i9-9900K + 3080 Ti + 64 GB RAM - getting 60 fps in the PMDG 777 at the moment over Germany. Trying to scroll, move or zoom in/out on the map freezes Navigraph for 2-3 seconds before anything happens. Turning off ATC + TFC doesn’t really help. Performance was MUCH better before this update.
Update: freezes are on every zoom in/out, app basically unusable at this time over EDDF.
So it seems to depend on the amount of acft in the immediate area. EDDF had an event on VATSIM so it was pretty hectic and killed performance. Turning it off initially didn’t change performance but it solved itself after a minute or so. Haven’t seen the performance degredation after turning off ATC linger since then. This is the desktop app, yes.
The performance in charts.navigraph.com via Firefox has a similar performance degredation but it works a bit better than the app. Just scrolling around now as I fly - nothing scientific - but seems to be a bit less jittery / laggy when moving the map around and zooming in/out quickly.
