Settings

Press F1 to open ReCarbon’s Settings at any time: in the game, in menus, during a race. On a Mac keyboard F1 is the brightness key, so press Fn+F1, or Cmd+,. On a controller, press View + Menu (Back + Start) together.

• Tabs: Q / E or LB / RB.
• Rows: the arrows, the D-pad or the left stick choose a row and change its value.
• Close: Escape or B.

Changes apply at once unless marked restart. They are saved to settings.toml in ~/Library/Application Support/ReCarbon/. An environment variable (for example RECARBON_AA=0) wins over the file for that run, and the menu shows it.

Generated

This page is generated from the option table in ReCarbon’s runtime/user/settings.cpp, as the macOS build shows it. Options hidden on macOS are left out.

Display

Fullscreen

Fill the screen with a borderless window. Off: a resizable window.

Default Off · On, Off

[video] fullscreen = falseRECARBON_FULLSCREEN

V-Sync

Show each frame on a display refresh. Off can tear, but frames appear sooner.

Default On · On, Off

[video] vsync = trueRECARBON_VSYNC

Frame Rate

Auto: 60, or 30 while the device is hot or can't hold 60. A steady 30 feels smoother than a shaky 60 (the Steam Frame's headset). The game keeps its speed.

Default 60 fps · Auto, 60 fps, 30 fps

[video] frame_rate = "60"RECARBON_FRAME_RATE

Aspect Ratio

Fill other screen shapes: a wider view on an ultrawide, a taller one on a Steam Deck or a 4:3 iPad, the HUD at 16:9. Or 16:9 with bars.

Default Fill Screen · Fill Screen, 16:9

[video] aspect_ratio = "auto"RECARBON_ASPECT

Brightness

Lighter or darker shadows and mid-tones, a gentle step at a time, as a TV's brightness. Black and white stay put. 0 is the original picture.

Default 0 · -5 to 5

[video] brightness = 0RECARBON_BRIGHTNESS

Xbox 360 Display Gamma

The gamma ramp the game itself sets for a real Xbox 360's TV output: a little deeper shadows and brighter mid-tones, as on the console. Off: a flatter picture.

Default On · On, Off

[video] xbox_display_gamma = trueRECARBON_DISPLAY_GAMMA

Graphics

Anti-Aliasing

Smooth jagged edges (an FXAA-style pass).

Default On · On, Off

[video] anti_aliasing = trueRECARBON_AA

Upscaling

How the game's picture is enlarged to the window. Bicubic is sharp, bilinear softer. FSR 1 (AMD FidelityFX Super Resolution 1) keeps curves, wires and diagonals smooth when the window is much larger than the Internal Resolution (1x on a 1440p or 4K screen), for a little more GPU time.

Default Bicubic · Bicubic, Bilinear, FSR 1

[video] scaling = "bicubic"RECARBON_SCALING

Sharpening

Extra sharpness for bicubic and FSR 1 upscaling (for FSR 1, the share of its sharpening pass's full strength). 0 turns it off.

Default 0.3 · 0 to 1

[video] sharpening = 0.3RECARBON_SHARPEN

Anisotropic Filtering

Keeps roads and walls sharp at a distance. Auto: 16x on a dedicated GPU or an M-series iPad, 4x on other integrated ones.

Default Auto · Auto, Off, 2x, 4x, 8x, 16x, Original

[video] anisotropic_filtering = "auto"RECARBON_ANISOTROPY

Mipmaps

Use the game's smaller textures in the distance, so they don't shimmer.

Default On · On, Off

[video] mipmaps = trueRECARBON_TEXTURE_MIPS

Internal Resolution

Render the 3D scene above the 360's 720p. 1.5x is 1080p, a little over half the pixels of 2x. Auto: from the screen (1440p: 2x, or 3x2 filling an ultrawide).

Default Auto · Auto, 1x (720p), 1.5x (1080p), 2x (1440p), 3x (2160p)

[video] internal_resolution = "auto"RECARBON_RESOLUTION

Audio

Master Volume

The volume of all game audio.

Default 100% · 0 to 100

[audio] master_volume = 100RECARBON_VOLUME

Mute

Silence all game audio.

Default Off · On, Off

[audio] mute = falseRECARBON_MUTE

Mute in Background

Silence the game while its window isn't focused.

Default Off · On, Off

[audio] mute_in_background = falseRECARBON_MUTE_UNFOCUSED

Input

Stick Deadzone

How far a stick moves before the game sees it. Raise it if the car steers by itself.

Default 8% · 0–90%

[input] stick_deadzone = 0.08RECARBON_DEADZONE

Trigger Deadzone

How far a trigger is pressed before it counts.

Default 2% · 0–90%

[input] trigger_deadzone = 0.02RECARBON_TRIGGER_DEADZONE

Vibration

Controller rumble.

Default On · On, Off

[input] vibration = trueRECARBON_VIBRATION

Controls

One row per Xbox 360 control, each with two keys. See Controls and the Garage.

Controller

Advanced

Asynchronous Shaders

Skip an object for a frame or two while its shader compiles, instead of stuttering.

Default On · On, Off

[advanced] async_shaders = trueRECARBON_ASYNC_PIPELINES

Performance Overlay

Show the frame rate and frame time in a corner of the screen.

Default Off · On, Off

[advanced] performance_overlay = falseRECARBON_PERF_OVERLAY

Advanced also has Save Bug Report, Check for Updates, the build's version and commit, and the legal notice. The footer's last button is Quit Game, which asks first.
