anyone having lag after update even with powerfull pc ? any clues ?
What kind of lag? Slow map movement? User aircraft lagging?
Alex
in open street map when zooming and navigate the flight plan in app .
Sry, for late answer. This forum somehow stopped to send notifications. 
What to do about the lag:
- Reduce map detail level back to default in menu
View. - Clear a probably too long user aircraft trail from menu
Map. - Do not use flight plans with hundreds of waypoints.
- Maybe exclude the LNM installation folder and settings folder (see manual for location) from anti-virus scanning.
Hope this helps.
