Sounds to me like Rolling cache has saved the data from the ground/airport, but, i haven’t seen your system up close and you claim it’s a good system with no hardware issues, so that automatically means game settings. If it’s only approach, i would guestimate it’s the terrain settings.
(although there have been many problems reported with the 3080 cards, but usually because of user errors in mistaking this sim/game for an fps shooter where more is better)
Also, what i’ve been through with many friends i’ve made through the years, is that, usually the settings of the simulator are too high, because many people are convinced this simulator should run at least 60 fps… but that merely only happens when the system running the sim is properly balanced. The idea of this particular series of Microsoft product has always been that Smooth is better than high fps. High FPS is nice for fast actioned shooters, not for a “reality based sim”. Hell, i remember a time where you’d be lucky to be able to run double digits. Yeah, i’m that old.
I’ll give you the example of my system:
i7 10700k (pretty good)
MSI MPG Z490 gaming plus (does the job, just dont update the bios, mistakes were made by msi)
32GB corsair DDR4 3200 (pretty good, but only about 12 ever gets used before the sim soils itself, probably memory leak of the sim or windows issue, still needs to be solved)
GTX 1080 (old, outdated, not upto pushing as many graphics as this sim desires)
Performance? Everything on Ultra or high, terrain on 200, rendering on 100… monitor on 75hz, fps ingame right now on 20fps (which actually locks me in at 25 fps) (normally on 30, which gives me 37,5 fps but it fluctuates alot more… apparently the next update will properly produce the frames that are set in the ingame menu, instead of cutting your hz into pieces, as 60fps right now in the ingame menu is actually 100% of your hz it’s trying to push. But if you have your monitor set to 144hz, yer only producing heat, not frames, as yer basically unlimiting your fps to what the system can handle, usually causing overheating and stuttering because of overrevving your system.)
Anyways, i’m astonished i get pretty good performance, nearly no stutters except when tight/quick turning… what i’m getting at here is: dont overrev your engine, check your hz on your monitor, check the fps… you want stable, not unstable dropping and rising of the graph in the imgame developer mode.
Oh, and i also have about 500something things installed, which includes Asobo things, third party things
and 150 mods in my community folder. This system should be stuttering, choking to say the least, but heavy addons like the 737 and the 146… nearly no stutters near major cities or big airports… yeah, aint i lucky huh?
Bluntly put, check and recheck your settings. Go for stable, not high, there’s alot to load every flight… once in the air, the data used by your system is lower than close to the ground, set the system up so that close to the ground runs smooth, then up in the air will be a breeze. The stutter when turning sharply, is basically the same as you trying to move the bookcase in your house, it just takes alot more effort when there’s books in there, then when it’s empty.
Hope it helps, if you want me to check with you, drop me a pm, i’ll invite you to my discord and help you diagnose… i’m not a miracle doctor, but i’ve booked some successes. All we’re really here for is the same great passion: flying.
