It's been a few years since smaller form factor keyboards have taken the market by storm, and it doesn't seem like the trend of going compact is changing any time soon. E-sports players in particular crave that extra bit of mouse space.
But having the right layout is just one piece of the puzzle. Enter HFX, or Hall Effect switches—the latest tech shaking up the competitive gaming scene, which use magnets to detect key presses. HFX allows users to fine-tune actuation points among other features, pushing keyboard response time to the next level.
Perhaps it's no coincidence that shortly after our partnership, Team Vitality went on to win the Valorant EMEA Kickoff and CS2 IEM Katowice 2025. Read on to see how our champions utilize ROG Falchion Ace HFX to fine tune their keyboards and gain an edge over their opponents.
Adjustable actuation points are a game changer because you can modify any key's travel distance to your liking, to as little as 0.1mm. This means that if you wanted, you would only have to press a key for as little as 0.1mm to register an input, making movement as responsive as possible, reducing latency like never before. But obviously, you don't want to accidentally trigger any keys, so players can customize the actuation point key-by-key.
