Overwatch 2's professional scene is split almost perfectly between two mice: the Razer Viper V3 Pro and Logitech G Pro X Superlight 2, each commanding 44% of the market. This near-perfect duopoly is unique across esports and reflects the OWL legacy where Razer and Logitech were the dominant sponsors throughout the league's history. The DeathAdder V3 Pro picks up the remaining 13%, showing that some tank and support players still prefer ergonomic comfort for extended matches. What makes Overwatch 2 particularly interesting from a peripheral standpoint is that every single tracked pro uses a wireless mouse — the only title with 100% wireless adoption. The game's fast movement and frequent 180-degree flicks make cable drag genuinely unacceptable at the pro level. The average 4,000Hz poll rate is also the highest of any game, showing OW2 pros are early adopters of cutting-edge wireless technology. There's a strong argument that Overwatch 2 is the most mechanically demanding game in terms of what it asks from a mouse: you need the tracking consistency for beam heroes like Zarya, the flick precision for hitscan DPS, and the rapid 360-degree awareness for dive tanks — all in a single match if you're flexing between roles.
