Practical articles on CPU, GPU, memory and engineering process optimization.
"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.
Fast&Sexy Audio Import Settings: Audio settings can quietly become a frame-time cliff: random spikes, memory bloat, and loading hitches that look like gameplay bugs. If you leave importer defaults untouched, you are likely burning cycles where players feel it most.
Building Your Own Performance Lab: Stop shipping blind. Build a multi-device Unity testing lab with heterogeneous hardware, remote access, and automated build distribution so regressions show up before launch.
Coding Like a `LLM Ninja`: Learn when to use one-shot prompts, IDE plugins, model/provider control, and plan-then-code workflows to ship Unity work faster without buying the hype.
Ever wondered why your Unity game lags? Discover the secret tools that tame performance woes!
The Six Exotic "Profiling Toys": You are probably losing time in a performance firefighting loop: the game stutters, you patch one script, and the hitch comes back somewhere else.
Frame Debugger is how you stop guessing why Rendering is slow: inspect the exact draw event (GPU state, batching breaks, bound textures) and map the frame with Render Graph Viewer. Complete members-only module + video below.
Stop guessing when you hit a bottleneck. This module shows how to use an LLM/VLM to analyze a Unity Profiler capture, starting with the exact questions to ask and a system-message template pinned to your target hardware + FPS.
Choosing the wrong serialization & deserialization technology inexperienced devs tell you about will only bring you pain
Motion vectors are the difference between cheap upscaling and ghosting soup. Learn what they are, how Unity generates them, how to debug them (Frame Debugger, RenderDoc, Rendering Debugger), and how Camera Motion Only vs Per Object affects both quality and cost. Full members-only module below.
Application SpaceWarp can double your Quest frame budget (pay 60, display 120), but it will punish motion-vector gaps and transparency fast. This module shows the setup, how to prove it is working, and the failure cases before you bet your build.
XR composition layers are the VR comfort cheat: keep UI/video crisp while the scene is loading or downscaled. The members-only module shows overlays vs underlays, depth submission tradeoffs, and the Quest profiling steps you need before you ship this into a headset.
