Practical articles on CPU, GPU, memory and engineering process optimization.
The Few Groups You'll Ever Need: Mipmap & Culling Groups: Texture shimmer and off-screen simulation waste are two classic performance leaks that quietly stack into stutter. If you ignore both, you pay twice: GPU memory pressure plus CPU work the player never sees.
APV in Your Game? (Adaptative Probe Volumes): Learn when Adaptive Probe Volumes beat fragile manual probe workflows, how to switch them on in Unity 6, and the first debugger checks to catch bad probe coverage before it turns into lighting debt.
Know if you’re CPU‑ or GPU‑bound, see pipeline state changes, and separate work from wait before you touch a single shader.
Judge ‘feel’ with data. Percentiles reveal stutter risk; overlays connect numbers to on‑screen actions.
Sampling is only half the story, Superluminal makes it navigable. Filter by your scripts, expand the hot path, and act fast.
When the Editor profiler isn’t enough, sampling profilers expose engine and script hot paths from your actual build.
Mesh LODs in Unity 6.2+: Reduce LOD work without hand-authoring every variant, start with automatic import-time simplification, and know when Mesh LOD is a better first pass than classic LOD Groups.
Review Your Auditor, Presets & Assets: Cross-platform performance pain usually starts with inconsistency, not one giant bug. One asset imported wrong, one shader variant too heavy, one quality profile forgotten, and you are back in firefighting mode.
Squeezing Ray-Tracing: Ray tracing can either elevate your game or trigger a performance disaster, depending on how disciplined your setup is. If you enable everything globally, your frame-time cliff arrives fast.
Throw WebGL, learn WebGPU: If your web build still rides legacy assumptions, you are heading into a compatibility and performance bottleneck at the same time. Browser players feel every hitch, and they bounce fast.
UI Toolkit - Faster Than You'd Imagine: Stop losing frame time to menus, inventories, and overdraw. Learn how UI Toolkit cuts draw calls, when vertex budgets and atlases matter, and how to prove the UI is actually cheap.
"VRS" - Variable Rate Shading: Learn when Variable Rate Shading can cut GPU cost without obvious quality loss, how to gate it safely in Unity 6.1+ and URP 17, and the first SRI plus debug checks to prove the gains before you commit to a full implementation.
