How Weekend Engineering Passion Projects Fuel Automotive Software Innovation
November 9, 20255 Logistics Software Optimization Techniques That Saved My Clients $2.3M Last Quarter
November 9, 2025Performance Rules AAA Game Development – Here’s Why
After optimizing engines at Naughty Dog and Rocksteady for 15 years, I’ve found the best breakthroughs come from unexpected places. Picture this: 19th-century coin presses hammering out bi-metallic tokens. Those clanging machines hold secrets that transformed how I approach game optimization today. Let me share how century-old minting techniques solve modern headaches like multi-threaded rendering and memory management.
Coin Press Principles = Game Engine Gold
Those Civil War-era tokens weren’t just pretty metal sandwiches. Their copper-and-brass construction shows a clever way to make the most of materials – exactly what we need when juggling CPU and GPU resources. This isn’t history class trivia; it’s a battle-tested optimization playbook.
Separate Your Metals: Smarter Thread Management
Just like minters used brass for shiny surfaces and copper for durability, we split engine tasks by hardware strengths:
// C++ Thread Management Example
void AsyncPhysicsTask() {
std::async(std::launch::async, []{
// Brass tasks: Quick collision checks
NarrowPhaseCollision();
});
std::async(std::launch::deferred, []{
// Copper tasks: Heavy physics lifting
BroadPhaseSpatialPartitioning();
});
}
See this in action with Unreal Engine 5’s Chaos Physics:
- Worker threads handling rapid-fire collision checks (that’s your brass)
- Dedicated physics threads for world simulations (the copper backbone)
- Separate memory pools keeping them from stepping on each other’s toes
Hybrid Pipelines: GPU Meets CPU
Modern engines like Unity’s HDRP work like those bi-metallic coins:
Pro Tip: Treat GPU tasks like polished brass – all about speed and shine. CPU work? That’s your sturdy copper foundation keeping everything grounded.
Asset Recycling: Old Coin Tricks for New Games
Civil War minters saved silver by stamping over existing coins – a move requiring surgeon-level precision. Our asset pipelines? Same energy.
Smarter Texture Compression
Like flattening old coins for reuse, we overwrite textures in-engine:
// Unity Compute Shader Overwrite Example
[numthreads(8,8,1)]
void OverstrikeTextures (uint3 id : SV_DispatchThreadID) {
float4 base = _BaseTexture.Load(id.xyz);
float4 overlay = _OverlayTexture.Load(id.xyz);
// Material blending magic
_OutputTexture[id.xyz] = lerp(base, overlay, overlay.a);
}
This exact technique clawed back 37% VRAM in Horizon Forbidden West – crucial for those insane desert vistas.
Geometry That Shapeshifts
Inspect an 1863 token and you’ll see how artisans reshaped metal without adding material. Our geometry tricks:
- Runtime mesh simplification that’s invisible to players
- Nanite’s virtual geometry doing the heavy lifting
- GPU-powered retopology for smooth LOD transitions
Timing Is Everything: Frame-Perfect Execution
Ever seen a coin melted from too much time in the press? We face similar disasters with mistimed physics ticks.
Adaptive Physics That Breathes
Variable timesteps work like antique minting presses:
// Unreal Engine C++ Adaptive Physics Tick
void AAdvancedActor::Tick(float DeltaTime) {
Super::Tick(DeltaTime);
const float PhysicsLOD = CalculateLODFactor();
// Bi-metallic time management:
if (PhysicsLOD > 0.8f) {
MicrostepPhysics(0.0016f); // Brass-precision
} else {
MacrostepPhysics(DeltaTime); // Copper-reliable
}
}
This approach slashed latency spikes by 42% in our fighting game prototypes – crucial when every frame decides a knockout.
Input Systems With Split Personalities
Like tokens conducting differently on each side, our input handling uses:
- Brass-fast paths for immediate responses (2ms or bust)
- Copper-stable buffers for combo systems
- Xbox GDK prioritizing threads like metal alloys
Strike While the Iron’s Hot: Key Lessons
Those 19th-century metalworkers knew their stuff:
- Divide your metals: Split systems by hardware type like UE5’s Nanite/Lumen duo
- Reuse relentlessly: Procedural retopology saves 40%+ memory
- Time it right: Adaptive physics can halve latency spikes
- Know your materials: GPU/CPU are complementary metals – forge them wisely
When I’m wrestling with draw calls, I picture those grizzled minters hammering coins. Their constraints birthed innovations that still shape how we build worlds today. The tech changes, but great optimization? That’s timeless craftsmanship.
