Is this the secret to sensitivity?

Competitive Discussion
Hello,

I have been toying around with different sensitivities and wanted to provide some information for your feedback and comments.

Firstly, as an avid viewer of streams one of the most common things I see people asking is what sensitivity should they use, what is the best sensitivity to use.

Certainly the absolute optimum sensitivity can be different for different games and heroes, and you may already have a preference due to muscle memory and such, but what about for first timers in OW, or those really wanting a change? let's focus on the overall picture, mathematically.

Firstly the basic formula is this

360 degrees in X cm = Maximum value CM Per 360 / DPI / OW Sensitivity OR

360 degrees in X cm = Maximum value CM Per 360 / OW Sensitivity / DPI (you get the same result whichever way around you divide)

An example and very common configuration would be 800 dpi @ 5 sensitivity = 34.63636375 CM per 360
(This is a configuration you will often see simply rounded to 34.63 or even 34CM per 360)

SO the maximum value CM Per 360 is the lowest OW sensitivity and the lowest DPI, which theoretical purposes is 1 sensitivity and 1 DPI which will require 138,545.455 cm to turn a full 360.

How do we know?

Well let's test the reverse of the formula from our configuration to see if we get the same value. The reverse of dividing anything, is to multiply instead.

34.63636375CM X 5 sensitivity X 800 DPI = 138,545.455CM

So from here we can now work out how changing sensitivity affects what actually happens.

For example if you've been trying 1600 DPI @ 2 sensivitiy you can work out 138,545.455 / 1600 / 2 = 43.295cm (rounded) Per 360

If you wanted to change your sensitivity to 2.3, how would that affect the actual changes that are happening?

138,545.455 / 1600 / 2.3 = 37.64CM per 360, we've now taken a full 5.6CM off a 360, we've decreased all required movements by roughly 1/8th, actually quite a large difference when you think about it.

It is here you can see that you can manipulate your DPI and your OW sensitivity to achieve smaller sensitivity changes as 2 to 2.3 at 1600 DPI is only 3 steps (2-2.1-2.2-2.3), if you halved your DPI to 800 you would need to double your OW sensitivity to match, and would then have 6 steps for the same results, allowing more increments (4-4.1-4.2-4.3-4.4-4.5-4.6) (2 doubled is 4, 2.3 double is 4.6)

So the final and ultimate question is, what would be the best overall sensitivity to work with.

Ultimately the easiest way to answer this would be, what sensitivity can achieve as close as possible to a 1 for 1 movement with the amount our hand moves to how much the actual camera turns in game?

For example
If our wrist sat on a pivot, and turned 360 degrees, what sensitivity is required that would then reflect the movement on the screen to be 360 degrees.

So going back to 800DPI @ 5 sensitivity = 34.636CM per 360, what we are actually looking for here is a sensitivity that gives us as close to 36CM per 360 to get what would be a full pivot on the wrist to reflect a full turn on the screen.

(36CM = 360MM / 360 degrees = 1)

The answer is (DRUM ROLL)
400 DPI @ 9.6 (138,545.455 / 400 / 9.6 = 36.07954)
800 DPI @ 4.8 (138,545.455 / 800 / 4.8 = 36.07954)
1600 DPI @ 2.4 (138,545.455 / 1600 / 2.4 = 36.07954)
3200 DPI @ 1.2 (138,545.455 / 3200 / 1.2 = 36.07954)

When you divide 36.07954 (360.7954 by 360) you get = 1.00220 mm per degree as close to a 1 for 1 movement reflecting how your hand actually moves to what you see on screen.

This is of course assuming you can only move your DPI in multiples of 100. The closest actual value in DPI would be 405 DPI @ 9.5 which gives 36.009 cm per 360 or 0.10002 cm / 1.0002 mm per degree.

The biggest question (unless i've missed something obvious here) in my mind is why 800 dpi at 5 sensitivity is one that is so common for pro gamers!

Thoughts?
me no understand me need more details me too stupid
The answer is (DRUM ROLL)
400 DPI @ 9.6 (138,545.455 / 400 / 9.6 = 36.07954)
800 DPI @ 4.8 (138,545.455 / 800 / 4.8 = 36.07954)
1600 DPI @ 2.4 (138,545.455 / 1600 / 2.4 = 36.07954)
3200 DPI @ 1.2 (138,545.455 / 3200 / 1.2 = 36.07954)
While lower "is" more accurate, there is no "key" sens everyone uses - its all a bit different, although at the lower end.

i just tried it its like x10 more difficult for me
Question. I am a complete newbie in this though.

This has always been bothering me. How are people able to use their whole arm to control the mouse on their mousepad and rotate so fast? I've always been using 'wrist' over whole arm ever since I touched FPS games.

When I finally got myself a gaming mousepad and switched to recommended dpi / sens settings to try it out (let's say 800 @ 4.8) for the first time, it was a drastic change. Movement felt extremely slow and really tiring to even do a simple 180 degrees turn.

So, is it just-- I don't know getting used to it and practice? How can people withstand that? After a while of playing, I could tell my wrist started to hurt.
@Marcin - It's wrist vs arm aiming. You'll need to retrain yourself to get used to that. You do end up having better control once you get used to it. I'm a wrist aimer myself and usually just grip my mouse harder when I need to track better. I personally don't think I'll ever get used to arm aiming because it's quite tiring to do.

What is your current DPI / Sensitivity?

Honestly it's just practice.

use your elbow or near elbow (the soft padded bit of your arm) to pivot the swing of your mouse to quickly turn.

It was foreign for me for about a week, then I started to get it. Much more comfortable now
Humans can only process information from eye (seeing the target), to brain (processing where the target is and where it will be), to hand (moving the hand to the estimated target location) so quickly:
800 dpi at 5 sensitivity probably reflects the highest sensitivity that allows those three to work most effectively.

In other words mouse sensitivity is a reflection of brain processing speed and hand eye coordination. Since we are all made very similar it would make sense that we would need to use similar mouse speeds.
Razor Synapse says to use recommended setting of 1600-1800 dpi.

default mice were / are 800 dpi for a long time.
I wish I could upvote this post twice, never thought of using the 36 cm to 360 degree conversion rate before

A long time ago I naturally settled at 800 dpi and 4 sense, i think i just got lucky
I'm confused. How is 36cm to 360 degrees important?

It's not
I use 4000dpi, 7 sensitivity on ow for aiming characters and 10 sens for characters like winston and mercy and doomfist. I have a mouse that i can change dpi with a push of a button so if i need to slow it down during gameplay, i can.

To those at 800 / 5 or close. Does the aim move really slow? Because when i use those settings characters can outrun my aim.

My suggestion is that this, or around this setting is what gives a close 1:1 ratio of hand movement to screen movement (assuming the 1920:1080 resolution)

36cm which is 360mm is 1:1 mm to degree ratio

So if you had your hand on a pivot and did a full 360, that would reflect a full 360 on your screen.

Imagine holding a gun with a laser, but despite you moving it at a certain distance, the laser moves further (or less!) because you have a different laser sensitivity to what your gun is actually moving.

I'm suggesting a 1 for 1, so if you move your hand 1 mm, you have 1 mm of movement on the screen.

Arm aiming is what people use to compensate lower sensitivity. Honestly your 360pcm must be around 5cm... I presume you're a wrist only aimer?

That is to say your whole arm never leaves the place it sits, only the wrist does the work. Nothing wrong with it, but it's found far more accurate to use your arm for large swipe movements and your wrist for fine tuning.

It also takes a lot of work off the wrist, from a physical and healthy perspective.

Assuming you use a 1920:1080 resolution, would mean you move 1mm in your hand and it moves around 7mm on screen, so your screen is turning 7x the amount your hand is moving every mm. I mean ... it's consistent so you can get use to it, but I don't think it's optimal.
So how does this work

console is seperate story, but similiar afaik

most go highest sensitivity and then buy raised thumbsticks, effectively getting a move more cm (or mm) for same accuracy. the max sens is just to compensate for slower gameplay of consoles

arm aiming simply works
