Boiling Steam has published its latest December ProtonDB data, indicating a significant shift in Linux distribution preferences among gamers. The report highlights that CachyOS has surpassed Arch Linux in user share within the ProtonDB dataset, suggesting a growing adoption of the performance-focused distribution. This change follows a previous observed decline in Manjaro's usage according to the same metrics. Boiling Steam emphasizes that while the data may not represent all Linux users or even all Linux gamers, it serves as "a good predictor where the market is going to shift." The trend suggests evolving preferences for Linux gaming platforms, with CachyOS gaining momentum over traditionally popular distributions like Arch Linux for Steam-powered devices.
