constantly updated and improved to adapt to changes in projects and advances in technology. Rules can be checked and updated periodically to ensure the validity and applicability of the rules.
6. Reasonable allocation of resources: Performance optimization consumes a lot of time and energy, and requires reasonable allocation of development resources. At the same time, factors such as time and cost need to be considered during the optimization process. Therefore, it is necessary to weigh resources and costs in performance optimization to ensure a balance between optimization effects and development efficiency.

In short, performance optimization requires the participation and attention of the whole process, including rule formulation, performance monitoring during development, code review and optimization, performance testing and optimization, etc. At the same time, it is necessary to regularly check and update the rules and allocate resources reasonably to ensure the effect and sustainability of performance optimization.

2. Common modules for Unity performance optimization:

Rendering performance, memory performance, physics performance, script performance and network performance

1. Rendering performance optimization: including reducing Draw Calls, reducing the number of triangles, using LOD, using batch processing technology, reducing real-time light sources and other technologies to improve the frame rate and rendering efficiency of the game.
2. Memory performance optimization: including using object pools, using appropriate textures, using asynchronous loading resources and other technologies to reduce memory usage and improve game fluency.
3. Physical performance optimization: Including using the correct collision detection method, using the best practices of the physics engine, etc., to improve the physics effect and performance of the game.
4. Script performance optimization: Including the use of correct scripting methods, avoiding frequent garbage collection and other technologies to improve the logic processing efficiency and performance of the game.
5. Network performance optimization: Including the use of correct network communication methods, optimizing network data packet transmission and other technologies to improve the networking effect and performance of the game.

Fourth, some tools that can be used for Unity performance optimization:

There are many useful optimization tools, the following are some commonly used tools: 

1. Unity Profiler: Unity Profiler is a performance analysis tool that comes with Unity
2. PerfDog: Monitor the frame rate, memory, CPU usage, etc. of Unity games to locate performance bottlenecks.
3. UWA: UWA provides local detection and cloud detection tools, and you can choose the corresponding tools according to your needs.

In addition to some of the above tools, you can also choose the rest of the tools according to your preferences.

In addition to using tools for performance problem location, there are other solutions that can help locate Unity performance problems, such as:

1. Elimination method: locate the specific cause of the performance problem by gradually eliminating the possibility.
2. Optimization method: Improve game performance by optimizing code, reducing resource load, and modifying rendering settings.
