Welcome to Elderfield Steam Deck Performance and Controller Fixes

FIRST CHECK

Treat Verified as compatibility, not a smoothness guarantee; identify stutter, startup failure, or controller input before changing settings.

Start with the symptom, not the Verified badge. A game can meet compatibility requirements and still stutter on one route, fail to launch under a specific Proton state, or read the wrong controller layout. Those failures need different actions.

Start with the symptom

1. 01What fails?Identify cadence, startup, controller input, or the load list.
2. 02StutterReset to the supported baseline and test a stable external cap.
3. 03Will not launchRemove overrides, verify files, restart, and compare Proton state.
4. 04Controller problemCheck Steam Input, active layout, and controller order.
5. 05Missing load listUse backup-first save recovery, not graphics tweaks.

Measured expectation—not a guarantee

Steam Deck HQ reports a 50 FPS/50 Hz profile, approximately 10–13 W in its test, and an estimated four hours of battery life. That is useful configuration evidence for the reviewed build and test path. It does not guarantee the same result in every area, after every runtime update, or on every Proton configuration.

Start from the current default compatibility path. Apply one change at a time and retest the same location. If an external 50 FPS cap improves pacing, keep the cap and avoid stacking unrelated tweaks that make the next failure impossible to diagnose.

If the game stutters

The developer's public response connects a principal Deck stutter problem to the game's JavaScript runtime behavior under Proton, including garbage-collection effects. That matters because lowering every visual setting may not remove a runtime pacing problem.

Use this order:

1. Update the game and SteamOS.
2. Remove custom launch options and return to the default Proton path.
3. Verify the installed files.
4. Test a stable frame cap in the same location.
5. Record whether the hitch is periodic, area-specific, or tied to opening a menu.
6. If it persists, attach that pattern and build information to the developer support discussion.

Do not replace the bundled NW.js runtime as an assumed fix. The public sources do not establish that as a supported, low-risk procedure.

If the game will not launch

The public Proton tracker records startup failures for some configurations. First remove overrides that make your install different from the supported baseline:

1. Clear custom launch commands.
2. Return from a manually forced experimental or old Proton build to the current default.
3. Verify game files.
4. Restart the Deck fully.
5. Test from Gaming Mode and note whether Desktop Mode behaves differently.

If the issue remains, compare your SteamOS, Proton, and game build with the public report. Do not delete the save folder; launch failure and save-index failure are different symptoms.

If controller input is wrong

The official store lists full controller support. On Deck or a Windows handheld, confirm the active Steam Input layout and controller order. Disconnect duplicate virtual or physical controllers, reselect the official/default layout, and relaunch after the order is correct. If keyboard prompts appear but input still works, record it separately from complete input loss.

When to stop troubleshooting

Stop and report rather than escalating changes when the clean default configuration still fails, file verification repeats without repair, or a proposed fix requires replacing shipped runtime files. Preserve the save folder backup before any deeper experiment.
