Practical articles on CPU, GPU, memory and engineering process optimization.
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.
Exploit the right Render Mode tech for your Unity project
Your 350-boid prototype can be 35ms and still 'look fine'. That's how games die. This module walks GameObjects -> ECS -> Jobs + Burst -> spatial partitioning, and teaches the one metric that matters for scaling: total CPU time.
Serialization looks easy. Then you ship an update, change a data structure, and corrupt thousands of saves. This module gives you benchmarks + decision rules (time, GC allocs, size, migrations) so you pick the right format before it bites you.
Texture arrays are the forgotten tool: one texture object with many slices, switched by an index. Set Texture Shape = 2D Array, verify slices in RenderDoc, and sanity-check sample cost with Mali Offline Compiler. Full module + video is members-only below.
Rendering taking 40-50% on the Main Thread while worker threads idle? Not cool. Prove your render mode in Profiler + Player log, then enable Graphics Jobs (Native/Split) only when your target actually supports it.
These are the tools that help us daily in our game performance consulting practice
A no-BS stack to speed up your developer loop: Perplexity, ripgrep, T4 templates, Restic snapshots, WhisperX transcripts, Windmill automation, and remote hierarchy debugging for fast A/B performance signal.
BatchRendererGroup (BRG) is the stop-hoping-Unity-batches-it API. If you have repeated, static-like props and your render thread is paying for draw calls, this module shows the pattern: push data once, then drive visibility without exploding batches.
GPU Resident Drawer (GPU-driven rendering) can cut CPU rendering cost fast if your content fits. Benchmark snapshot: camera rendering 5.86ms -> 4.54ms, SetPasses 50 -> 13, draw calls 339 -> 139. Full step-by-step module + video is members-only.
As many so called "game devs" say: does the SRP batcher truly suck?
Not handling shader prewarming? Then yo are not helping your players pay you money.
