Used Cars Simulator is officially rated as Playable on Steam Deck by Valve, falling just short of the Verified tier. While the game runs on SteamOS through Proton compatibility, players face noticeable hurdles, including small in-game UI text, partial controller support, and demanding performance requirements that can cause frame rate drops in active gameplay.

Official Steam Deck Compatibility Status

Valve's Steam Deck review system categorizes DreamWay Games' title as Playable rather than Verified. The game meets basic execution criteria on SteamOS, but it comes with several caveats noted on the official Steam store listing:

Compatibility FactorOfficial StatusDetails
Steam Deck RatingPlayableValve-reviewed; not yet Steam Deck Verified
ProtonDB RatingGoldCommunity-tested on Linux and SteamOS
Text LegibilityWarningSome in-game text is small; Steam Deck magnifier is recommended
Controller SupportPartialController input is functional, but manual navigation or touchscreen interaction may be needed
Display ResolutionDefault / ScaledRequires adjustment; external high-resolution output causes heavy strain

Developer responses on the official Steam community forums confirm that dedicated Steam Deck optimizations remain an ongoing target. As stated by the development team, further adjustments are planned to bring the title closer to full Verified status.

Performance and Hardware Demands

Used Cars Simulator features an open-world physics sandbox with vehicle driving, towing, scrap trading, and car restoration mechanics. Because the game renders dynamic vehicle parts, damage physics, and open terrain, it demands substantial GPU and CPU power.

Official PC minimum requirements specify an Intel Core i3-4130 or AMD FX-8350 paired with an Nvidia GeForce GTX 1050 Ti or AMD Radeon R9 280 and 8 GB of RAM. The recommended requirements jump significantly to an Intel Core i7-9700 or AMD Ryzen 5 3600 paired with an Nvidia RTX 3060 or Radeon RX 5700 and 16 GB of RAM.

On the Steam Deck's custom APU, performance can fluctuate significantly:

  1. Docked Mode Limitations: Community players reporting on Steam discussions have noted severe performance dips—often falling below 20 FPS—when attempting to run the game through a dock to an external 4K monitor. DreamWay Games developers advise manually reducing in-game render resolutions and graphics toggles rather than outputting native high-resolution displays.
  2. Menu vs. In-Game Discrepancies: Community reports logged on ProtonDB highlight instances where unconstrained frame rates in the main menu drop substantially once loading into the open world environment.

Community Proton Tweaks and Testing

Players running Used Cars Simulator on Linux distributions and Steam Deck have tested several Proton compatibility layers:

  • Valve Default (Proton 9.0-4 / Proton Experimental): Standard execution works out of the box, though players on Proton 9.0-4 have occasionally reported visual hitching after window switching or significant drops after loading saves.
  • Custom GE-Proton (GE-Proton10-34): Linux community reports indicate successful gameplay using custom GE-Proton releases via external launchers and desktop mode, retaining Gold-tier stability.
  • In-Game Text Management: Because some in-game text is small, players can use the magnifier to read it.

Controller Configuration

The Steam store lists Used Cars Simulator with partial controller support, including standard Xbox layout mapping and wired USB DualShock controller support.

Frequently Asked Questions

Is Used Cars Simulator Verified on the Steam Deck?

No. Used Cars Simulator currently holds an official Playable rating from Valve. It can be played on the device, but it is not Verified due to small font sizes and partial controller support.

Why is the frame rate low when connected to a TV or monitor?

The game is graphically demanding and requires lowering rendering settings. Outputting to high-resolution external screens (such as 1440p or 4K) overburdens the Steam Deck APU, resulting in sub-20 FPS performance. Keep the internal game resolution at or near 720p/800p.

How do I read small text in the car shop menus?

Hold the Steam button and press the Left Bumper (L1) to activate the SteamOS screen magnifier whenever reading small car statistics or shop menus.

Does Used Cars Simulator support Steam Cloud on the Steam Deck?

Yes. The official Steam store metadata confirms Steam Cloud support, allowing save files to synchronize between your PC and Steam Deck.
