Curve Editor
50-point Catmull-Rom curve editor with 5 presets, free-hand drag editing, and per-game curve recommendations for ReaSnow S2.
Aim Tuning
Mouse sensitivity, DPI, report rate, curve editor overview, and controller dead zone settings for ReaSnow S2.
This section covers everything related to mouse aim tuning on S2 — from basic sensitivity setup to the 50-point curve editor and dead zone configuration.
Before You Tune
Get these fundamentals right first:
| Setting | Recommendation |
|---|---|
| Mouse DPI | 4000–16000 (5000 recommended) |
| Mouse Report Rate | 250–1000 Hz (500 Hz recommended) |
| Mouse Acceleration | OFF (disable in mouse software) |
| In-Game Sensitivity | MAX (let S2 handle the curve, not the game) |
Set your mouse to the recommended DPI and report rate using your mouse manufacturer’s software or onboard DPI button before connecting to S2.
Sensitivity Parameters
These are adjusted in the APP’s Mouse Advanced Settings page.
| Parameter | Range | Default | Description |
|---|---|---|---|
| HIP Sensitivity | 1–5000 | Per-config | Sensitivity when not aiming down sights (hip-fire) |
| ADS Sensitivity | 1–5000 | Same as HIP | Independent sensitivity when aiming down sights |
| Vertical Ratio | 10%–200% | 100% | Vertical sensitivity as a percentage of horizontal |
| Minimum Speed | 0–100 | 0 | Ignores mouse movement below this threshold — filters out micro-jitter |
⚙️ Advanced: HIP and ADS each have independent sensitivity values. This lets you keep fast turning while hip-firing and a slower, more precise speed when scoped in.
Response Curve
S2 uses a 50-point Catmull-Rom spline curve that maps physical mouse movement to in-game stick output. Each point is a control node you can drag to reshape the response.

Dead Zone
If your aim drifts when you are not touching the mouse, or the crosshair moves too abruptly from a standstill, adjust the dead zone. This is also where you fine-tune the controller stick dead zone for authentication and gameplay.

Aim Assist
S2 offers two aim-assist algorithms for games that benefit from stick-acceleration-style reticle friction:
| Option | Behavior |
|---|---|
| A | Standard assist curve |
| B | Alternate assist curve — try this if A feels too aggressive |
| Off | No aim assist applied |
⚠️ Warning: Aim assist behavior varies by game. Test both options in your game’s practice range before committing to one.
Saving Your Settings
All aim parameters are automatically synced to S2’s RAM as you adjust them. To make settings permanent across power cycles, tap Save to Flash — otherwise changes are lost when S2 powers off.
Deadzone Settings
Stick dead zone and trigger threshold configuration for ReaSnow S2 — per-game differences, inner/outer dead zone, and precise numeric input.
