ISSUE DESCRIPTION

Description of the issue: Pilot camera rotation causes heavy stutter after 60 sec. of inactivity.

Seems like textures of scenery unloads from cache after timeout of inactivity, even if your aircraft doesn’t moving - very annoying after entering data in CDU, or just holding short.

I have tried to track of time, 55 seconds - everything is smooth, 60 - hell of stutter.

FREQUENCY OF ISSUE

Always

REPRODUCTION STEPS

  1. Load free flight, preferably in large airport (any complicated scenery) with graphics-heavy aircraft. It doesn’t necessary have to be community scenery/aircraft, but it will be better to show up this way. I can see issue even on C152, but PMDG737 or iniBuids A350 will show it more clearly.

  2. Go to the cockpit, look around with in-game camera;

  3. Wait for 60 seconds, try to rotate in-game camera for 360 in any direction.

I did little investigation of this issue, found two most significant factors of it’s common appearing:

1 - Scenery complexity - isn’t only the airport, but photogrammetry and quantity of city buildings also affects.

2 - Proximity to the shore - mostly large lakes and oceans/seas.

Example list of tested locations with this issue (testing method: load iniBuilds A340 on any suitable parking with “On APU” cockpit state preset, rotate camera for 360 degree to load scenery to cache, start chrono, wait for 60 seconds, try to rotate camera again):

Did not appeared:

DAAP, UNOO, KABQ, ZLXY;

Light (infrequent stutters less than 100 ms):

ZSPD, DTTA, Digital Design URSS, RDPresets LEGE

Moderate (repeating stucks for 300-500 ms):

EGPP, EKCH, LEBB, Digital Design LFLL;

Heavy (difficult to rotate camera with mouse, main thread stucks for over 1000 ms):

RJTT, lVFR-scenery LEBL, Verticalsim KTPA, Flightbeam KDEN;

(used default free streamed airports unless otherwise specified).

Also quantity of enabled scenery addons in community folder have affect, but it seems like overall performance degrading with it. Bug still exist even if only single tested scenery was enabled (linked to community folder).
