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 OcclusionWhen these techniques cooperate, even the most demanding scenes run smoothly at high frame rates.
Practice 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.
Starter code
using System;
class PerformanceSummary
{
static void Main()
{
int drawCalls = 120;
int pooledObjects = 50;
// Performans metriklerini formatlayarak yazdir
}
}Sample solution
using System;
class PerformanceSummary
{
static void Main()
{
int drawCalls = 120;
int pooledObjects = 50;
Console.WriteLine($"Optimizasyon: {drawCalls} Draw Call | {pooledObjects} Havuz Nesnesi");
}
}Expected output
Optimizasyon: 120 Draw Call | 50 Havuz Nesnesi
Questions and answers
Review the lesson questions together with their answers. To test yourself, solve the lesson interactively.
1 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 Correct answer
- Increasing texture sizes of all materials
Explanation: Object Pooling keeps objects in a reusable pool instead of destroying and re-instantiating them, preventing memory allocations and GC spikes.
2 Assign isStatic flag
// Batching optimizasyonuna dahil etmek icin static yap
gameObject.____ = true;// Batching optimizasyonuna dahil etmek icin static yap
gameObject.isStatic = true;Explanation: The gameObject.isStatic property marks the object as static, enabling optimizations like static batching.
