Quick Answer
FPS monitoring tracks frame rate and frame time in real time during use; tracking compares sessions over time to spot regressions after updates or hardware changes.
Formula
Regression Detected when Median FPS drops > X% at identical settings
Introduction
This guide is part of the FPS Test knowledge base. Use the FPS test tool on the run page for live browser measurement, then work through the sections below to interpret frame delivery quality beyond a single average number.
You cannot fix what you do not log. This guide covers counters, overlays, exportable reports, and simple spreadsheets for historical comparison without drowning in data.
Monitoring Tools
Real-time FPS counters appear in game engines, GPU vendor overlays, and third-party tools. Prefer those showing frame time graphs.
Overlay software (Afterburner, vendor panels) adds GPU temperature and clock data alongside FPS.
Benchmark reports from built-in tests or browser JSON export create snapshots for tracking.
Historical performance tracking stores date, driver version, settings hash, and key metrics per session.
Session comparisons highlight regressions after Windows updates or driver releases.
Your first repeatable snapshot can come from the browser FPS test tool on /run/: export JSON after a fixed complexity and duration, then treat that file as row zero in your log.

- Overlay software with GPU telemetry
- Benchmark reports and JSON exports
- Historical logs with driver and settings notes
- Session-to-session comparison workflows
Tracking Discipline
Change one variable between sessions. Store results in a simple table: date, game, settings, avg FPS, 1% low, stability score.
When a regression appears, fix it systematically rather than random tweaks. The ordered workflow in FPS optimization techniques pairs well with tracking data because each change maps to a logged session.
Percent change formulas are noisy at high FPS. A drop from 300 to 270 FPS is 10% but may be irrelevant; a drop from 60 to 54 FPS can feel awful on a 60 Hz display.
ΔFPS = (New − Old) ÷ Old × 100%
- Export JSON from /run/ after each browser baseline
- Name files with driver version and date
- Re-test 48 hours after major updates
- Keep baseline scenes unchanged
Tracking Setup
Minimal viable logging beats perfect telemetry you never maintain. Start with three titles and one browser baseline.
-
Pick primary titles
Two or three games plus browser baseline. Add titles only after the habit sticks.
-
Standardize scenes
Same benchmark route every time. Write down patch version when games update.
-
Log metadata
Driver, OS build, power plan, room temp if possible. Metadata explains mysterious regressions months later.
-
Store exports
JSON from browser tool; screenshots from in-game overlays. Folder per machine if you own more than one PC.
-
Review quarterly
Spot slow regressions from background app creep. Quarterly review catches drift weekly glances miss.
-
Flag thresholds
Decide in advance what percent drop triggers investigation. Ad hoc panic wastes time on normal variance.
Tracking Examples
Spreadsheet with monthly browser stability score trending down triggers driver rollback test.
Overlay log shows GPU hotspot rising with same FPS, predicting future throttle.
Post Windows Update Tuesday: browser baseline unchanged, in-game 1% low down 12%; game patch next day restores prior numbers.
New GPU install folder: before and after JSON exports plus photos of settings menus for exact reproduction.
- Before/after GPU upgrade comparison folder
- Seasonal thermal comparison same benchmark
- Windows update Tuesday regression check
FAQ
- Do I need paid software to track FPS?
- No. Browser JSON export, in-game benchmarks, and free overlays are enough for most users.
- How often should I baseline?
- After driver updates, major game patches, or hardware changes. Monthly optional for enthusiasts.
- What should the browser tool log include?
- Average, min, max FPS, stability score, duration, and settings used during the session.
- Spreadsheet or dedicated app?
- Spreadsheets win for simplicity. Move to dedicated tools only if you automate capture or run many machines.
Conclusion
Monitor frame time in real time and track sessions over time. Consistent logging turns FPS from a guess into a trend you can optimize.
