It uses requestAnimationFrame – the browser’s built‑in method for smooth animations. By measuring the time between frames, we calculate your current FPS. This shows how fast your browser can render, which is a good indicator of general performance. Keep the tab active and don’t minimise it for accurate readings.

Three common reasons:

• Windows setting: Right-click desktop → Display settings → Advanced display → choose 144Hz.
• Cable limitation: HDMI 1.4 may cap at 60Hz. Use DisplayPort or HDMI 2.0+.
• Browser hardware acceleration: Turn it on in Chrome/Firefox settings.

Average human reaction time is around 200–250 ms. If you score below 200 ms, that’s above average. Below 150 ms is considered excellent (often seen in trained gamers). Try the test when you are well rested for your true baseline.

Regular clicking: 6–8 CPS. Jitter clicking: 10–14 CPS. Butterfly clicking: 14–20 CPS. Drag clicking: 20–50+ CPS. Be careful – drag and jitter clicking can strain your hand over time. This tool is just for fun; real gaming skill is about aim and timing, not just CPS.

Open the Keyboard Tester and hold down several keys at once – e.g., W, A, S, D, Space, Shift. If all of them light up and stay lit, your keyboard supports at least 6‑key rollover. To test full NKRO, try adding more keys. If some don’t register, that combination is ghosted. Most gaming keyboards have NKRO.

Go fullscreen and cycle through black, white, red, green, and blue. A dead pixel will stay black on all colors. A stuck pixel will stay one color (red, green, or blue). A hot pixel stays white. If you see a tiny dot that doesn’t change, that’s a defect. Try cleaning your screen first – sometimes dust looks like a dead pixel!

It gives a directional estimate based on component tiers. It’s great for seeing obvious mismatches (e.g., a very old CPU with a new GPU). Real‑world bottlenecks depend on the game, settings, and resolution. Use it as a starting point for upgrades, then check game‑specific benchmarks.

Our GPU test uses WebGL to render complex 3D scenes (like spinning cubes, particle effects, and lighting) and measures how many frames per second your graphics card can produce. It’s a browser‑based benchmark – not as precise as dedicated software like 3DMark, but great for comparing relative GPU performance across different devices. Keep in mind that results can vary based on drivers and browser optimisations.

The CPU test runs heavy mathematical calculations (like finding prime numbers, sorting large arrays, and hashing) to stress your processor. It measures operations per second, giving you a rough idea of your CPU’s raw compute power. Useful for comparing laptops or checking if thermal throttling is affecting performance. The test runs entirely in JavaScript – results are indicative, not lab‑grade.

The famous UFO test (originally from Blur Busters) shows moving UFOs at different speeds and refresh rates. It helps you spot motion blur, ghosting, or overdrive artifacts on your monitor. Use it to check if your monitor’s response time settings (like “TraceFree” or “OD”) are dialled in correctly. A clean UFO with minimal trail means your display handles motion well.

Our ISP test measures your download speed, upload speed, and ping (latency). Unlike other tools that require large downloads, we use small data packets to estimate your connection quality. Low ping is crucial for online gaming; good download/upload helps with streaming and updates. The test runs for about 10 seconds and gives you a snapshot of your current connection. (Note: it’s not a replacement for dedicated speed testers like Speedtest.net, but it’s handy for a quick check.)

APM (Actions Per Minute) counts every mouse click and keyboard press you make during a set time (usually 1 minute). It’s a popular metric in real‑time strategy games like StarCraft or Age of Empires. High APM can indicate fast decision‑making and efficient macro/micro. Our test gives you a baseline – but remember, effective APM (useful actions) matters more than raw clicks.

Yes! We’re constantly working on new tests. Planned additions include: microphone latency test, webcam FPS test, disk speed test, and RAM latency checker. If you have an idea for a tool, feel free to contact us.

First, check your monitor’s refresh rate in Windows: Settings → System → Display → Advanced display → choose the correct Hz. Also enable hardware acceleration in your browser (Chrome: Settings → System → “Use hardware acceleration when available”). Finally, ensure you’re not running on battery saver mode, which can limit performance.

You need to click anywhere on the page first to give it focus. After that, press any key – it should light up. If still nothing, try a different browser. Also check if your keyboard is properly connected. Some gaming keyboards have a “lock” mode (like Fn + Windows key) that can block inputs.

Both can add latency. A gaming monitor with low input lag (1–5 ms) helps. A high‑polling‑rate mouse (500–1000 Hz) reduces click delay. Also, wireless mice can have tiny delays. Try the test on a different setup to compare. Remember, your own reaction time includes these factors – the test measures your total system latency.

Click the “FULLSCREEN TEST” button. Your entire screen will fill with color. Move close to the screen and look for any dots that don’t match. Press ESC to exit. This works best in a dark room.
