Steam Deck and Windows handheld compatibility badges are not scores on one shared scale. Valve’s Steam Deck system uses four labels—Verified, Playable, Unsupported and Unknown—to describe a game’s expected usability on Deck. ASUS uses a separate, device-specific program for the ROG Xbox Ally family, including a “Should play great” Windows Performance Fit badge and a “mostly compatible” description. The labels have different owners, criteria and hardware scopes, so a Deck Verified mark cannot be treated as equivalent to an Ally badge or as a guarantee of the same frame rate.
The short answer: compare the program and the exact handheld first
When you see a compatibility label, ask three questions before drawing a conclusion:
As an Amazon Associate I earn from qualifying purchases.
- Who issued it? Valve issues Steam Deck and SteamOS ratings. ASUS describes the compatibility program for its ROG Xbox Ally and Ally X.
- What device does it cover? A rating is tied to the named hardware and program. It does not automatically apply to every Windows handheld or every SteamOS device.
- What is being promised? Valve’s labels summarize a usability review involving controls, display behavior and Proton support where relevant. ASUS’s “Should play great” badge is an expectation about how a game will play, look and feel on supported Ally hardware. Neither description creates a common performance scale.
The practical result is simple: check the game on the exact device you plan to use, read the reason behind the label, and treat measured performance as a separate question. A compatibility badge can tell you whether a game is likely to launch and be usable; it cannot, by itself, tell you that two different handhelds will deliver identical frame rates, battery life or image quality.

What the four Steam Deck labels mean
Valve displays a game’s rating in the Steam Deck library to set expectations about the amount of work a player may need to do. The labels are deliberately different rather than being four grades of speed.
#1 Best Overall
- International (UK) Version
- 7.4” diagonal, HDR OLED, 1280 x 800 x RGB, up to 90Hz Refresh rate, High performance touch, <0.1 ms Response time, 1,000 nits peak brightness (HDR), 600 nits (SDR)
- SteamOS 3.0 (Arch-based)
- 512GB NVMe SSD, 16GB LPDDR5 on-board RAM (5500 MT/s quad 32-bit channels), microSD UHS-I supports SD, SDXC and SDHC
- 6 nm AMD APU, CPU: Zen 2 4c/8t, 2.4-3.5GHz (up to 448 GFlops FP32
Verified: ready to use without special setup
Valve defines Verified as: “The game works great on Steam Deck, right out of the box.” That is a usability statement, not a promise that the title runs at a particular frame rate or resolution in every scene.
Valve’s review checks include whether the game accepts the Deck’s controls, displays suitable controller icons and brings up the on-screen keyboard when text input is required. The review also considers display behavior: support for the Deck’s default 1280×800 or 1280×720 resolutions, sensible default settings and text that remains legible on the handheld screen.
For Windows games running through Proton, Valve also considers whether the game and relevant middleware are supported by Proton. A Verified mark therefore reflects the configuration Valve reviewed at that time. Updates to the game, the Deck software or compatibility information can change the rating.
The Tool Desk
Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →Playable: usable, but expect a manual adjustment
Valve defines Playable as: “The game may require some manual tweaking by the user to play.” The adjustment can be minor. Valve’s examples include selecting a community controller configuration or using the touchscreen to navigate a launcher before the game starts.
Playable does not mean “broken,” and it does not identify one universal problem. The game may launch normally after one setting change, or it may require a recurring step whenever you start it. Open the game’s store page to see which Verified requirements it does not meet; that explanation is more useful than the color or label alone.
Unsupported: currently not functional on Deck
Valve defines Unsupported as: “The game is currently not functional on Steam Deck.” This is a negative compatibility finding for the Deck environment as reviewed, not a statement about the game on Windows hardware.
Common causes can include an essential launcher, anti-cheat component, control path or display behavior that fails in the Deck setup. The label can change if the game, Proton, SteamOS or Valve’s testing criteria change. If you experiment with another Steam Play compatibility tool, regard that as troubleshooting rather than a guarantee of a working result.
Quick wins for a faster PC:
Clear out junk files and repair common Windows errorsFree Scan →Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Repair Windows errors before they cause bigger problemsFix Now →Unknown: Valve has not checked it yet
Unknown means: “We haven’t checked this game for compatibility yet.” It is an absence of a Valve review, not a verdict that the title fails on Deck.
An Unknown game may work perfectly, may need configuration, or may fail for a reason no one has documented. Do not convert Unknown into Unsupported when making a purchase decision. Look for current community reports and, where possible, test within the store’s refund rules, but keep those reports separate from Valve’s official rating.
What Valve’s review covers—and what it does not
The Deck labels focus on whether a player can use the game successfully on a handheld with a specific control layout, screen and operating environment. The input review looks for full controller support, appropriate button prompts and an on-screen keyboard when needed. The display review considers the default Deck resolutions, readable text and usable default settings. Proton and related middleware matter when a Windows executable is being run on SteamOS.
Those checks answer a different question from a benchmark. They do not establish a cross-device frame-rate floor, a fixed battery-runtime target, identical visual quality or parity with a desktop PC. A Verified game can still have demanding scenes, optional graphics settings or performance that varies between areas. Conversely, a Playable game may run smoothly once its one manual hurdle is cleared.

Ratings can also move over time. A game update can introduce a launcher or anti-cheat change; a Proton update can fix or regress behavior; and Valve can update compatibility information. Treat the label as the current state of a program, not a permanent property of the game’s name.
SteamOS ratings beyond the Steam Deck
SteamOS is not one undifferentiated hardware category in Valve’s documentation. Valve’s Steamworks material distinguishes a rating for Steam Deck, a rating for Steam Machine and a rating for other compatible SteamOS devices.
This separation matters when a game is being evaluated on hardware that is not a Deck. A rating associated with one device category should not automatically be presented as a certification for another. The underlying SteamOS concept is similar: Windows executables without native Linux builds may run through Proton, a set of tools that runs the Windows executable and its game data on SteamOS. The hardware, firmware, display and control context can still differ.

Valve’s SteamOS Compatibility announcement described a system for devices other than Steam Deck and identified the Lenovo Legion Go S as the initial supported device in that announcement. That was an announcement-era statement, not a permanent or exhaustive list of every currently supported SteamOS handheld. For a purchase decision, check the current rating shown for the device category and the game rather than relying on the announcement alone.
How the Windows handheld example differs
ASUS describes its handheld compatibility program for the ROG Xbox Ally and ROG Xbox Ally X, which are Windows 11 handhelds. The program is tied to those named devices; it should not be generalized to every Windows handheld simply because they all use Windows.
“Mostly compatible”
ASUS uses “mostly compatible” to indicate that a game should work on the supported Ally hardware but may need minor adjustments. The phrase resembles Valve’s idea of a small manual step, yet the two programs do not publish a shared checklist that would make the labels equivalent. The same game can therefore carry different labels in the two ecosystems without either label being wrong.
“Should play great” and Windows Performance Fit
ASUS describes “Should play great” as a Windows Performance Fit badge. Its claim is that a game will play, look and feel great on the supported device. That is an expectation about the Ally experience, not a normalized score that can be lined up numerically with Verified.
The badge also does not state a universal frame-rate target. If you need a specific refresh rate, resolution, graphics preset or battery target, you need evidence measured on the exact Ally model and game version. The badge alone cannot supply those numbers.
Storefront access is a separate issue
ASUS says the Ally can access supported PC games from Xbox and other game stores. Its support information names Xbox Game Pass, Steam, Epic Games Launcher, Ubisoft Connect, the EA App and GOG Galaxy, and says storage can be expanded with a microSD card.
That list answers where a game may be obtained; it does not certify the game’s controls, launcher sequence, anti-cheat behavior, performance or device-specific fit. A title can be available through a launcher and still require touchscreen input, a compatibility setting or a separate sign-in step. Keep “the store is accessible” and “the game is compatible” as two different checks.

Side-by-side comparison of the programs
| Comparison point | Steam Deck and SteamOS | Windows handheld example | What you can safely conclude |
|---|---|---|---|
| Program owner | Valve defines the Steam Deck and SteamOS compatibility reviews. | ASUS describes the Ally compatibility program. | Always name the publisher and program when reporting a badge. |
| Primary scope | Deck, with separate categories for Steam Machine and other compatible SteamOS devices. | ROG Xbox Ally and Ally X in ASUS’s description. | Do not extend one device’s rating to an entire platform family. |
| Main labels described | Verified, Playable, Unsupported and Unknown. | “Mostly compatible” and “Should play great”/Windows Performance Fit. | The vocabulary is not interchangeable. |
| What the label summarizes | Usability checks including controls, display behavior and Proton support where relevant. | Expected ability to play, look and feel great on supported Ally hardware. | Both are compatibility guidance, but their published criteria differ. |
| Meaning of an unreviewed title | Unknown explicitly means Valve has not checked it. | No equivalent Ally Unknown status is established in the cited program description. | A missing Windows badge must not be treated as a failure. |
| Frame-rate guarantee | None in the cited rating criteria. | None stated as a normalized cross-device guarantee. | Use game-and-device performance measurements for frame-rate decisions. |
| Launcher and store access | Steam library presentation is central to the Deck labels. | Windows can access several launchers, including Steam and Xbox services. | Store access does not replace a compatibility check. |
How to check one game before buying or installing
Use the following process when comparing a Deck with a Windows handheld. It prevents a broad platform assumption from replacing a device-specific check.
- Identify the exact hardware. Write down “Steam Deck,” the relevant SteamOS device category, “ROG Xbox Ally” or “ROG Xbox Ally X.” Do not stop at “handheld PC.”
- Open the game’s store page on Steam. Locate the Deck compatibility label and read the explanation for any Playable or Unsupported result. Valve’s store-page details identify which requirements were not met.
- Classify the Deck result correctly. Treat Verified as ready-to-use guidance, Playable as a request for a manual step, Unsupported as currently nonfunctional on Deck and Unknown as not yet reviewed.
- Check the Windows program for the exact Ally model. If ASUS shows a badge for the game and model, record whether it is described as mostly compatible or Should play great. Do not transfer that result to another Windows handheld.
- Check the launcher path. Confirm where you will obtain the game and whether its launcher, sign-in flow and anti-cheat behavior are acceptable on the chosen operating system.
- Separate usability from performance. List your actual requirements—resolution, refresh rate, graphics preset, battery life or frame-rate target—and seek measurements for that exact game and device. Neither rating system supplies a common benchmark.
- Recheck after major updates. A game patch, Proton revision, SteamOS update or vendor firmware change can alter compatibility information.
What to do with a Playable or Unsupported Deck result
Start with the reason, not a generic tweak list
On the game’s store page, inspect the unmet Verified requirements. If the issue is a launcher, plan for touchscreen navigation. If the issue is controls, look for a suitable community layout or adjust the controller configuration. If text is difficult to read, review resolution and display settings rather than assuming that a faster processor will solve it.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsTry a different Steam Play compatibility tool only as an experiment
Steam Support describes forcing a Steam Play compatibility tool in the game’s Properties. The path is the game’s entry in your library, then its Properties, followed by the compatibility setting where you select a tool. This can help when a different Proton version addresses a known regression, but it is not a guarantee that an Unsupported title will work.
After changing the tool, launch the game and test the complete flow: sign-in, launcher navigation, controller input, a representative save and any online mode you need. If the change creates new problems, return to the previous tool or remove the override so Steam can use its default choice.
Do not confuse a workaround with a new rating
A community controller layout, touchscreen launcher step or forced compatibility tool may make a title usable for you. It does not change Valve’s published label immediately, and it does not establish that the same workaround will behave identically on another SteamOS device or Windows handheld.

“Verified is the same as Should play great”
No. Verified is Valve’s Deck-oriented usability result, with stated checks for input, display and Proton-related support. Should play great is ASUS’s Windows Performance Fit description for supported Ally hardware. The programs have different criteria and scopes.
“Unknown means the game is incompatible”
No. Unknown means Valve has not checked the game. It carries less information than either Verified or Unsupported and should prompt further checking, not an automatic rejection.
Best Value
- Valve is entering the gaming console marketplace with the new Steam Deck, a console geared towards PC gamers. The Steam Deck can be docked to a monitor, and used as a PC, or docked to a TV.
- Players can play a huge variety of games at any time with the comfort of a console and the freedom of a PC. Not anti-glare screen.
- Like the name suggests, the Steam Deck will include upgraded 1TB storage, and will include a carrying case. A micro SD slot will also enable expanded storage.
- Valve partnered with AMD to create a specialized APU optimized for handheld gaming, and Valve says the chip will deliver performance to run AAA gaming titles.
- The Steam Deck is outfitted with a 7-inch touchscreen, and two trackpads under the control sticks that allow gamers to operate games never designed outside of mouse and keyboard capabilities.
“Unsupported on Deck means it will fail on Windows”
No. Valve’s Unsupported label describes the Deck environment. A Windows handheld uses a different operating system and hardware configuration. You still need to check the specific Windows device, launcher and game requirements.
“Windows runs every PC game”
This overstates what a platform label proves. A Windows handheld may provide broad launcher access, but individual games can still have control, anti-cheat, launcher, display or performance issues. ASUS’s program makes claims about supported Ally models, not every Windows handheld.
Choosing a handheld when compatibility certainty matters
Choose the Deck workflow when you value a visible, four-state review
Steam Deck gives you a clearly named state and, for Playable or Unsupported titles, a way to inspect which requirements were not met. That is useful if you prefer to know whether a game has been reviewed for controls, display behavior and Proton support before installing it.
Crashes, No Sound, or Screen Glitches?

Repair common Windows errors and clear accumulated junk for a smoother, more stable PC - no reinstall needed.Free scan · no reinstallChoose the Ally workflow when launcher breadth is central
A Windows handheld can bring several PC storefronts and subscription services into one device environment. That may reduce the need to maintain separate operating systems for games tied to particular launchers. The trade-off is that the ASUS badge applies to the Ally family it names, and access to a storefront is not the same as a game-specific usability or performance guarantee.
For either choice, define your own acceptance test
- Does the game launch without a keyboard or mouse?
- Are all menus and launchers usable with the built-in controls or touchscreen?
- Is text readable at the device’s native display settings?
- Does online play work with the required anti-cheat system?
- Does performance meet your preferred frame-rate and battery targets?
- Will updates preserve the configuration you rely on?
The official badges answer only part of this checklist. Use them as a starting filter, then verify the requirements that matter to your own library.
Why no single compatibility score exists
Steam Deck and Windows handhelds combine several variables that a single number would hide: operating system, translation layer, driver version, control layout, screen resolution, launcher behavior, anti-cheat support and the power profile selected by the user. Valve’s label system emphasizes whether the experience is usable on Deck. ASUS’s Ally badge emphasizes expected play, look and feel on supported Ally hardware. Those are related goals, but they are not identical measurements.
That is why a responsible comparison names the program, device and game every time. “Verified on Deck” is precise. “Compatible with Windows handhelds” is not precise enough unless it identifies the model and the evidence behind the claim.
A practical decision rule
If the game is Deck Verified and carries an ASUS “Should play great” badge for the exact Ally model, you have positive signals from two different programs—but still not a promise of equal performance. If the Deck result is Playable, read the listed adjustment and decide whether that step is acceptable. If it is Unsupported, investigate the Windows device separately rather than treating the Deck result as universal. If it is Unknown, look for current device-specific evidence before buying.
In every case, keep three decisions separate: Can I obtain the game? Can I operate it on this handheld? Does it perform to my standard? The labels help most with the second question, provide partial context for the first, and do not replace measurements for the third.
