Mouse Input Lag Explained
Your mouse is the first link in the latency chain. A few milliseconds here compound with everything else.

Wired vs Wireless: The 2024 Truth
Modern 2.4GHz Gaming Mice Are As Fast As Wired
Top wireless gaming mice (Logitech Lightspeed, Razer HyperSpeed, etc.) now achieve <1ms latency, matching or exceeding wired connections. The old "wireless = laggy" myth is dead.
Exception: Bluetooth is still slow. Always use the dedicated 2.4GHz dongle.
Is Your Mouse Double-Clicking?
Worn-out mechanical switches can register two clicks instead of one. This is a latency AND accuracy issue.
