In recent times, the The fight to become the best PC-type portable console has begun, and at the center of this confrontation we find the Lenovo Legion Go S with SteamOS as a great protagonistUntil recently, Windows 11 was the most common option for devices of this style, but the emergence of Valve's operating system, optimized for gaming, has changed the situation and has opened up new possibilities for users seeking performance and flexibility in the portable game.
Steam OS, developed from Linux and adapted by Valve for its Steam Deck, has proven to be capable of get more out of the hardware compared to Windows 11, all with a more polished experience for gamers. Now that the system can be installed (or purchased pre-installed) on the Lenovo Legion Go S, we've been able to truly test whether the theory holds true outside of Valve's ecosystem. The results leave no doubt.

One of the main reasons to choose SteamOS in the Legion Go S is the pure gaming performance. Tests carried out with titles such as Returnal, Cyberpunk 2077 or Doom: The Dark Ages have put on the table strong differences.

At lower resolutions and low graphics settings, such as 1280x800 in "low" mode, the trend persists: SteamOS has the advantage in most cases, especially in games that are very demanding on the CPU or GPU.
The secret of this superiority lies in the fact that SteamOS is designed to focus all hardware resources on the game, eliminating background tasks and other unnecessary processes present in Windows. This optimization results in a smoother execution and a battery that, according to various analyses, can last even twice as long in less demanding titles compared to Microsoft's operating system.
Continuous improvements and user experience in SteamOS

These improvements aim to make SteamOS the de facto standard on handheld consoles, especially if Microsoft maintains its strategy with full versions of Windows.
