Recent comprehensive testing involving the Lenovo Legion Go S has revealed some astonishing insights: SteamOS, Valve’s customized Linux-based operating system, is not just closing the performance gap with Windows in gaming—it is often outperforming it. Across multiple rigorous benchmarks conducted by reputable sources such as Ars Technica, YouTuber Dave2D, and PC Gamer’s Jacob Fox, SteamOS has consistently outpaced Windows on the same hardware, delivering smoother frame rates in games ranging from blockbuster AAA titles to beloved classics.
The significance here cannot be overstated. For years, Windows has been the uncontested platform for PC gaming, supported by a vast ecosystem of drivers, games, and developer tools. The Lenovo Legion Go S marks the first device to officially support both Windows and SteamOS with equally optimized drivers, effectively allowing a controlled, side-by-side comparison without hardware variability clouding the results. The verdict? SteamOS claimed 10 victories, no losses, and only 2 ties in 12 tested games—a stunning reversal of expectations.
Why SteamOS Excels Where Windows Stumbles
This performance discrepancy shines a spotlight on what many veteran PC users have long suspected: Windows’ bloat and architectural overhead may be handicapping gaming performance, particularly on handheld or portable devices. Dave2D’s popular video, provocatively titled “Windows Was The Problem All Along,” encapsulates this frustration, illustrating how SteamOS delivers cleaner, more efficient gaming experiences. The often-cited annoyances of Windows, such as unnecessary web integration in the start menu search or the rampant inclusion of AI-driven “features” that most gamers neither need nor want, contribute to an overwhelmingly “heavy” experience that SteamOS avoids by design.
Technically, Windows has a decades-old legacy of backward compatibility and feature creep. This legacy means more background processes and layers of software abstraction that, while sometimes invisible, consume precious system resources. SteamOS, built from a lean Linux kernel and stripped-down specifically for gaming, cuts through these inefficiencies, delivering raw performance more effectively. This is especially critical in handheld or portable PCs, where thermal and power constraints amplify the impact of software overhead.
Beyond Raw Performance: SteamOS’s Growing Ecosystem
Critics often point to SteamOS’s well-known Achilles’ heel: hardware and software compatibility. Historically, Linux-based systems have struggled with incomplete driver support and gaming compatibility issues—particularly for Windows-centric anti-cheat mechanisms and proprietary game engines. The practical outcome has been that while few could argue Linux’s performance potential, the reality was a patchwork of hit-or-miss game availability.
However, Valve has tackled these challenges head-on. The Legion Go S represents a milestone in hardware support, and Valve is actively expanding the SteamOS game compatibility list. Proton, Valve’s compatibility layer that facilitates running Windows games on Linux, has matured impressively. Titles once considered problematic now run fluidly on SteamOS. This progress is far from complete, but the trend is unmistakable: the SteamOS ecosystem is no longer a niche experiment but an emerging, viable contender.
Windows’s Uncertain Future in Gaming
Meanwhile, Windows faces growing criticism within the gaming community for its user experience fragmentation and systemic bloat. Microsoft’s attempts to integrate gaming more deeply—through the Xbox app ecosystem, app store infrastructure, and AI integration—have not universally improved player experience. Instead, these additions often feel like forced layers that may complicate rather than streamline gameplay on Windows devices, especially smaller, handheld PCs where every gigabyte of wasted memory or GPU cycles counts.
Microsoft promises improvements under the banner of an “Xbox Experience for Handhelds,” aiming to trim down and optimize Windows gaming environments. Yet history and user skepticism temper enthusiasm until proven results arrive. After decades, Windows’s legacy is hard to undo, and its inherent complexity may limit the efficiency gains possible without drastic systemic changes—changes unlikely to be universally popular or easily executed.
What This Means for the Future of PC Gaming
The performance results and user experience factors collectively suggest a tectonic shift in how PC gaming could evolve over the next few years. For enthusiasts currently locked into the Windows gaming ecosystem, SteamOS presents a serious alternative—one that could drive innovation by forcing Microsoft to rethink many entrenched design decisions.
Looking ahead, if Valve expands SteamOS support beyond handheld-specific hardware like the Steam Deck and Lenovo Legion Go S, and simultaneously improves game compatibility further, we could see a new mainstream gaming OS genuinely challenging Windows’s hegemony. This would introduce healthy competition, potentially liberating gamers from the frustrations of Windows’s bloat and dragging software layers.
From a consumer perspective, this also reinvigorates the dream of customizing and optimizing gaming PCs around a clean, purpose-built operating system that prioritizes performance and stability over unnecessary features. As someone who has grown increasingly exasperated with Windows’s quirks and bloat, I see Valve’s persistent efforts to refine SteamOS as not just promising, but necessary for a vibrant gaming future.
The landscape of PC gaming operating systems—once a given—is suddenly fertile ground for disruption. Valve has done more than just create a niche Linux spin-off for handhelds; it may have laid the foundation for a new era in gaming where performance and user experience take precedence over legacy baggage.
