In the build-up to the new ROG Xbox Ally and Ally X handhelds, which release tomorrow (October 16), Xbox unveiled a Steam Deck-style compatibility system. It claims that “thousands of games” have already been tested, and we’re starting to see the results appear on the Microsoft/Xbox Store.

Much like Valve does with its ‘Verified’ and ‘Playable’ rating system, Xbox opts for ‘Handheld optimized’ and ‘Mostly compatible’ tags. It seems as if a game doesn’t pass every single check for handheld optimization, it will receive the latter rating. Xbox makes it clear where handheld optimization can be improved.

Handheld Optimized and Mostly Compatible labels start rolling out

The handheld compatibility program is starting to become more visible on the storefront. Games marked with a green label are Handheld Optimized, while the blue label denotes Mostly Compatible titles. The checklist for compatibility goes further into detail regarding optimization and support in five different categories:

• Game functionality with default configuration
• Xbox or handheld-specific controller icons
• Legible text and UI elements in a handheld form factor
• Correct resolution support for handheld devices
• Controller-friendly text entry or on-screen keyboard

During the announcement back at Gamescom in August, Microsoft also revealed the new ‘Windows Performance Fit’ indicator that should make it clear what kind of framerate you’ll be getting in the game based on real-world data. This is yet to be made obvious, or the data is yet to be compiled. You’ll notice ‘Performance check not available yet’ listed on games across the store.

You’ll also find new ‘Handheld compatibility’ filters on the Microsoft store, though they don’t seem to be functioning at the time of writing. Regardless, there are four filters you’ll be able to use:

• Handheld Optimized
• Mostly Compatible
• Unsupported
• Not Tested

The one thing to consider, however, is that not all Windows handhelds are made equal. Unlike the Steam Deck, which has a compatibility rating system specific to that device and its hardware, Xbox needs to cater to a range of Windows handhelds, such as the ROG Ally, Legion Go, and MSI Claw series, all of which have multiple generations.

Right now, the handheld compatibility program seems to prioritize the new Xbox Ally models, but the Windows Performance Fit feature is definitely going to be a key factor here, as it will use real-world data to assess game performance “on your specific device,” says Microsoft.
