Browser testing toolkit

FPS, Display & Gaming Input Tools

Choose the browser signal or visual behavior you actually want to inspect. FPS Tester keeps frame performance, monitor diagnostics, and gaming input tools separate so a browser observation is not mistaken for a native hardware certification.

FPS & Frame Performance

Measure this page’s browser animation cadence, inspect slow-frame tails, and translate frame rate into a usable millisecond budget.

FPS TesterMeasure live browser FPS, lows, jitter, timing spikes, and consistency in one session.FPS CounterKeep a bounded live view of current, rolling, and session browser frame rate.FPS Stability TestAnalyze how tightly frame intervals cluster instead of judging only the average.1% Low FPS TestSummarize the slowest frame-time tail with documented minimum sample requirements.FPS Drop TestFind unusually long browser timing intervals against a robust session baseline.Frame Time TestInspect frame intervals, percentiles, worst frames, and a millisecond timeline.Frame Pacing TestCheck cadence spread, in-band delivery, and recurring interval alternation.FPS to MS CalculatorConvert frames per second and milliseconds per frame in either direction.

Display & Monitor

Check browser-visible refresh behavior, generated display patterns, screen geometry, motion clarity, gradients, and dark-field uniformity.

Refresh Rate TestEstimate the current browser animation cadence and its nearest common refresh rate.FPS ComparisonCompare equal-speed motion sampled at multiple target frame rates.Screen Tearing TestUse moving edges and scan guides to look for visible motion discontinuities.Motion Blur TestFollow a controlled pursuit target to compare perceived motion clarity.Screen Resolution TestRead exposed screen dimensions, viewport, DPR, orientation, and color depth.Monitor TestOpen locally generated gamma, contrast, sharpness, uniformity, grid, and color patterns.Screen Bleeding TestInspect dark fullscreen fields for edge glow and uneven illumination.Color Banding TestCompare grayscale and RGB gradients with smooth or deliberate stepped output.PPI CalculatorCalculate pixel density, pitch, physical dimensions, aspect ratio, and viewing PPD.

Gaming Input

Observe browser-delivered pointer timing, estimate movement density from a measured distance, and test a complete visual response task.

Mouse Polling Rate TestEstimate how frequently mouse movement events reach the browser page.Reaction Time TestMeasure five randomized screen-to-input responses with honest chain-wide limits.Mouse Latency TestSummarize browser event delivery delay, intervals, P95, and timing jitter.Mouse DPI AnalyzerEstimate mouse DPI across repeated measured-distance runs with raw-input fallback.

All core measurements stay in the current page. Review the measurement methodology for formulas and the measurement disclaimer for browser and hardware boundaries.
