"I chose both PRIVATE and PULICc Network"
Re. New Nividia App and firewall settings:
When I started MSFS2024 for first time the new Nvidia App didn't recognize the game so not seeing any spesific MSFS2024-settings.
When I had to re-install MSFS2024 I "discovered" there is a popup in relation to the Windows Defender FIREWALL-setting that asks for permission:
"Do you Accept MSFS to connect to:"
[ x] Public Networks
[ ] Private networks
<< So I chose both PRIVATE and PULICc Network,
and discovered that MSFS2024 graphic settings now was avaliable inside Nviodia App
BUT: I don't know for certain that it wa this firewall-tuning that this DID the trick, as the Nvidia app also updated itself during process...
(search for "Let an App through the firewall" in your Windows search ... (Control Panel / All Apps / /Windows Defender Firewall / Allowed Apps / ... )
