CachyOS has achieved a new milestone, with its distro share on ProtonDB now exceeding the peak share Arch Linux ever held. This development was reported recently by Boiling Steam, noting that CachyOS first surpassed Arch Linux to claim the top spot among desktop distributions on ProtonDB in March 2026. Boiling Steam noted that while ProtonDB data "may not be completely representative of all Linux gamers," it is considered "a good predictor where the market is going to shift." The increased share indicates a growing adoption of CachyOS among users reporting game compatibility through ProtonDB.
