Summary - Performance

Reinforce performance optimization with a summary task.

Performance optimization summary

Boosting game performance begins by profiling to detect CPU and GPU bottlenecks. To lighten the CPU load, objects are merged with Static/Dynamic Batching and garbage collection (GC) stalls are prevented via Object Pooling. To ease GPU workload, LOD groups scale down detail over distance and hidden objects are culled with Occlusion Culling.

// Core optimization workflow:
// 1. Measure with Profiler (do not guess)
// 2. Relieve CPU via Batching and Pooling
// 3. Relieve GPU via LOD and Occlusion

When these techniques cooperate, even the most demanding scenes run smoothly at high frame rates.

Exercise Format performance summary

Using the values drawCalls (120) and pooledObjects (50), print "Optimizasyon: 120 Draw Call | 50 Havuz Nesnesi" to the console using Console.WriteLine.

Show example solution

using System;

class PerformanceSummary
{
    static void Main()
    {
        int drawCalls = 120;
        int pooledObjects = 50;
        Console.WriteLine($"Optimizasyon: {drawCalls} Draw Call | {pooledObjects} Havuz Nesnesi");
    }
}

Test yourself

Which of the following is directly used to prevent Garbage Collection (GC) stutters?
- Adding LOD Groups to mesh models
- Baking Occlusion Culling data
- Applying Object Pooling for frequently spawned objects
- Increasing texture sizes of all materials
Show answer

Applying Object Pooling for frequently spawned objects — Object Pooling keeps objects in a reusable pool instead of destroying and re-instantiating them, preventing memory allocations and GC spikes.

Assign isStatic flag

// Batching optimizasyonuna dahil etmek icin static yap
gameObject.____ = true;

Show answer

// Batching optimizasyonuna dahil etmek icin static yap
gameObject.isStatic = true;
