Hearth and Hamlet Steam Deck Support and Crash Fixes
Hearth and Hamlet on Steam Deck: UI can sit off-screen and crashes happen. Try the Vulkan launch option. The developer is patching small resolutions.
Last verified: August 30, 2026 — covering Hearth and Hamlet patches 1.0.04 through 1.0.06 (August 24–29, 2026).
Steam Deck is best-effort, not a polished deck-verified sit. Players report UI off the screen, missing controller maps, and random freezes. Phorust is working on a small-resolution patch. Proper Steam Input is some time away. On Linux and Deck, several people got past crashes by picking the Vulkan launch option.
Patch notes that matter for Deck / crashes
| Patch | Change | Deck / crash relevance |
|---|---|---|
| 1.0.04 | Removed defunct telemetry | Less background activity, fewer intermittent stalls. |
| 1.0.05 | First-wave VRAM optimisation across hundreds of assets | May reduce white squares / missing textures and VRAM-related crashes. |
| 1.0.06 | Dozens of audio assets changed to use less RAM; Steam requirements raised to 16 GB recommended | Helps memory pressure on Deck and 8 GB desktops. 8 GB still works, but multitasking is tight. |
| 1.0.07 | Memory-footprint patch — hundreds of changes cut VRAM usage by about 1.1 GB | The biggest memory win so far, and the one aimed squarely at lower-spec hardware and VRAM-related crashes. |
What works today
| Issue | Status | Source |
|---|---|---|
| Runs on some Decks | Developer said it works on theirs, not extensively tested | Phorust |
| UI off-screen / unclickable | Reported; small-resolution patch in progress | OP + dev |
| Crashes / freezes | One tester: 6 crashes in 30 minutes | Player |
| Vulkan launch option | Fixed Linux crash-after-load for multiple people; dev asked Deck users to try it | Bug Reports + Deck thread |
| Controller / Steam Input | Wanted; developer said it may be some time away | Phorust |
| Touch | Not confirmed as a full replacement for mouse | — |
Steam lists Windows and Linux. Deck is a Linux handheld, so Linux notes apply. Mac is not listed.
Pinned known issues also cover UI scaling too high, Linux visual glitches, windowed mode cutting UI, and the enemy tracker jumping after a resolution change (save-and-exit fix). Turn UI scaling down or enable Auto UI Scaling before you refund.
Launch checklist
- Add the Vulkan launch option if the game dies when the loading bar fills.
- Drop UI scaling until every book corner is clickable. See Research Pages.
- Stay in a resolution the UI was built around; then save-and-exit if the raid tracker teleports.
- Do not expect a finished gamepad map. Mouse (or trackpad) is the live control scheme. Hover-to-click is on the developer’s priority list for hand pain, not shipped.
If it still will not start, the Bug Reports thread already has “failed to register the windows class” and stuck loading bars on desktop Windows — those are not Deck-specific.
FPS is a separate 60 Hz lock. See Unlock FPS.
