Why use it
Use CapFrameX to compare builds, scenes, and hardware through repeatable captures rather than feel, exposing spikes, low-percentile performance, and pacing problems hidden by average FPS.
Where it fits
Use testing, performance, accessibility, and diagnostic tools to remove problems players will notice.

What to check
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.
