Closing the debate about scoped sensitivity multiplier

Important edit : For CS players, you may want to check this comment thread to find your horizontal monitor match. Also, if your CS scoped sensitivity is under 0.8189, multiply it by 0.9294379819.

So, there has been a lot of debate about what scoped sensitivity multiplier you should use in VALORANT. I heard about using 1.00, 0.82, or even using your normal sensitivity as the scoped multiplier. None of these values are completely wrong, but neither are they true.

Since mouse-sensitivity.com is not free to use, I made an online calculator to find out the scoped multiplier you should use, depending on the weapons you play with and the monitor match you want to use (the multiplier is NOT affected by resolution since VALORANT use a locked horizontal FOV of 103°).

The calculator : https://jscalc.io/calc/DOdocMexdQ5fvPiS

I based my calculations on these sources :

Wikipedia : https://en.wikipedia.org/wiki/Field_of_view_in_video_games

And this (very well made) post on mouse-sensitivity.com

Then, I verified my results with their converter and turns out it works just as fine.

So, how to use the calculator ?

First, select the weapon you want your perfect sensitivity multiplier to match with. Second, enter the horizontal monitor match distance you want to use. YOU USUALLY WANT TO USE 0% AS THIS DISTANCE MATCH ON YOUR CROSSHAIR (equivalent to 0.81.... on CS:GO, I think 1.0 in CS:GO is 100% horizontal match of a 4:3 monitor, so 75% of a 16:9 monitor).

Actually, since a zoom is basically narrowing your FOV, there is no "perfect" sensitivity multiplier : you can only make a specific distance on your screen the same distance to travel on your mousepad, whether you are using ADS or not.

For example, using 50% horizontal monitor match will make the mouse movement needed to flick to the middle between your crosshair and the edge of your screen EXACTLY THE SAME, regardless if you are scoping or not.

So, why 0% monitor match is considered the best ?

The answer is quite simple : the farther you are from the monitor match distance point, the greater the innacuracy will be. As you usually need to do very small flickshots when scoping, 0% is the way to go in most situations. Furthermore, THIS 0% IS THE SAME FOR EVERY SCREEN RATIO (4:3, 16:9, 16:10, 21:9 ...).

You can still use another monitor match if it doesn't fit you, I know many players who prefer to use 100% horizontal monitor match distance.

I strongly recommend you the post cited above if you're interested, it's a very good read.

I hope I didn't explained this too badly, please tell me if there are still a few points to be clarified.
