MicroProfile
An open cross-platform instrumented profiler offering live overlays, web UI, context switches, and GPU timing in little source.
Why use it
It establishes frame budgets and repeatable captures early in an engine without complex dependencies.
Where it fits
Use testing, performance, accessibility, and diagnostic tools to remove problems players will notice.
What to check
Analysis features are basic, excessive markers distort results, and GPU support needs per-platform configuration.
