R6 ADS Calculator

1. Enter legacy ADS.Use your saved single ADS value from before Shadow Legacy (1–100). Do not enter a current Standard or per-scope ADS value.
2. Set FOV and ratio.Enter your in-game vertical FOV and configured aspect ratio.
3. Apply and test.Copy the results into each scope slot, then verify the feel in the Shooting Range.

In the legacy system, one ADS sensitivity governed the different scopes. Shadow Legacy introduced independent settings for each scope magnification. This tool reproduces the eight scope entries in Ubisoft's Y5S3 migration guide.

Ubisoft provided a conversion formula so players could migrate their existing feel rather than starting from scratch. The formula accounts for how zoom magnification and field of view interact to change the perceived speed of crosshair movement.

The conversion has three stages. First, your vertical FOV and aspect ratio determine the horizontal FOV. If the horizontal FOV exceeds 150 degrees, the vertical value is capped to prevent extreme distortion. Second, each scope's FOV multiplier scales the adjusted vertical FOV to represent the narrowed view through that optic. Third, the ADS multiplier for each scope is divided by the resulting FOV adjustment and multiplied by your legacy value.

In formula form:

HorizontalFOV = 2 × atan(tan(VFOV / 2) × AspectRatio)
FOVAdjustment = tan(FOVMult × AdjVFOV / 2) ÷ tan(AdjVFOV / 2)
NewADS = ADSMult ÷ FOVAdjustment × LegacyADS

All angles are converted between degrees and radians internally. Results are rounded to the nearest integer and clamped to the game's accepted range of 1–200. Ubisoft published this method in their Y5S3 ADS sensitivity guide.

These are the constants published for Ubisoft's Y5S3 migration formula. This table documents that historical model, not a current inventory of available scopes.

The formula produces a mathematically consistent starting point, not a guarantee that every scope will feel identical to your legacy setting. Perception of speed changes with magnification, and personal preference plays a role. Some players prefer slightly faster high-magnification scopes for flick shots, or slightly slower low-magnification scopes for tracking.

Always verify the converted values in the Shooting Range. Fire at targets at varying distances, switch between scopes mid-engagement, and adjust by small increments if a specific zoom level feels off. The calculator gives you eight coherent numbers so you avoid rebuilding from zero.

Do I need to use this if I already set per-scope values manually?

No. If you have already tuned each scope to your liking, keep your settings. This calculator is for recreating a saved pre-Shadow Legacy ADS setting.

Does the calculator work for console players?

Ubisoft's original Y5S3 guide used 60° for consoles. Console FOV sliders were added in Y7S1.2, so check your settings before calculating. This tool reproduces the historical migration formula; test the result in-game.

Why do 1.5x through 5.0x all return similar values?

The ADS and FOV multipliers for those scopes are close in ratio, so the formula produces similar sensitivity values. The differences become more pronounced at the extremes (1.0x and 12.0x).

What aspect ratio should I select?

Use the game's configured aspect ratio, which may differ from your monitor's native ratio. The aspect ratio only affects the result when it pushes the horizontal FOV past 150 degrees.

Can I convert back from per-scope values to a single legacy ADS?

This calculator only converts from legacy to per-scope. A reverse conversion is not part of the official Ubisoft method and is not supported here.
