What is Controller Latency?
Input latency is the time delay between pressing a button and your game registering that input. Lower latency means faster, more responsive controls.
0-5ms: Excellent
Pro-level responsiveness. Ideal for competitive FPS and fighting games where every millisecond counts.
5-10ms: Good
Standard for wired controllers. Suitable for most gaming scenarios including action and racing games.
10ms+: High Latency
Common with Bluetooth connections. May cause noticeable input delay in fast-paced games.
Connection Type Matters
The way you connect your controller significantly impacts input latency. Use this tool to compare wired and wireless performance.
-
USB Wired Connection
Typically 1-4ms latency. Most consistent and reliable for competitive gaming.
-
2.4GHz Wireless Dongle
Usually 2-8ms latency. Near-wired performance with the convenience of wireless.
-
Bluetooth Connection
Typically 8-16ms+ latency. Convenient but not recommended for competitive play.
REAL-TIME MEASUREMENT
Frequently Asked Questions
Common questions about controller input lag testing
Q What does "input lag" actually measure?
This tool measures the time between your controller sending data packets to your computer. It reflects how quickly your PC receives input signals, not the total system latency (which also includes display lag).
Q Why does WebHID give more accurate results?
WebHID bypasses browser limitations (like Chrome's 200Hz cap) and reads directly from your controller's hardware. This provides true 1000Hz measurement capability for precision testing.
Q How can I reduce my controller's latency?
Use a wired USB connection instead of Bluetooth. Update your controller's firmware. Close background applications. Some controllers support high-polling-rate modes (1000Hz) via software.
Q What's the difference between polling rate and latency?
Polling rate (Hz) is how often your controller sends data. Latency (ms) is the time between packets. They're inversely related: 1000Hz = 1ms intervals, 125Hz = 8ms intervals.
Unlock True 1000Hz Testing
Standard browser APIs are limited to ~200Hz polling. Connect via WebHID to bypass these restrictions and measure your controller's true performance up to 1000Hz.
