The Xbox Full Screen Experience (FSE) for the ASUS ROG Xbox Ally handhelds has evolved into a fully-fledged "Xbox Mode" available for all Windows 11 PCs after a brief period locked to Xbox Ally, and then
handhelds only. Per a release from Microsoft, Xbox Mode has begun rolling out to all Windows 11 PCs of all form factors, and all you need to do is make sure your Windows 11 PC is up to date. Microsoft advises specifically turning on the "Get the latest updates as soon as they are available" setting under Settings -> Windows Update to ensure it's applied as soon as your device is ready.
On the off-chance you don't already know what Xbox Mode (formerly Xbox FSE) is, it's a controller-centric interface for launching and playing games on Windows 11, a la Steam Big Picture. We previously
tested it with the ASUS ROG Xbox Ally X, where we noted that it could sometimes provide very slight performance improvements when you launch directly into it, which skips loading the usual Desktop Window Manager (DWM) and also saves about 2GB of RAM. For particularly VRAM-constrained titles, like
F1 24, it did see a more noticeable improvement to average and 1% low FPS, but averages largely remained within 1-2 FPS between Xbox Mode enabled and disabled.
For those of you who want to enable Xbox Mode once you have the requisite updates, the instructions are fortunately very simple. All you need to do is click Start, type Settings, select Gaming, and then toggle Xbox Mode.
Xbox Mode is enabled by default on Xbox Ally handhelds, but if you want to enable the setting on other handhelds, you'll need to follow the same instructions, though your screen will say "Choose home app" instead. You'll also have an option to "Enter Xbox mode on startup," which in our testing can sometimes boost 1% average and FPS lows but doesn't majorly impact overall FPS.
In any case, it's cool that Microsoft has finally
opened up Xbox Mode for the wider public outside of Xbox Ally owners to enjoy. It's especially beneficial for users of
Game Pass, who would otherwise encounter issues hoping to launch their games through Steam Big Picture. It also doubles as a nice peek at what we can expect the console-PC hybrid
Project Helix UI to look like.
