Frequently Asked Questions

What is input lag?
Input lag is the delay between a physical action (like clicking a mouse) and the visual result on your screen. It can stem from hardware, monitors, browsers, or OS scheduling.
Which platform has the lowest input lag?
Generally, a well-optimized PC with a high-refresh-rate monitor (240Hz+) and a gaming-grade mouse provides the lowest possible input lag, often under 20ms of total hardware delay.
Do wireless mice have more lag than wired?
Modern 2.4GHz wireless gaming mice from reputable brands now achieve latency parity with wired connections. However, Bluetooth is still unsuitable for low-latency gaming.
Does monitor refresh rate (Hz) affect input lag?
Yes, significantly. A 144Hz monitor refreshes its screen every 6.9ms, while a 60Hz monitor takes 16.7ms. Higher Hz directly reduces the age of the frame being displayed.
How can I reduce system jitter?
Enabling Windows Game Mode, updating GPU drivers, and closing background CPU-heavy tasks like Chrome or recording software can significantly stabilize your system's frame timing.
