Rotational Aim Assist Strength is 60% and Tracks 2.5 Hitboxes

With zero right stick input, the rotational aim assist (RAA) moves 60% of the distance the target moves when the RAA engages. In other words, for every 10 units a target moves in the aim assist bubble, the RAA will move 6 units. This strength is the same on both Warzone 1 and Warzone 2.

# Evidence of 60% RAA Strength

To measure, a target is recorded moving across the aim assist bubble. Then, distances traveled are measured using two different screenshots showing a start and an end. The distances measured will not be perfect because of the nature of the game world being projected onto the player camera, but it is good enough to gauge RAA strength.

Here are screenshots comparing the distance the target and reticle move for mw2022 (warzone 2) with zero right stick input. The distances traveled are 166 pixels for the reticle and 279 for the target which works out to about 60% strength for RAA. The distance the RAA moves is highlighted in green and the distance the target moves is highlighted in purple. The screenshots are taken from [https://www.twitch.tv/bluex/clip/ConsiderateSuspiciousAnacondaWTRuck-SUiQxxePr2PrtFNZ](https://www.twitch.tv/bluex/clip/ConsiderateSuspiciousAnacondaWTRuck-SUiQxxePr2PrtFNZ).

The PC and console RAA strength for warzone 2 are both the same as demonstrated by hecksmith here: [https://twitter.com/hecksmith\_/status/1701668730898469019](https://twitter.com/hecksmith_/status/1701668730898469019)

Here is a screenshot comparing the distance the target and reticle move for mw2019 (warzone 1). The reticle moved 166 pixels and the player moved 279 pixels which works to about 60% RAA. The distance the RAA moves is highlighted in green and the distance the target moves is highlighted in purple. This is taken from the 3m28s example from hecksmith’s video here: [https://youtu.be/frjx63T5FQU?t=208](https://youtu.be/frjx63T5FQU?t=208).

The RAA strength of 60% may have been in cod for a long time. Here are 60% distances measured from a video demonstrating RAA for COD: Advanced Warfare (2014): [https://twitter.com/hecksmith\_/status/1704174637381263408](https://twitter.com/hecksmith_/status/1704174637381263408)

# 60% RAA Tracks 2.5 Hitboxes

When a target moves across a reticle while aim assist is activated, the player is not moving, and there is zero right stick input, the reticle will be inside the target hitbox (i.e. track) for a total target traveled distance of 2.5 hitboxes.

This can be derived through basic math. After a target has moved 1 hitbox, the 60% RAA will follow for 0.6 hitboxes, meaning there is still 60% of the target’s hitbox left to track. After the target moves another hitbox distance, the 60% RAA will have moved another 0.6 hitboxes, meaning there is still 20% of the target hitbox left to track. The target must move an additional 0.5 hitboxes to have the RAA reticle stop being inside their hitbox.

The formula for the amount of hitboxes tracked with zero right stick for an RAA strength (expressed as a decimal) is:

1/(1 – RAA\_STRENGTH)

Without RAA, the reticle would be inside the target hitbox for a total target traveled distance of 1 hitbox.

This phenomenon can be measured and verified experimentally.

The reticle tracked the target moving across its reticle in mw2 (2022) for a total distance of 2.5 hitboxes in this video: [https://twitter.com/hecksmith\_/status/1701668730898469019](https://twitter.com/hecksmith_/status/1701668730898469019).

Here is a screenshot showing the total distances traveled relative to the hitbox. Some may quibble on where the right or left edge of the hitbox should be, but I chose what could be easily seen on video with the edges of the head and back. Whatever hitbox edges you choose, the result proportionally will be the same.

If the reticle starts in the direct center of a target with 60% RAA and zero right stick, then the target will need to move left or right a distance of 1.25 hitboxes to move outside the reticle. This is as if their hitbox was actually 2.5 hitboxes wide. Without RAA, the target would need to move a total of 0.5 hitboxes left or right. Here, the target’s hitbox is 1 hitbox wide. This specific scenario means the RAA is effectively aiming at a target 2.5 times fatter than without RAA.

I speculate that in a corridor that is <= 2.5 hitboxes wide with the right conditions, horizontal movement alone may not be enough to “break” the RAA within that corridor even if the RAA is using zero right stick. The player would need to place their crosshair on the edge of the corridor while engaging aim assist, the target would need to strafe across the reticle into the corridor, and the target may surprisingly not be able to move the edges of their hitbox outside the reticle even with zero player right stick by moving horizontally inside that corridor.

# Conclusion

The RAA strength in call of duty is 60%. 60% RAA can track 2.5 hitboxes with zero right stick.

This methodology could be easily used to measure the strength of RAA in past call of duty titles to verify the claims that the AA has gotten stronger or stayed the same. Keep in mind that there are many other factors such as aim slowdown, AA bubble size, AA activation distance, response curves, target speeds, input lag, display refresh rates, and so on that can affect perceived RAA strength.

Apex’s console RAA strength of 60% may have been inspired by call of duty. ottr has made a great video on visualizing RAA strength in apex and what happens if you change it to values like 100%: [https://youtu.be/pTsQGi4-FuE](https://youtu.be/pTsQGi4-FuE). A lot of the information here for RAA likely applies to cod as well.
