How can I optimize my game’s code to prevent excessive CPU usage and reduce the risk of my MacBook overheating during development?

Optimizing Game Code to Prevent CPU Overuse and Overheating on a MacBook

Profile and Analyze Performance

Utilize Unity’s built-in Profiler to identify bottlenecks in your code that lead to high CPU usage. This tool provides insights into per-frame CPU, GPU, and memory usage.

Efficient Script Execution

• Reduce FixedUpdate Calls: Limit the use of FixedUpdate() and consider using Update() for less frequent logic checks.
• Optimize Loops: Avoid nested and unnecessary loops; cache frequently accessed data to minimize costly recalculations.

Graphics and Rendering Optimization

• Level of Detail (LOD): Implement LOD for 3D models to reduce rendering complexity.
• Baked Lighting: Use baked lighting where possible to reduce runtime CPU load.

Efficient Use of Resources

1. Asset Management: Segregate assets by scenes using AssetBundles to ensure only necessary assets are loaded.
2. Pooling: Implement object pooling to reuse objects and minimize instantiation and destruction overhead.

MacBook Specific Solutions

• Thermal Management: Utilize NoteBook FanControl or similar tools to manage fan speed and cooling more effectively.
• Application Settings: Reduce screen brightness and close unnecessary applications to lower overall system load.

Regular Testing and Updates

Frequently test the game on different devices, including high and low-spec MacBooks, to ensure optimal performance and regularly update any third-party plugins to their latest versions.
