Sorry I forgot that. You can try this ? :

  1. Switch to Desktop Mode

    • Press the Steam button → Power → Switch to Desktop Mode.

    • From there, you can manage drivers and settings more easily.

  2. Force the Game to Use Proton Experimental

    • Go to your Steam Library.

    • Right-click on inZOI → Properties → Compatibility.

    • Check “Force the use of a specific Steam Play compatibility tool”.

    • Select Proton Experimental.

  3. Lower Graphics Settings

    • If the game launches, go to Settings and set everything to Low or Medium.

    • Disable V-Sync, Anti-Aliasing, and Post-Processing.

  4. Enable High Performance Mode

    • In Desktop Mode, open Steam Deck Performance Settings.

    • Set TDP limit and GPU clock to higher values (if safe).

    • Make sure Game Mode is optimized for performance.

  5. Update Steam Deck OS and Proton

    • Make sure your Steam Deck is running the latest system update.

    • Also update Proton via Steam settings.

  6. Try GeForce NOW (Cloud Gaming)

    • If local performance is too limited, you can play inZOI via GeForce NOW on Steam Deck using a browser.
