What happens when you install SteamOS on the most powerful gaming tablet ever made? I took the incredible ASUS ROG Flow Z13 KJP (Kojima Productions) Edition and completely ditched Windows 11 for official SteamOS 3.9! Powered by the massive AMD Ryzen AI Max+ 395, the Radeon 8060S iGPU, and 128GB of unified memory, this might just be the ultimate high-end Steam Deck alternative.
In this video, we push this hardware to the limit to see if games actually run BETTER on Linux and SteamOS than they do on Windows. Plus, I cover everything you need to know about TDP tuning on this APU, real-world battery life, and customizing the interface with CSS Loader.
🎮 Games Tested in this Video:
• Doom: The Dark Ages
• Cyberpunk 2077
• Elden Ring
• God of War Ragnarok
• Arc Raiders
• Marvel Rivals
