Complete guide for game performance optimization — step-by-step workflow, tools, checklist, and expert tips to get started.
Capture baseline FPS, frame time, and draw call counts using the engine profiler on target hardware.
Analyze draw call budget, texture memory usage, and frame time breakdown to rank optimization targets.
Reduce draw calls, compress textures, and eliminate GC spikes based on profiler findings.
Re-profile after changes, validate particle system memory, and compare before/after metrics.
Convert FPS readings to millisecond frame budget when identifying bottlenecks.
Compare current draw call count against platform target during profiling.
Calculate VRAM savings from texture compression during optimization pass.
Check particle system memory footprint during final benchmark verification.
Key benchmarks for game performance optimization.
| Issue | Tool | Target |
|---|---|---|
| Draw calls | Profiler | <100 mobile |
| Overdraw | Frame debugger | Minimize |
| GC spikes | Memory profiler | Zero per frame |
Never optimize without profiling — guessing at bottlenecks wastes days on the wrong systems.
60 FPS equals 16.67 ms total — split budget across render, logic, and physics before optimizing any one system.
Fix performance at 30 FPS during prototype — retrofitting optimization after content lock costs 10× more.
