I don't mean to hijack this thread but I have the same question and didn't think it warranted its own post, and I've been reading online and haven't really found a straight answer (or an answer I can wrap my head around.)
I just upgraded from 1080 24" to 1440 27". My understanding is that resolution does not affect sensitivity, however it seems like monitor size does according to the calculator. I'm just trying to figure out which setting I need to change.
For example for COD Warzone, when I leave everything in the calculator as is (hipfire/look is set to 360 distance) and only update the monitor size to 27", the ADS becomes 0.89 and sensitivity/360 distance remain unchanged, then if I change the fov to ~106 from 96 it brings the ADS back to 1.0.
However, if I change hipfire/look to MDH 75% (fov 96), the ADS remains at 1.0 but the 360 distance is increased and sensitivity is changed to a smaller value.
I Feel like there's more than one way to skin this cat. I'm assuming the easiest method is bumping my fov to ~106 and I'm good to go. Or I could change my ads to .89 for everything. Or I could reduce my sensitivity but that raises my 360 distance which I think is the worst route. Or I'm doing the calculations wrong. Or I'm over analyzing and should just leave everything alone. Any input is appreciated, thank you!
