Microsoft's recent advertisement for PC gaming featured Google Chrome pinned to the taskbar of a Windows computer, despite the company's promotion of its own browser, Microsoft Edge. The ad displayed Chrome prominently early in the video, which is notable given that nearly 95% of Steam gamers use Windows, with 70.83% having upgraded to Windows 11. Although Windows dominates the gaming sector, there is a growing interest in alternatives like Linux, which now supports about 90% of Windows games, though major titles remain unavailable due to anti-cheat systems. The inclusion of Chrome in the ad is seen as an anomaly, as promotional content typically avoids showcasing competitors. It is also noted that not all Microsoft employees exclusively use Microsoft Edge, suggesting a disconnect between the company's advertising and user behavior.

Riot Games has identified a significant security vulnerability in recent motherboards that could be exploited by cheaters, allowing cheats to operate undetected and undermining competitive gaming integrity. Major motherboard manufacturers, including Asrock, Asus, Gigabyte, and MSI, have released BIOS updates to mitigate this issue. If unaddressed, the vulnerability would have rendered existing direct memory access (DMA) detection and prevention technologies ineffective. The vulnerability involves DMA hardware devices connecting via PCIe slots, which could bypass input-output memory management unit (IOMMU) protections. Riot's Vanguard anti-cheat software may soon require players to update their BIOS to continue playing Valorant, and other anti-cheat systems are likely to implement similar checks.

Windows has been a key platform for PC gaming, evolving significantly by 2025 with advancements in handheld gaming and performance. The ROG Xbox Ally and ROG Xbox Ally X, powered by AMD Ryzen Z2 Series processors, were introduced, enhancing handheld gaming experiences. The Xbox Full Screen Experience (FSE) was launched for these devices, optimizing gaming interfaces. Advanced Shader Delivery (ASD) was implemented, reducing load times by over 80% for some titles. System-level performance improvements included tuned power management and lower CPU overhead. Windows also focused on Arm devices, enabling local game installations through the Xbox PC app and expanding compatibility with the Prism emulator. Native anti-cheat support was introduced for Arm devices, enhancing competitive gaming. DirectX 12 advancements included features that improved ray tracing performance by up to 2.3×. Bluetooth LE Audio support was added to enhance audio quality for gamers. Upcoming innovations include expanding FSE to more Windows devices, further ASD support, and a preview of Auto Super Resolution for improved visuals in games.

SteamOS is a Linux-based operating system developed by Valve, designed for the Steam Deck and other compatible devices, offering features like cloud saves and cross-device connectivity. However, it faces challenges with compatibility for games that use kernel-level anti-cheat systems and require Trusted Platform Module 2.0 support. Notably, games like Rust and Apex Legends have dropped support for SteamOS and Linux due to concerns over cheating and low user bases. Valve is working on anti-cheat solutions for SteamOS, but the lack of support from developers remains a significant barrier. Valve's hardware roadmap includes the Steam Machine and Steam Deck, but the Steam Machine will not receive financial subsidies like the Steam Deck. The success of SteamOS may depend on its ability to attract a substantial user base and persuade developers to collaborate on integrating anti-cheat systems.

Linux has reached 3.05% of all Steam users, up from approximately 2% last year. Windows' share has declined from around 95% to 94.84%, while macOS holds 2.11%. SteamOS accounts for about 27% of all Linux installations on Steam, aided by the popularity of the Steam Deck. Although SteamOS faces limitations with competitive multiplayer games due to a lack of support for kernel-level anti-cheat systems, nearly 90% of Steam's game library is accessible on Linux through Proton. Despite Linux's gains, Windows remains the dominant platform with nearly 95% market share.

Recent data indicates that nearly 90% of Windows games can now launch on Linux, particularly through SteamOS, marking a significant advancement in Linux gaming compatibility. However, games with kernel-level anti-cheat systems, such as the Call of Duty series and EA's Battlefield 6, remain incompatible with Linux. Some titles, like Helldivers 2 and Splitgate 2, have successfully integrated anti-cheat systems that work on Linux. The reliance on kernel-level anti-cheat has raised concerns about security vulnerabilities and gaming performance, as it restricts legitimate gamers while failing to effectively combat cheating.
