4K Linux gaming duel: SteamOS vs Windows 11 on a flagship AMD rig
YouTuber ETA Prime built an all-AMD PC (Ryzen 7 9800X3D, RX 7900 XTX, 32 GB DDR5) and dual-booted Windows 11 Pro and SteamOS 3.7.17 to run Cyberpunk 2077, Borderlands 4, Forza Horizon 5, Spider-Man 2, and Red Dead Redemption 2 at 4K Ultra. Results vary by title: Cyberpunk 2077 nearly identical (84 FPS Windows 11 vs 85 FPS SteamOS), Borderlands 4 favors Windows (74 vs 69), Forza Horizon 5 favors Windows (191 vs 157), Spider-Man 2 edges SteamOS (111 vs 103), and Red Dead Redemption 2 leads Windows (96 vs 88). The test highlights that Linux/SteamOS gaming is viable today but performance is game-dependent, with a dual-boot setup offering flexibility to choose the best-performing OS per title while preserving Windows ecosystem access.
