Retrotrauma — PS1 / PSX-Style Visual Overhaul

RETROTRAUMA

Retrotrauma is a visual overhaul for Barotrauma that transforms the game into a harsher, more authentic late-90s / PS1-style experience.

It modifies the game's rendering directly rather than simply applying a post-processing filter. Textures, geometry, UI, color depth, and audio can all be altered to create a more unstable, pixelated, low-fidelity look and sound inspired by early 3D games.

FEATURES

• Separate world and UI texture downscaling
• Nearest / point texture filtering with no smoothing
• PS1-style vertex snapping
• Camera-based texture wobble / affine-style distortion
• Dithering
• Color depth reduction
• Pixel font replacement
• Configurable low-quality / bitcrushed game audio
• Separate music bitcrush settings
• Separate voice chat audio settings

PERFORMANCE

Retrotrauma is not designed as a performance mod, but the lower-resolution textures may still slightly improve performance on weaker systems.

The difference will depend on your hardware and settings, so don't expect a massive FPS boost. And if your FPS is still low... at least you can experience it authentically now.

CONFIGURATION

Retrotrauma creates an editable config.xml after the game is launched with the mod enabled.

The configuration file can be found at:

%LOCALAPPDATA%\Daedalic Entertainment GmbH\Barotrauma\Retrotrauma\config.xml[/code]

You can quickly open the folder by pressing [b]Win + R[/b] and entering:

[code]%LOCALAPPDATA%\Daedalic Entertainment GmbH\Barotrauma\Retrotrauma

Most effects can be enabled, disabled, or adjusted directly in config.xml.

The config includes comments explaining what every option does, its valid range, and how stronger or weaker values affect the result.

Game audio quality can be reduced using configurable bit depth and sample-rate reduction settings.

Music has separate bitcrush settings and can be configured independently from other game audio.

Voice chat also has separate settings and remains at its original quality by default.

COMPATIBILITY

Retrotrauma is designed to be compatible with other Barotrauma mods.

If you encounter compatibility issues, visual bugs, audio problems, or other errors while using Retrotrauma with another mod, please report them in the Discussions section.
