How to Find Steam Deck Compatible Games Before Buying

Nothing kills the excitement of a new game like discovering it doesn't run on your Steam Deck. You bought it on sale, downloaded 40 GB over hotel Wi-Fi, launched it — and got a black screen or an unplayable 12 FPS slideshow. The compatibility information exists, but it's scattered across four or five different sites. Here's how to check everything in one place so you never waste money on a game that won't work.

The four layers of Steam Deck compatibility

Not all "compatible" games are equal. There are actually four separate signals you should check before buying, and each one tells you something different.

1. Valve's official Steam Deck status

Valve tests games and assigns one of four labels: Verified (works perfectly out of the box), Playable (works with minor tweaks), Unsupported (known issues), or Unknown (not yet tested). This is the most visible indicator, but it's also the most conservative — Valve marks games as Playable for things like requiring an on-screen keyboard, even if the game runs flawlessly otherwise.

Right now, DeckAlly tracks over 21,000 games, including thousands with Verified and Playable status. Some examples of Verified games currently on sale:

• Resident Evil 2 — $9.99 (75% off), Proton Platinum, 8.8 hours to beat
• Devil May Cry 5 — $7.49 (75% off), 11.2 hours to beat
• Super Meat Boy — $1.19 (92% off), Proton Platinum, 9.3 hours to beat
• Resident Evil — $4.99 (75% off), Proton Platinum

2. ProtonDB community ratings

ProtonDB is a community-driven database where real players report how well games run through Proton (Steam's Windows compatibility layer). Ratings go from Platinum (flawless) down through Gold, Silver, Bronze, to Borked. This is especially useful for games Valve hasn't tested yet — the community often has reports months before Valve assigns an official status.

For example, Stray is officially marked as "Playable" by Valve, but ProtonDB users rate it Platinum — meaning it works perfectly in practice. Celeste and Balatro both carry Platinum ProtonDB ratings alongside their Verified badges, confirming they're rock-solid picks.

3. Performance benchmarks

Knowing a game "works" isn't enough. You want to know if it runs at 30, 40, or 60 FPS — and at what settings. Sources like SteamDeckHQ test games on actual hardware and report recommended settings, frame rates, and battery life estimates.

Games like Hades and Dead Cells run at a locked 60 FPS on Steam Deck with room to spare. Heavier titles like Sekiro: Shadows Die Twice (30.1 hours to beat) are Verified but may need settings tweaks to hit a stable frame rate. Performance data helps you set expectations before you buy.

4. Completion time

This one's underrated for handheld gaming. If you're playing on a Steam Deck, you're probably playing in shorter sessions — commutes, flights, lunch breaks. A 100-hour open-world RPG might not be the best fit for that use case. HowLongToBeat data lets you pick games that match your available time:

• Stray — 5.1 hours (main story)
• Balatro — 7.5 hours
• Celeste — 8.3 hours
• Ghost Trick: Phantom Detective — 12.0 hours
• DAVE THE DIVER — 25.0 hours

The problem: this data lives in five different places

To fully check a game's handheld compatibility right now, you'd need to:

1. Open the Steam store page and check the Deck Verified badge
2. Go to ProtonDB and search for the game's community rating
3. Visit SteamDeckHQ or YouTube for benchmark videos
4. Check HowLongToBeat for completion times
5. Open CheapShark, IsThereAnyDeal, or individual store pages to find the best price

That's a lot of tabs. And if you're comparing three or four games, you're juggling 15–20 tabs just to make a buying decision.

How DeckAlly combines it all in one search

DeckAlly was built specifically to solve this problem. When you search for a game or browse the catalog, you see all four compatibility signals — Verified status, ProtonDB rating, performance data, and completion time — alongside live deal prices from Steam, Epic, GOG, Fanatical, GamesPlanet, IndieGala, and more.

Here's what that looks like in practice. Say you want a short, verified game on sale right now:

Every row links to a game detail page where you can see the full breakdown — including which store has the best price, what settings to use on your device, and how long the game takes to finish.

It's not just Steam Deck

DeckAlly also tracks compatibility for Windows handhelds. If you own an ROG Ally, ROG Ally X, Legion Go, Legion Go S, MSI Claw, or AYANEO 3, the same database covers your device. You can filter the entire catalog by your specific handheld and see only games that are known to work well on it.

The device comparison page lets you see game libraries, performance stats, and compatibility breakdowns side by side across all eight active handhelds in the database.

Quick checklist before you buy

Before spending money on any game for your handheld:

1. Check the Deck status — Verified or Playable is what you want. Unsupported means known issues.
2. Check ProtonDB — Community Gold or Platinum means real players confirmed it works. This is especially important for games Valve marked as Unknown.
3. Check performance — "Runs" and "runs well" are different. Look for actual FPS numbers and recommended settings.
4. Check completion time — Match the game length to your play style. A 5-hour game and a 50-hour game are very different commitments on a handheld.
5. Check the price across stores — Steam isn't always cheapest. GOG, Fanatical, and Epic often undercut on the same title.

Or do all five at once: search on DeckAlly and see everything in a single view.
