FSTramp obviously came very recently to V7, covering from FSX to P3D4 and including XP 11.10 and above.
At my side, no FPS hit, but I limit them to 30 as I am flying MP nearly each week and do not want to overflow the servers with my data. LittleNavMap seems very promitting, and works also flawless under P3D4, displaying MP aircrafts etc...
Apart from the tariff politics, I like FSTramp very much, as I have been using FSNavigator for years, and because it is running inside P3D. But LittleNavMap seems to actually be a "killer"
