How to use this test
- • Start at HD 30 FPS, then try 60 FPS or Full HD if your camera supports it.
- • Close heavy apps (screen recorders, many browser tabs) while measuring.
- • If FPS is low here, meetings will usually be choppy too.
Fix guides: Camera not working in Zoom • Teams camera not working.

How this test works
We open your webcam using getUserMedia, then measure frames over time in your browser. If available, we also read dropped-frame stats from the browser’s playback quality API. Everything is local.
- • Measured FPS is calculated from real delivered frames in your tab.
- • Dropped frames can indicate CPU overload, USB issues, or driver problems.
Troubleshooting
- • Lower resolution to 720p and retest (1080p often causes stutter).
- • Close heavy apps/tabs (screen recorders, games, multiple video calls).
- • Switch USB ports and avoid unpowered hubs.
- • Improve lighting to prevent the camera from reducing FPS.
- • Update webcam drivers/firmware and restart the browser.
Quick steps
- • Select the camera, target resolution, and target FPS.
- • Click Start Test and wait 5–10 seconds for stable readings.
- • If FPS is low, switch to 720p and retest.
- • Use the regular Webcam Test to verify you selected the correct camera.
If FPS is low or unstable
- • Increase lighting (dim rooms force longer exposure and lower FPS).
- • Lower target FPS to 30 and resolution to 720p for meetings.
- • Plug directly into the computer instead of a hub/dock.
- • On laptops, switch to “Best performance” power mode while on AC power.
When to use this test
- • When your webcam looks choppy or stutters in meetings.
- • When verifying a new webcam claims 60 FPS.
- • After changing lighting, USB docks, or drivers.
Safety and privacy
- • Video is processed locally and never uploaded.
- • Stop the test to release the camera when finished.

FAQ
What FPS is good for video calls?
30 FPS is the most common target for meetings. 60 FPS can look smoother but requires more CPU and bandwidth. If you can hold a steady 24–30 FPS, your video should feel fine.
Why does my webcam look choppy in Zoom or Teams?
Common causes are high resolution settings, CPU overload, a busy USB controller/hub, camera drivers, or low light (some webcams lower FPS in the dark). Lower resolution to 720p and close heavy apps.
Why is my reported FPS different from measured FPS?
Browsers report the camera’s requested/negotiated settings, but actual delivery can drop due to lighting, CPU load, or driver behavior. Measured FPS reflects what frames your browser receives.
Do you record or upload my video?
No. Video stays in your browser and is not uploaded.
Can low light reduce FPS?
Yes. Many webcams lower FPS to boost exposure in dim rooms. Improve lighting or lower resolution to stabilize frame rate.
