If that is the case and since it's Unreal Engine based from what I can gather, the correct factor is likely ~0.37718 or ~0.37714 depending on how they implemented the sensitivity. Once I get access to the game we will know for sure
I’ve been told that Marvel Rivals is essentially OW2 sens multiplied by .375 for anyone trying to do a somewhat accurate conversion while we wait.
Example 4 sens in OW2 would be 1.5 in Marvel Rivals
