Just for clarification…
Vapour is produced when the air pressure rapidly drops below the air’s limit of saturation, producing the same effect as a cloud.
Condensation is produced when you pour an ice cold beer into a glass on a warm humid day.
Over-simplified? Yes, but you get the point.
Contrails and vapour trails are very similiar and I expect well within the capabilities in the sim currently. If they are implemented, I strongly agree that they MUST be done right or it will just be cheesy. IRL the kind of vapour trails you are depicting are VERY short lived and only exist in those limited zones of extreme low pressure during specific maneuvers.
It isn’t uncommon to see them appear within wingtip vortices, especially heavy jets, on takeoff. These can survive far longer and are a good indicator of wake turbulence, another effect that needs to be implemented.
Respectfully, I suggest editing your title to reflect a desire to see puffs of vapour on your wings and not beads of sweat on your beer.
