Why it’s here
Independent teams can compare builds, scenes, and hardware through repeatable captures rather than feel, exposing spikes, low-percentile performance, and pacing problems hidden by average FPS.
Best fit
Testing, performance, accessibility, and diagnostics expose friction before launch.

Before you commit
Capture targets Windows, and RTSS, HWiNFO, AIDA64, or other PresentMon tools may conflict; fix routes, warm-up, settings, and drivers for benchmarks and review bundled third-party licenses.
