Practical articles on CPU, GPU, memory and engineering process optimization.
Huge Worlds, Huge Performance: Huge worlds fail when you treat memory like it is infinite. If everything stays loaded, you hit a bottleneck wall in memory, loading, and frame stability long before your content roadmap is done.
Metrics only matter if they drive decisions. This module shows how to set red/orange/green budgets, measure main vs render thread correctly, and automate repeatable Unity performance tests with markers, medians, and GC data.
Discover the performance challenges of crowd rendering & how to render thousands of character in Unity within your tight performance budget
Events and delegates can look innocent and still feed the GC. This module shows the cached-delegate fix, the custom event-manager route, and the JSON overwrite/manual parsing moves that cut scripting allocs before they turn into hitching.
Dynamic resolution and upscaling are how you buy back GPU frame time without defaulting to a blurry disaster. This module shows the first support gates, the camera/pipeline setup, the Frame Debugger proof path, and the quality tradeoffs across TAAU, FSR, and DLSS.
Make your expensive scripts cost nothing while they are offscreen
MEM - Class vs Struct in Gamedev: stop repeating the stack-vs-heap myth and start profiling what actually hurts. This module shows when structs help, when copies bite back, and how a simple string path can jump from hidden GC debt to a measured fix.
A Consistent Profiling Scenario is how you stop optimizing profiler noise. This module shows how to build one deterministic worst-case test, compare builds with real charts, and control CPU-frequency drift so your performance decisions are actually trustworthy.
Loading time starts at app tap, not when your splash screen feels done. This module shows Rubens 10-second-profiler trick, the 11-second Android proof, and one practical win: moving long audio clips from Decompress On Load to Streaming to claw back about 1.5 seconds.
Discover the true cost you're paying for the sneaky "shader variants" that Unity creates by default and how to stop paying for it.
This module is part of the full Unity Performance Taskforce archive. Oculus Developer Hub gives you better visibility, `sealed` keeps inheritance under control, overdraw shows where the GPU is burning cycles, and incremental GC helps you avoid spikes when the frame budget is already tight. It is a
Learn how to protect your most sensitive code from the classic "sloppy programming" by using the KISS Transaction Pattern for Unity.
