📋 Step-by-Step Instructions

Step 1: Step 1: Set Raw Input & Default Multiplier

In Rainbow Six Siege Controls settings, turn 'Raw Input - Mouse' ON and verify Mouse Sensitivity Multiplier Unit is at the default 0.02 (in GameSettings.ini).

Step 2: Step 2: Calibrate Base Hipfire (V/H)

Set your Vertical and Horizontal sensitivity between 8 and 14 for 400 DPI (or 4 to 8 for 800 DPI) to ensure comfortable 180-degree flicking on your mousepad.

Step 3: Step 3: Enable Advanced ADS Sensitivity

Switch ADS sensitivity from Standard to Advanced to unlock individual slider controls for 1.0x, 2.5x (ACOG), and 3.5x scopes.

Step 4: Step 4: Input 1:1 Focal Distance Multipliers

Set 1.0x to 58 (matching 1:1 monitor distance coefficient), 2.5x to 89-98, and test recoil grouping in the Shooting Range against moving targets.

❓ Frequently Asked Questions

What ADS sensitivity is true 1:1 for 1.0x scopes in Siege?

An ADS value of 58 on 1.0x scopes provides an exact 1:1 360-degree rotation distance to your hipfire sensitivity at 84 Field of View (FOV).

Why do pro players like Spoit use 400 DPI instead of 1600 DPI?

Pro players often use 400 DPI because it delivers higher physical granularity on large mousepads, preventing microscopic micro-jitters during long-distance pixel peeks.
