Kailh GX Switches developed by Endgame Gear
Designed for lightning-fast precision at all polling rates, the mechanical Kailh GX switches guarantee you won't miss a crucial click. Their SPDT configuration ensures optimal electrical contact and unmatched reliability. Featuring both top and bottom contacts, Kailh GX Switches excel whether you prefer extra low click latency in GX Speed Mode or security in GX Safe Mode. What sets them apart is their crisp, defined click sensation, offering tactile feedback for enhanced gaming control. Precise actuation and a balanced design ensure flawless, spam-friendly rapid-fire actions.
Techpowerup tested the OP1 8k (identical hardware and performance to XM2 8k), resulting in a click latency of 0.1ms and further adds: "Do keep in mind, however, that this number only accounts for firmware-level latency, as by enabling GX Speed mode, physical latency can be lowered by another 1.4 ms, placing the OP1 8K far ahead of the competition. In fact, I'm positive that the OP1 8K delivers by far the lowest click latency of any mouse released at this point." (Source: Techpowerup)
