Frequently Asked Questions
Is the Steam Deck OLED or ROG Ally better for beginners?
For a true beginner who wants a simple, plug-and-play, console-like experience, the Steam Deck OLED is the better choice. Its SteamOS interface is streamlined for gaming and requires far less technical management than the full Windows 11 desktop on the ROG Ally.
Which handheld is definitively better for Xbox Game Pass?
The Asus ROG Ally is definitively better for Xbox Game Pass. It runs Windows 11, allowing you to install the Xbox app and play games natively, just like on a PC. The Steam Deck can only access Game Pass through cloud streaming, which requires a strong internet connection and offers a less consistent experience.
What is the real-world battery life of the ROG Ally on AAA games?
When playing demanding AAA games in its high-performance 'Turbo' mode, the ROG Ally's battery can last as little as 50-70 minutes. In lower-power modes (10-15W), you can extend this to around 1.5-2 hours, but with a noticeable drop in performance.
Can the Steam Deck play games that aren't on Steam?
Yes, but it often requires some technical work. Using tools like Lutris or Heroic Games Launcher, you can install games from other storefronts like the Epic Games Store or GOG. However, compatibility isn't guaranteed, and it requires a willingness to 'tinker' with settings, unlike the ROG Ally where they install natively.
