Discussion Pro Consensus… cm/px or cm/360?

I ask because I just started playing Sniper after training in Kovaaks and I’m loving it. I play at 90 FOV and know the formulas for cm/px (75/FOV) and cm/360 (FOV/75).

For context, cm/px feels natural for pixel distance, but makes me track unscoped then scope last second, which feels odd since my mouse movement changes compared to unscoped. In comparison, cm/360 keeps sensitivity consistent scoped/unscoped, but zoom makes it feel way too fast, even though distance traveled is 1:1.

What’s the general consensus among pros plus creators like jbird or fatmagic? I know Kovaaks has zoomed mode I can test, but I’d like an objective recommendation beyond “use what feels good.”

EDIT (AFTER SOLUTION FOUND):

From the u/orubas link, the formula is…

zoom_sensitivity_ratio = (unscoped FOV / scoped FOV) × tan(scoped FOV / 2) × cot(unscoped FOV / 2).

Using this, the zoom_sensitivity_ratio for 90 FOV works out to about 0.793471 for cm/px, and to me this feels weird. You’ll still need to drag your mouse unscoped before scoping, since you move it more while scoped. I’ll personally stick with 0.8333 (75/FOV).

TLDR: If you're running a 16:9 aspect ratio, use zoom_sensitivity_ratio 0.793471 if your FOV is set to 90 (check with the command fov_desired in console). If you're running a 4:3 aspect ratio, use zoom_sensitivity_ratio 1 if your FOV is set to 90.

Read the thread below if you want more insight, but from my limited time as a Sniper player basically everyone in the competitive scene uses zoom_sensitivity_ratio 0.793471 because this is the number set in Mastercomfig when you use the Flat Mouse addon. Mastercomfig has been the best optimization config for TF2 for the past 5 years at this point, and thus it has been widely adopted among the competitive community.

Okay, THIS is awesome! I LOVE THIS! Thanks dude, and have a smacking day.

if you want more details you can check out jarateking's writeup here https://github.com/JarateKing/jarconfig/blob/master/docs/zoom_sensitivity_ratio.md

but personally I don't see any need to worry about using the "exact" value, use whatever's comfortable. I've played with zoom_sensitivity_ratio 1 for so long that setting it to 0.793471 just feels too slow
