REPONativeUltrawide

REPONativeUltrawide

Probably the best ultrawide mod for R.E.P.O.

Other ultrawide mods get the game world right - FovUpdate, for example, expands the camera correctly - but they just stretch the interface to fill your screen, so the UI ends up distorted. This mod fixes the part they skip.

It adapts the interface to your ultrawide monitor: HUD elements, menus and prompts are rebuilt so they sit at the real screen edges - not squished, not stretched, the way it would look if the game shipped with native ultrawide support. It handles the game's rendering on its own too, so it works standalone.

Features

• No stretching - the game and the UI are adapted, not distorted
• HUD elements moved out to the true screen edges (same margins as 16:9)
• Menus, pause, lobby and settings spread across the full width; popups stay centered
• Loading screens, startup splashes and tutorial bars fixed too
• The mouse cursor reaches the whole screen
• The "old TV" lens distortion and chromatic aberration are toned down so the edges stay readable
• Works with any aspect ratio wider than 16:9 - 21:9, 32:9, whatever you've got
• Fully standalone - no other mods required

Compatibility

Runs on its own. Compatible with FovUpdate and, as far as I can tell, any other mod.

Client-side only - just you need it installed.

Configuration

A few toggles in BepInEx/config/com.github.NEDOSTUPN0.REPONativeUltrawide.cfg:

• Enabled - master switch
• Lens Distortion Fix - tone down the edge distortion and chromatic aberration on ultrawide
• A debug UI-dump key (unbound by default)

Notes

On screens 16:9 or narrower the mod does nothing - it only kicks in when your display is wider than 16:9. Ultratall (taller than 16:9) is not supported.

Fully vibe-coded with Claude Code - but it seems to work great anyway.
