Horizon Zero Dawn

Patch 1.04 fixes the negative acceleration issue with variable framerates. There's still smoothing and the occasional doubling of mouse reports, but it works a lot better now.

Is 30fps-capped prone to smoothing and occasional doubling as well?

Doubling yes but not smoothing.

Hello, accedently bumped on your site and kinda lost here. Is your software capable to remove that smothing and doubling? Or maybe you know any other way to do it? Aiming is so terrible in this game I become dizzy in a minute.

This isn't software that does anything to your game, it's a calculator to match your sensitivity to other games and some tips and tricks to get rid of sensitivity issues if possible. For Horizon Zero Dawn there will be issues no matter what you do though, the game devs need to properly fix the input.

Is there any kind of formula or anything to work out what the Y sensitivity value should be to match the X value?

The output should tell you the correct Y value if you select it in the "Aim" option. This particular game has a lot of issues with sensitivity though, but using the calculations you can at least get the base sensitivity correct.
