100 feels "too high", and 50 allows you to zoom for ages, I use 75 for my ratchet flying scoutsman rounds although have found between 75 and 100 to feel and work the best as it prevents being stuck in the air while also stopping highly skilled players from slaughtering the map in 2 secondsIt is just as it says - server gravity set to 100 or 50
Easy Peasy, but a lot of fun
