FPS Checker

What is FPS Checker?

A lightweight browser tool that measures frame rates, verifies monitor refresh rates, and helps diagnose display issues without installing anything. It includes an FPS meter, stress test, CPS (clicks per second) test, dead-pixel checker, and a frame time calculator. Run quick checks to confirm your 60/144/240Hz settings, spot micro-stutter or dropped frames, and validate hardware acceleration in your browser. Results are instant and run locally — no personal data is collected. Friendly for gamers, hardware enthusiasts, and developers who want a fast way to verify display performance and troubleshoot problems.

Key features

• Measure real-time frames per second directly in your browser.
• Verify your monitor's refresh rate and detect mismatches quickly.
• Run stress tests to evaluate stability under heavy browser load.
• Check click speed with an integrated CPS test for training.
• Find stuck or dead pixels using full-screen solid color patterns.
• Convert FPS to milliseconds with a frame time calculator.
