Same FOV means possible exact same sens?

Hi,

I am trying to understand how MDH% works, correct me if I am wrong.

So mouse movement to a specific pixel on screen form the screen center is not the same between games because how 3D world projected to 2D screen is different between different FOVs. For instance, horizontal "angles" are mapped/scattered/distributed differently into 2D horizontal line with different FOVs, which makes mouse distance for flicks different.

This makes me believe:

1. Even in one game, when I do flicks, mouse movement distance of 0-90% monitor distance is not exact equal to 9x mouse movement distance of 0-10% monitor distance right?

2. When I have the same FOV between games, I should be able to find the exact same sensitivity that mouse movement for every screen 2D pixel to pixel is the same right?

But when I set BFV ads(1x) FOV exact the same as my CSGO hipfire FOV(checked on the converter page, both HFOV are 106.26), I found the output sensitivity different generated from different methods: 360, MDH0%. MDH100%. What part is wrong with my understanding?

Sry for my English,

Thanks in advance.

1. There is no correlation at all of "9x mouse movement" from a setup of 10% monitor distance to find 90% monitor distance since the image is distorted - it is not linearly scaled.

2. Correct - it will be the same between games - only if they use the exact same projection method, the exact same FOV, the same 360 distance, and also the exact same rotational pivot point.

BFV 1x ADS actually has a slight zoom compared to it's hipfire setting (i.e it's not actually 1x) also the Frostbite engine's 1P camera is physically based in the player model's forehead (who leans forward in stance), but then the player model's pivot point is also central between his feet. This puts the camera slightly in front of it's own pivot point compared to Source or Unreal games (i.e it works a bit more like a 3P camera does than is usual for an FPS game). It's a tiny difference but it's slight differences in design like this that can make the resulting measurements feel ever so slightly different too.

Thank you for your kind and detailed reply.
