TL;DR
Skeldrift’s June 8 compatibility briefing lists four of today’s five top Steam games as Platinum on ProtonDB, meaning community reports indicate they run on Steam Deck and Linux with little or no setup. Forza Horizon 6 is the exception at Gold, which still points to strong playability but may require tweaks.
Four of today’s five listed top Steam games are rated Platinum on ProtonDB for Steam Deck and Linux play, according to Skeldrift’s June 8 compatibility briefing, signaling broad community-reported support for portable PC players using Valve’s handheld.
The highest-rated entries in the June 8 briefing are Gamble With Your Friends, Paralives, Subnautica 2, and Escape the Backrooms, each listed as Platinum on ProtonDB. In ProtonDB’s tier system, Platinum generally means a game works well through Proton without special setup reported by the community.
Forza Horizon 6 is listed as Gold. That rating still indicates strong compatibility, but it usually means players may need settings changes, launch options, or other small fixes to get the best result on Steam Deck or Linux.
ProtonDB ratings are based on community reports rather than Valve’s official Steam Deck Verified label. That distinction matters: a ProtonDB tier reflects player-submitted Linux and Proton experience, while Valve’s system is a separate compatibility review shown on Steam.

- Gamble With Your Friends — Platinum

Why It Matters
The ratings matter because Steam Deck buyers often check compatibility before paying for large downloads, multiplayer games, early-access releases, or graphically demanding titles. A Platinum or Gold rating can reduce the risk that a game will fail to launch, perform poorly, or require time-consuming fixes.
The June 8 list also points to a wider practical shift for Deck users: several current popular games are being reported as playable through Proton at a high level. That helps Linux gaming users make faster buying and install decisions, though individual results can still vary by Proton version, graphics settings, storage type, and updates after launch.

Background
Proton is Valve’s compatibility layer that lets many Windows games run on SteamOS and other Linux systems. ProtonDB tracks player reports and groups games into tiers: Platinum for games reported to work with little or no setup, Gold for games that work well after tweaks, Silver for playable games with issues, Bronze for games that run but may have major problems, and Borked for games reported as unplayable.
In the June 8 briefing, no game in the five-title list is rated Silver, Bronze, or Borked. The standout result is the cluster of Platinum ratings across different genres, from life simulation and survival to co-op horror and party-style multiplayer.
“Four of the five listed top games are Platinum on ProtonDB, with Forza Horizon 6 rated Gold.”

What Remains Unclear
The ratings do not confirm identical performance for every Steam Deck owner. Frame rates, battery life, controller behavior, online features, and anti-cheat support may differ by game version, Proton version, and system settings. It is also not yet clear whether later patches to any of the listed games will improve or reduce compatibility.

What’s Next
Deck players should watch for fresh ProtonDB reports after game updates and compare those reports with Valve’s Steam Deck Verified status on each Steam store page. The next meaningful change will likely come from player reports after patches, Proton updates, or changes to online services.
