Chapter 1
What we measure
FPS Test helps you measure frames per second, frame time, and stability in browser WebGL workloads. We focus on frame pacing, smoothness, and troubleshooting rather than hardware leaderboard rankings.
The interactive FPS test tool stays on the run page at /run/. Home, blog, and guides link to it; the calculator and live controls are not duplicated elsewhere.
Chapter 2
Limitations
Browser FPS tests validate WebGL throughput and frame stability on your system. They complement in-game FPS counters and native benchmarks but do not replace title-specific testing.
Compare results only at identical settings and durations. Use exported JSON from /run/ to track changes over time.
