ARC Raiders ​
Overview ​
The IBRA ARC Raiders Tool is an interactive CLI menu with two options:
| Option | What it changes |
|---|---|
| GameUserSettings.ini | Resolution, fullscreen mode, FPS cap, graphics quality, DLSS/FSR, Reflex, motion blur |
| Input.ini | Mouse smoothing and acceleration (disables both) |
INFO
These configs are a starting point for performance. Settings are subjective — what works on one PC may need tuning on another.
TIP
Launch ARC Raiders at least once before running the tool so the config folder exists.
