Optimizing Performance in .NET Gaming
Overview
Performance is critical for immersive gaming experiences. This guide covers profiling, memory management, multithreading, and low‑level optimizations specific to .NET game development.
Key Topics
- Profiling & Benchmarking
- Garbage Collection Tuning
- Job System & Parallelism
- Entity Component System (ECS) Best Practices
- Native Interop & SIMD

GC Tuning
ECS Pattern
Job System
// Example: Configuring the GC for low‑latency gaming loops
GCSettings.LatencyMode = GCLatencyMode.LowLatency;
GC.TryStartNoGCRegion(100_000_000); // 100 MB
// Critical game loop...
GC.EndNoGCRegion();
// Simplified ECS iteration with struct components
public struct Position { public float X, Y; }
public struct Velocity { public float DX, DY; }
public static void UpdateEntity(ref Position p, in Velocity v, float dt)
{
p.X += v.DX * dt;
p.Y += v.DY * dt;
}
// Using System.Threading.Tasks for parallel physics
Parallel.For(0, entities.Count, i =>
{
var e = entities[i];
UpdateEntity(ref e.Position, e.Velocity, deltaTime);
});
