60 FPS is the standard for smooth gameplay. 144 FPS is considered high-refresh for competitive gaming. 240 FPS and above is elite-level smoothness. Below 30 FPS is generally considered unplayable for fast-paced games.

What does this FPS test measure?

This test measures the actual frame rate delivered by your browser using requestAnimationFrame. It reflects your monitor’s refresh rate and your device’s rendering performance under browser conditions.

Why is my FPS capped at 60?

Most standard monitors run at 60 Hz, which caps browser rendering at 60 FPS. A 144 Hz or higher monitor with hardware acceleration enabled will show higher values.

How do I get higher FPS in my browser?

Enable hardware acceleration in your browser settings, close background tabs, update your graphics drivers, and use a high-refresh-rate monitor. Chrome and Edge typically perform best.

Frame time is the duration of a single frame in milliseconds. At 60 FPS the frame time is ~16.67ms. Lower frame time means smoother animation. Inconsistent frame times cause stutter even at high average FPS.

What is FPS?

FPS (Frames Per Second) measures how many unique frames your display renders each second. Higher FPS means smoother motion. This tool measures your browser’s actual frame delivery rate via requestAnimationFrame.

⏱

Frame Time

Frame time is the duration of a single rendered frame in milliseconds. At 60 FPS, frame time is ~16.67ms. Inconsistent frame times — even at high average FPS — cause visible stutter and reduce perceived smoothness.

🖶

Refresh Rate vs FPS

Your monitor’s refresh rate is the hardware ceiling for FPS. A 60 Hz monitor caps at 60 FPS regardless of GPU power. A 144 Hz or 240 Hz panel allows higher frame rates. Enable hardware acceleration to let your GPU drive browser rendering.

⚙️

Why FPS Varies

Background tabs, GPU load, browser throttling, V-Sync, and thermal throttling all affect browser FPS. Chrome and Edge with hardware acceleration enabled typically deliver the most consistent frame rates for web-based tests.

Frequently Asked Questions

It measures the frame delivery rate of your browser using requestAnimationFrame timestamps. Each callback records the time delta from the previous frame, which is inverted to calculate instantaneous FPS. The result reflects your display’s refresh rate under browser rendering conditions.

Most standard monitors run at 60 Hz, which caps browser rendering at 60 FPS. If you have a 144 Hz or 240 Hz monitor, ensure hardware acceleration is enabled in your browser settings and that your display driver is up to date. Some browsers also impose a 60 FPS cap in power-saving mode.

Enable hardware acceleration in your browser settings (Settings → System → Use hardware acceleration when available in Chrome). Close background tabs, update GPU drivers, disable browser extensions that intercept rendering, and use a wired connection if on a laptop running on battery. Chrome and Edge generally deliver the highest browser FPS.

60 FPS is the widely accepted standard for smooth gameplay. Competitive FPS players benefit from 144 FPS or higher, as the reduced frame time improves input responsiveness. 240 FPS+ is used by professional esports players. Below 30 FPS, motion becomes noticeably choppy in fast-paced games.

Yes. The 1% low (the slowest 1% of frames) often matters more than average FPS for perceived smoothness. A game averaging 144 FPS with a 1% low of 40 FPS will feel stuttery. The Min FPS shown in this test reflects your worst-case frame during the test window.

Metric	What it means
Avg FPS	Mean frame rate over the full test. The primary score.
1% Low	Average FPS of the slowest 1% of frames. More important than avg for perceived smoothness.
0.1% Low	Extreme worst-case frames — outlier spikes that cause jarring single-frame freezes.
Max FPS	Fastest single frame delivered. Indicates your display's peak headroom.
Jitter (±ms)	Standard deviation of frame times. Low jitter = consistent cadence = perceived smoothness.
Stutter %	Frames where delta > 1.5× median. Directly correlates with visible hitches.
Avg Frame Time	Mean ms per frame (1000 / avg FPS). Lower = smoother.
