Quake Champions represents the oldest continuous lineage in competitive FPS — the game that literally invented esports deathmatch in the 1990s — and its mouse preferences reflect a community that values proven performance over cutting-edge trends. Zowie and Logitech dominate with 35% and 45% brand share respectively, but what's remarkable is how many classic shapes persist: the Zowie EC2-A, FK1, and FK2 are all heavily represented, and toxjq famously still competes with the discontinued Microsoft IntelliMouse 1.1. Only 35% of Quake pros use wireless mice, the lowest adoption rate of any game besides Dota 2, reflecting both the scene's veteran playerbase and the community's skepticism toward anything that hasn't been battle-tested over thousands of hours. The average eDPI of 1,466 sits between tactical shooters and hero shooters — higher than CS2's ~860 but lower than Overwatch 2's ~3,275 — perfectly matching a game that demands both precision Railgun flicks and rapid 360-degree Lightning Gun tracking. Mouse acceleration is a hotly debated topic unique to Quake, with several top players (k1llsen, cYpheR) using it to get low-sensitivity precision and high-sensitivity rotation speed from a single setup. The Quake pro scene may be small compared to Valorant or CS2, but it contains some of the most mechanically gifted FPS players who have ever lived — players who have been perfecting their aim for 15-20+ years.
