Il2 had better icon and dot system configurable by the server, i myself never had any issues spotting in il2 and you could do it at normal FOV, in DCS it feels pointless even trying at normal FOV. Usually we just had friendly icons only with player name, so comms on a public server wasnt a confusing mess.
Thing is i can actually spot targets at really long range, i have much harder time seeing the people closer in, older games systems to account for the limitations of playing through a monitor and that has not changed.
