It's certainly a system by system try and see, kind of thing.

Yes, I exclude everything to do with sim in defender. It's my first port of call after installation!

My cache was on my NVME drive, so there's no where quicker for me to store it. It would be nice to know why turning it of reduces stutters, logically, you would think having it on would be more help. Not for me though.

The only downside I noticed to turning rolling cache off, was it took a little longer to load object textures, such as airport clutter and fsltl liveries. However ground textures were unaffected. I'll take that over the stutters everytime.

What a difference the cache dummy folder and rename makes! I have struggled so long with these stutters, I'd kind of resigned myself to it never being addressed. Am I now totally stutter free?, No, but it is night and day compared to what it was like before. Cockpit panning is much smoother. This cache trick has been around for some time. No idea why I never tried it before? Maybe I catalogued it as Snake Oil, I don't know. It certainly has made a massive difference to me. I'm lucky enough to 1GB broadband, which no doubt helps in streaming. Thanks all for your advice!

I have a 4090. I'm going to try turning off cache next using a dummy folder. Stu

Turning off VMX virtualisation didn't seem to make any difference. However, I had a little bit of time to play today and I've improved the situation of stuttering, although only Asobo can truly totally fix it. I have abandoned variable refresh rate use in my nvidia app settings. I've gone back to fixed refresh, V-sync on in nvidia app. In sim, I lock frames at 30 and use 2x FG to get 60 fps, my monitor is 60Hz. Looking at main thread timings, they are now down to 23-26ms at Heathrow in the Fenix with FSLTL traffic at modest settings, which is a pretty harsh test. This gives a little bit of headroom up to the 33ms max frame time before overloading the mainthread. I find if I run variable refresh rate, main thread is pegged to 33ms and stutters much more. I still get panning stutters in cockpit if the cache is allowed to empty. This is also true if you have pre-load cache set to ultra. I don't see any difference between high and ultra for this setting, textures eventually unload and stutters ensue when they reload after view change.

Found it. It was called VMX Virtualization in my BIOS. I'll see how things go. Cheers

I'm an Intel/Nvidia user, not sure they would appear in my bios. I'll take a look though.

It's worth a try, thanks for the advice!

My graphics settings are a mixture of Ultra and high and medium for airport clutter. 24GB VRAM. 64GB of sys ram. No, I don't use addon linker. I use GSX, FSLTL with settings at about 33% of max. I use the Fenix, PMDG 737 and 777, never use default aircraft. I get stutters on arrival to an airport, yet departing from the same airport no stutters, except for the well reported cockpit panning stutters. My TLOD and OLOD are at 200, or 100 below 1000ft if using AutoFPS. Like I said, I can trace this stuttering back to SU2. Stu

What do you mean by turn 'virtualisation' off. I've never seen this setting? I don't use Moza or BATC , so that shouldn't be an issue. Stu

This has been an issue since SU2. It's never been fixed up to now. I tried the SU7 beta and I find the performance of that to be slightly worse than the current SU6. I have not found a cure for this. I have tried low to ultra settings, DLSS on/off, FG on/off. it makes no difference. AI traffic can make it worse and TLOD can make it bad, too. As you say, you can spawn into an airport and everything is smooth for departure, but arrive there, and it stutters like crazy when loading scenery and airport objects. I find AutoFPS to help if you set TLOD and OLOD to 100 below 1000ft, but if you have high terrain around your airport, the scenery looks out of focus and muddy if you set TLOD at 50, plus you notice the taxiway lines go blurry about 50 metres in front of you. We shouldn't have to do this though. Afterall, TLOD 200 is a medium setting. My system specs are in my sig.

I have to say, with the ongoing arrival and panning stutters, that are still ongoing in default airports for many, including me, I'm not bothering to purchase anymore addons for ms2024, at the moment. Addon airports just make already bad performance worse. I have Inibuilds Heathrow and Manchester, they stutter so badly, I uninstalled them. It's a miss for me.

Yeah, why not just fix the loading error?
