Achieve identical muscle memory across all sights. Match your 1.0x holographic and 2.5x ACOG telescopic ADS sensitivities using Ubisoft's focal distance formula (0% or 133% Monitor Distance matching).
Why do ACOG sights feel slower than 1.0x sights in Rainbow Six Siege?
Because higher magnification reduces your visual Field of View (FOV). If you keep the same physical rotation angle, the screen image zooms past much faster, creating visual disorientation. The 0% Monitor Distance match slows the degrees-per-inch slightly so that micro-adjustments near the crosshair feel 100% identical in hand-eye coordination.
What is 0% Monitor Distance matching vs 133% Monitor Distance matching?
0% Monitor Distance matches rotational sensitivity right at the crosshair center—perfect for small tracking adjustments and headshot snaps. 133% Monitor Distance matches sensitivity at the 4:3 boundary of your monitor—better for wide flick shots toward the edges of the screen.
