When it comes to performance on portable consoles, the debate between SteamOS and Windows 11 is heating up. Lenovo’s Legion Go S, now available with both operating systems, has sparked comparisons that reveal clear advantages for SteamOS, especially in gaming scenarios.
Performance benchmarks favor SteamOS
Tech reviewer Dave2D recently compared the Legion Go S running SteamOS and Windows 11. In tests with games like Cyberpunk 2077, Doom Eternal, and Helldivers 2, SteamOS consistently delivered higher frame rates. The largest gap was seen in Cyberpunk 2077, where the SteamOS version hit up to 13 more FPS than Windows. Even the lowest gain—5 FPS in Helldivers 2—still underlined SteamOS’s efficiency in gaming performance.
Better battery life and power management
SteamOS not only improves frame rates but also boosts battery life by more than three hours, running the same games. This is critical for portable gaming, where longer sessions without charging are essential. The Lenovo Legion Go S with SteamOS consumes far less power compared to the Windows model, which can peak at 40W while charging—more than double the Steam Deck’s 15W limit.
Windows still offers wider compatibility
Despite the performance edge, Windows 11 remains more versatile, allowing users to install games from platforms like Epic Games and GOG. In contrast, SteamOS restricts access to the Steam ecosystem. However, as compatibility improves, dual-boot options may eventually let gamers choose between power efficiency and broader access.
