10.1 Optimizing Game Performance

This module focuses on finalizing your game for distribution, including optimizing performance, preparing for various platforms, and creating builds. You’ll also gain an introduction to publishing your game on platforms such as app stores or Steam.

10.1 Optimizing Game Performance

Optimizing your game ensures smooth performance, shorter load times, and better frame rates, especially on less powerful devices.

Step 1: Reducing Load Times

• Texture Compression: Compress textures in Unity’s Inspector under the Texture Import Settings.
• Asset Bundling: Use Unity’s Addressable Assets System to load assets dynamically.

Step 2: Improving Frame Rates

Object Pooling: Reuse objects like bullets or enemies instead of instantiating and destroying them repeatedly:

public GameObject prefab;
private Queue<GameObject> pool = new Queue<GameObject>();

public GameObject GetFromPool() {
    if (pool.Count > 0) {
        GameObject obj = pool.Dequeue();
        obj.SetActive(true);
        return obj;
    } else {
        return Instantiate(prefab);
    }
}

LOD (Level of Detail): Reduce the complexity of distant 3D models with Unity’s LOD Group.

Culling: Use Occlusion Culling and frustum culling to avoid rendering unseen objects.

Activity: Optimize a scene by compressing textures, implementing object pooling, and setting up LOD groups.
