First i`ve try using the same 360 sense from the higher FOV game (Apex Legends, 107 FOV 4:3 based 800 DPI 1.1 sense)
It felt so wrong, because im a competitive player and very accurate with this sense, i'm very sensible to when it changes, it felt like the second game (Fortinite) was kinda like
an "ads with higher sensitivity" compared to my main sensitivity, so, my idea was, if i convert the second one, 64 FOV, as an ADS 0% monitor match from the first one, 107 ??? the result
was a much slower sensitivity, flicks was not doing their job, tracking was horrible, so i tried a 50% monitor match for the second one, felt obviously better, all aspects seems fine, but im not sure if 50% would be the most interresting value for this situation, any suggestion?
