I know of at least two extremely well documented reviews that demonstrated Fedora Workstation outperforming CachyOS. It's quite possible that the outcome would have even more strongly favored Linux if Fedora Workstation had represented Linux.
For example, see ukGages' YouTube video, "Linux Gaming Showdown: CachyOS vs Fedora" dated Feb 25, 2026.
Resident Evil Requiem has already set new Steam records and now turns attention to its performance on Linux. A recent benchmark comparison between Windows 11 and Linux CachyOS takes a closer look at how the game performs across multiple settings.
