Online FPS Counter Tester for Gaming Performance

Verify your monitor's true refresh rate and diagnose visual micro-stutters instantly. Our web-based FPS counter pushes your browser's rendering engine to the limit to reveal your exact Frames Per Second and frame time stability.

You just spent a significant amount of money upgrading to a 144Hz or 240Hz gaming monitor, but how do you know it is actually working? Windows often defaults new monitors back to 60Hz, leaving gamers playing at a disadvantage without even realizing it. Our Free Online FPS Counter bypasses the guesswork. By utilizing the requestAnimationFrame API, it forces your web browser to draw frames as fast as your monitor will allow. Watch the live chart below to verify your peak refresh rate and detect the painful micro-stutters that ruin competitive gameplay.

How to Read Your Telemetry Dashboard

Our tool begins testing the moment the page loads. To get the most accurate reading, constantly move your mouse pointer in circles over the page. This forces your web browser to stay in a "High Performance" state rather than dropping into an idle, power-saving mode.

• Current FPS: This is the live, raw number of frames your graphics processor is drawing every single second. It will fluctuate rapidly.
• Average: The smoothed-out mean of your last 120 frames. This is your "true" baseline performance.
• Peak Refresh Rate (Max): This is the single highest number achieved. Because a browser tab is incredibly lightweight to render, this number will almost perfectly match your monitor's maximum hardware capability (e.g., 60, 144, 240).
• 1% Low (Min): This is the most critical metric. If your average is 144 FPS, but your Minimum suddenly drops to 45 FPS, you just experienced a "stutter" or "lag spike."

Why is my FPS stuck at exactly 60? (How to Fix)

If you recently bought a 144Hz, 165Hz, or 240Hz gaming monitor, but our tool says your Maximum FPS is 60, you are not getting the hardware you paid for. This is the most common issue in PC gaming.

Here is how to unlock your true refresh rate:

1. Windows Settings: By default, Windows caps all new monitors at 60Hz for compatibility. Right-click your desktop -> Display Settings -> Advanced Display. Look for the "Choose a refresh rate" dropdown and set it to your monitor's maximum capability.
2. The Cable Bottleneck: Older HDMI cables (like HDMI 1.4) do not have the bandwidth to carry a 144Hz signal at high resolutions. You must use a DisplayPort (DP) cable or an HDMI 2.1 cable to unlock high refresh rates.
3. Browser Hardware Acceleration: Web browsers cap framerates to save battery life. Go into your browser settings (e.g., Chrome Settings -> System) and ensure "Use graphics acceleration when available" is toggled ON.

The Hardware Link: FPS vs. Monitor Refresh Rate (Hz)

People often confuse FPS and Hz, but understanding the difference is key to smooth gaming.

FPS (Frames Per Second) is a measure of your computer's "Engine" (the CPU and Graphics Card). If you are playing a heavy, beautiful game like Cyberpunk 2077, your computer might only be powerful enough to draw 50 frames per second. If you are playing a lightweight game like Valorant, it might draw 300 frames per second.

Hz (Hertz) is the physical speed limit of your monitor's "Glass." A 60Hz monitor physically refreshes the image on the screen exactly 60 times a second.

The Golden Rule: You only get the benefit of high FPS if your monitor has the Hz to match it. If your PC generates 300 FPS in Valorant, but you are playing on a cheap 60Hz office monitor, you will only actually see 60 frames. The other 240 frames are completely wasted.

Diagnosing Micro-Stutters: The "1% Low" Rule

Gamers often complain: "My game says I have 120 FPS, but it feels choppy and terrible."

This is due to poor Frame Pacing. FPS is an average over one full second. If your computer renders 119 frames in the first half of a second, completely freezes for the second half, and then renders 1 frame, your counter will say "120 FPS"—but your screen literally froze for half a second.

This is why reviewers rely on the "1% Low" (or Minimum) metric shown on our dashboard. This metric tracks the slowest frames generated. If your Average FPS is high, but your Minimum FPS is very low, your hardware is bottlenecking. This is usually caused by running out of RAM, a slow hard drive struggling to load textures, or a weak CPU holding back a powerful Graphics Card.

Frequently Asked Questions (FAQ)

Why does the graph dip when I switch tabs?

Modern web browsers (like Chrome, Edge, and Safari) aggressively throttle background tabs to save RAM and battery life. When you click away from this page, the browser instantly drops the rendering limit to 1 FPS or stops it entirely. Our tool is programmed to reset the math when you return to prevent these background drops from ruining your average.

Does this test my ping or internet lag?

No. FPS is purely a measure of hardware rendering power (your graphics card and CPU). "Ping" or "Lag" is a measure of network latency (how long it takes data to travel from your computer to the game server and back). You can have 240 FPS but still rubber-band around the map if your Ping is high.

What is Screen Tearing?

Screen tearing happens when your Graphics Card (FPS) and your Monitor (Hz) fall out of sync. If your graphics card pushes a new frame while the monitor is only halfway done drawing the old frame, the screen will look sliced in half. Technologies like V-Sync, G-Sync, and FreeSync were invented specifically to force the graphics card and monitor to talk to each other and prevent tearing.
