@Jon Clarke since the FPS limitation is on the CPU side, are you running World Objects in MAX?

@Jon Clarke the performance has increased 'slightly' but still very bad when facing the problem area discussed. I am talking 18-20 fps (previously=16). The problem area southeast of the apt seems to have become a bit smaller. I get 35/40 with settings High at a major international airports like Frankfurt, Munich or CPH, to name some. In a small provincial airport like LIEO should be far above 40 fps on my system.. And I don't really subscribe to the 'clash'... it's an airport scneery. I have hundreds of them. None of them 'clash'..

@Jon Clarke shadows off makes a tiny difference. about 19fps instead of 16 when faceing the problem area in the southeast . Issue remains that someting is causing a huge CPU load. some more testing: *issue is for sure with the LIEO scneery. disabling this and using default airport --> no problems *disabling Ortho4XP tile --> no difference *disabling Ortho4XP OVERLAY file --> No difference This last line is important. It means that even when there are NO OTHER 3d OBJECTS in the scenery, apart from those included in this package, it still bombs. The frame rate drop due to CPU load is entirely due to objects from this package, not any conflicting scenery.

Attached are my settings. These are high but, as mentioned, they work fine for me elsewhere. log.txt is also attached. A/C is the Zibo 738 in this case. Other aircraft yield same results (i.e. INI A310) Log.txt

@Jon Clarke @vittoriogrecoUnfortunately the FPS drop is still there post-update. On my I9 10900 / RTX3080 / 32gb system (on 1440p) it drops to 16/17 fps when looking from the airfield to the area east/southeast of the airfield. so AWAY from the town but, as others have mentioned, to the tree area, or at least in that direction. The drop in FPS is sustained whoile lookign that way. Very similar to the previous poster.The FPS drop is due to CPU load, not GPU load. in other directions no problem at all. I've been panning around a lot and noting the frame rates. Bottom line seems the two heavily wooded areas to the east and southeast of the runway are to blame. Frams are worst when these are both 'in shot' , improving somewhat with only one, and clearing up when panning away. As mentioned, high end systems that handles the lagest and densest areas effortless, so little Olbia should be no problem at all. Work to do still!

scenery_packs.ini attached. @vittoriogreco using x-Europe but with Autogen disabled, SFD Global, Ortho4XP. System is I9 10900, RTX3080, 32GB ram, @1440x3440. Graphic settings are on high, mostly. scenery_packs.ini

There are some more issues with this scenery, unfortunately. There is unreasonably high CPU usage. (far above any major big-city hub airport, not good) and some autogen exclusion issues, see screenshots

Purchased your LIEO scenery. The marshallers seem to be missing, otherwise fine looking scenery. IM
