A practical collection of Unity optimization techniques, C# examples, and performance guides designed to help developers improve mobile game performance on low-end Android devices.
This repository focuses on common performance bottlenecks such as memory usage, draw calls, garbage collection, object pooling, texture optimization, mobile shaders, frame rate management, and profiling.
This repository covers practical techniques for:
- Improving FPS on low-end Android devices
- Reducing unnecessary memory usage
- Reducing draw calls
- Implementing object pooling
- Optimizing textures and sprites
- Configuring Unity performance settings
- Reducing garbage collection
- Optimizing mobile shaders
- Monitoring frame rate
- Profiling Unity games on real Android devices

Frequently creating and destroying GameObjects can create unnecessary CPU work and garbage collection.
Object pooling allows reusable objects such as bullets, enemies, particles, collectibles, UI elements, and visual effects to be reused instead of constantly instantiated and destroyed.

This repository includes simple scripts for monitoring FPS and applying mobile-friendly performance settings.
These examples can help when testing Unity games on devices with limited CPU, GPU, and memory resources.
Learn about texture resolution, compression, sprite atlases, mipmaps, Read/Write settings, and memory management.
Read the Texture Compression Guide
Learn about batching, material reuse, sprite atlases, UI optimization, transparent objects, and rendering performance.
Read the Draw Call Optimization Guide
Learn practical techniques for reducing memory usage, avoiding unnecessary allocations, caching references, and managing assets.
Read the Memory Optimization Guide
Learn how to reduce shader complexity, overdraw, shadows, transparency, and unnecessary GPU work.
