# Clair Obscur: Expedition 33 — UltraWide

✅ **Native ultrawide — no fix needed.** The game added official ultrawide support
in **patch 1.2.3**, and renders correctly at **5120×1440 (32:9)** on Proton with no
mod at all. Verified 2026-07-22.

- **Engine:** Unreal Engine 5 (no DRM)
- **Steam AppID:** 1903340
- **Method:** `native` — kept in the collection as a documented "works out of the box" entry

## Just play it

Set **5120×1440** fullscreen in-game. No install, no launch option, nothing to do.

```bash
./install.sh Expedition33     # prints "supports ultrawide natively — no fix needed"
```

## History: why there is no fix here anymore

This entry previously vendored [ClairObscurFix](https://github.com/Lyall/ClairObscurFix)
by Lyall (MIT) — an excellent fix when it was written. Two things made it the wrong
choice for the current game:

1. **It's archived** (last release v0.0.10, May 2025) and no longer tracks the game's
   builds. Its pattern scans began failing, and it **crashed on save load**.
2. **Its config flags don't gate its hooks.** Even with only `Center HUD` enabled, the
   `.asi` still installed `Level Load`, `Widgets`, cutscene, and PostProcess hooks into
   now-shifted code. Disabling features never reduced the crash surface — the only
   reliable fix was to not load it.

Meanwhile the game shipped official ultrawide support, so the fix became **pure
liability**: risk with no remaining benefit. Removed entirely.

**Takeaway for the collection:** a vendored fix against a live game is a decaying
asset. When the game itself catches up, the right move is to drop the fix and mark
the game native — not to keep nursing a broken mod.

## If a future game patch regresses ultrawide

The game has **no DRM**, so if native support ever breaks, a small dedicated
HUD-centering patch (one hook, not a dozen) is a viable path — far cleaner than
reviving an archived general-purpose fix.
