Welp, you can't really correlate both measures since one is linear while the other is angular

Yes. What is wrong with subpixel movement anyway?

FPS doesn't influence sensitivity.

Once the game gets a "count" from the mouse driver, the camera will be reangled. Sensitivity sets how big this angle is. There is nothing special to it.

TLDR -
Teamwork is where players function by themselves, but their effectiveness is multiplied when they work together. Not a checklist of "did we bring a healer so we can start playing?"

@tehmoriz
My vFOV is setted on 110, what hFOV does that represent ? (I'm terribad at trigo ...)

My screen resolution is 1920x1080, on a 21.5" widescreen, and my eyes are roughly at 50cm away from the screen.
EDIT: Googled it, and if I'm not wrong that would represent 137 degrees.
It felt weird to play like this after a 4 months hiatus but now it feels perfectly fine.

I'm a battlefield player, good sir. I don't play metro.

PC is no longer PC master race. It's PC mustard race, because consoles need to ketchup :'D

### Quoted from "Riesig"

DICE gave so much into making commander better, but lemmings be lemmings I guess.

### Quoted from "MrT3a"

As a good guy that don't want to use overly glitched weapons, I'll quit using the MTAR and switch to the ACWR until it's fixed

The world needs more people like you

+1, I think we're all in agreement that more MrT3as would be an awesome thing
Although if that was the case they'd use up so much of the world's awesome that there'd be none left for the rest of us!

yes, I know, I'm a big-ass hypocrite

If default sensitivity is something like 0.5 for default, then it most likely is simple

### Source code

1

mouse_delta_x * sensitivity
and same with y. I am not quite sure but if you use mouse input coming from Windows this is how many "pixels" your invisible cursor moves on screen while as raw input is more precise floating point values, hence giving better accuracy especially on lower sensitivitys (not to mention zero outside effect on cursor movement).
If they don't have any fancy methods made by themselves in engine, then game moves look_at vector based on given values. Math behind that is something at least I can't do because some suggest one should use some kind of compelx numbers I haven't studied yet and simpler algorithms I find don't explain themselves ._.

More info on this (like source code)? The game appears to simply transform mouse movements linearly to changes in the camera angle with sensitivity just being a constant multiplier in this transform. Or is it more complicated?

And re complex numbers, (almost) exclusively easy stuff: Complex number - Wikipedia, the free encyclopedia :>

I am not even familiar with matrix stuff yet D: . These Quaternions are what I was looking for (forgot the name on that post).

I don't have source code for this and it's just a hunch, however D3D seems to offer similar lookat functions like in OpenGL so it's possible they're using this, but it could be possible they calculate matrix stuff themselves etc. No idea. I imagine it would be easier with just angles because then you could just add and substract mouse input (implying up-vector stays the same), but if you have this focalpoint vector you have to do all these fancy math stuffs like rotating in relative to certain axis etc.

If you're so worried about tweaking for accuracy then you need to upgrade your mouse, first and foremost. The G500 has a lot of problems with precision.
