Tips for everyone having this issue:
1-Reinstall, no, really, I was having 15-20 fps all around and once I reinstalled EVERYTHING now my game runs smoother than ever with over 45-50 fps in LEMD.
2-Do not get close to broken airports. LFPG (Charles de Gaulle) is broken, I get a max of 15 fps inside of it, as soon as I take off and get 3-5 milles away from it I am back to 50.
3-Make a clean install of your drivers, this solved the issue for a friend of mine
If nothing works, wait for a patch.
My specs:
RTX2070SUPER
