Star Wars Zero Company on Steam Deck

For Star Wars Zero Company on Steam Deck, use Remote Play from a capable PC if you want to continue your campaign on the handheld. Steam still lists local Deck compatibility as Unsupported, checked October 26, 2026. If the game stopped launching after Patch 1.2, restart SteamOS first: Valve announced a Steam Machine startup-crash fix applied by restarting, but that announcement does not establish improved Deck frame rates.

Can you play locally, or should you stream?

The Steam store badge is the compatibility baseline. A successful community setup can help you decide what to test, but its usefulness depends on which game patch, SteamOS and Proton version it actually used.

Patch 1.2 startup crashes: what Valve fixed

On October 16, 2026, at 23:11 UTC, Valve developer Pierre-Loup Griffais announced a fix for Zero Company crashing on Steam Machine. He said it would apply automatically after a system restart. Depending on your timezone, reports of that notice are dated October 17.

For an installation that worked before the update and now closes during startup:

1. Let Steam finish the game update and install available stable SteamOS/client updates.
2. Restart the system fully, then try launching with Steam's default compatibility selection.
3. If you previously added custom launch commands or forced a Proton version, record them and test the default configuration once.
4. If it still fails, verify the game files and record the game build, SteamOS and Proton selection for the crash report.

The announcement names Steam Machine. Treat it as a relevant startup diagnostic for SteamOS, not evidence that every Deck issue shares that cause. If your game already launches but runs slowly, move to the performance comparison instead of repeatedly changing Proton.

A settings test you can actually compare

Use one save and repeat the same camera movement and combat actions. Record the Deck model, SteamOS, Proton selection, game version, resolution, preset, upscaler and frame limit. This is a test plan, not a measured 30-fps preset.

If a 30-fps cap mostly displays frames below 30, it has not achieved that target. Likewise, an empty base or menu is not a combat benchmark. Hardware and scene limits remain possible even when Proton launches the game correctly.

The earlier version of this page used launch-period reports around 20 fps. Keep those as historical context, not a Patch 1.2 measurement. We have not run a new Deck benchmark, so choose from the current badge and repeatable evidence for your own setup.

Controls and text checks before a longer campaign

Before spending a session troubleshooting graphics, test the interactions you will repeatedly need:

• Rotate the camera and cycle targets while several units overlap.
• Open an ability tooltip and read the full AP and Advantage costs.
• Inspect the end-turn prompt and The Den's Personnel and equipment screens.
• Check whether the on-screen keyboard, trackpads or magnifier are needed.

Prefer a setting where you can read ability conditions over one with a slightly higher frame counter. Keep standard power controls during the first comparison so you can identify the useful change.

Set up Remote Play from a stronger PC

Valve's Remote Play overview describes streaming a game running on one computer to another device. The host handles rendering; the Deck receives video and sends input.

1. On the host PC, launch Zero Company locally and confirm that the campaign runs well at your chosen settings.
2. Sign in to Steam on both devices with the same account and enable Remote Play in the host's Steam settings.
3. Keep the host online with Steam running. In the Deck library, select the host/streaming option beside the game's launch control.
4. Start the stream and test target selection, camera movement and a short combat sequence.
5. If the host looks smooth but the Deck stream stutters, compare a wired host connection and a lower streaming resolution before changing the game's graphics again.

Remote Play uses the campaign running on the host. Local play on the Deck is a separate launch, so finish cloud synchronization before switching to it. If you use the EA app or Epic version, confirm your streaming setup supports that launcher; the Steam steps above describe the Steam copy.
