I'll second the recommendation for FSLTL. Only time I've seen something odd with it is if the plane was something odd or likely had something wrong in its ID info on the other user's side. Bonus for it being free as well.

I run frame gen (x2 only due to my card) on a 9950X3D and 4090 at 3440x1440 ultrawide. This allows me to run capped in Nvidia control panel at 80fps and most of the time hit that with my settings (depending on the aircraft). If I fall below about 45fps my monitor falls out of Gsync and I noticed that a lot more when looking around the cockpit than any potential FG artifacts of which I've never seen any in MSFS/MSFS 2024. Yes I know what they look like, I tried FG in Starfield once when support was added and quickly turned it off as artifacts were immediately obvious.

Since it immediately pops back when using the mouse I'd suspect a binding issue, though it seems odd to happen at the same time in both sims, and I'm assuming any aircraft in 2024 or have you only tried one (mentioning since 2024 can have per aircraft profiles if you didn't set one as the global default). You could try searching that throttle axis you're trying to bind in each of the devices in the mapping screens to see if one of them accidentally had a binding added. You could narrow it down by just checking devices with an axis or an always on toggle switch such as the ones on the Honeycomb controllers where it flips between 2+ positions and isn't just a momentary push button. Since it IS happening in multiple sim versions though, follow "flyforever's" suggestion of checking the axis in the windows game controller window first to make sure it's actually working.

Since you have BATC why not just turn on traffic injection but turn off the actual live traffic stuff? I haven't used the app in a bit (no time for simming recently) but I believe it has sliders for all the actual live traffic in addition to the parked ones. So you could just have it inject parked aircraft only I believe.

Something else to look at is if you're running re-shade. I ran into this issue the other day when I installed it for the first time after getting Atmos for 2024 to use the two together. Reshade would instantly cause sound and sim stutters together constantly. Ended up just uninstalling it. I've made it without stuff like re-shade this long. Didn't seem like it was affecting FPS on my 9950X3D and 4090 but the sim didn't like something about it.

They just dropped a note in their discord announcements it will be next week.

Yeah that's why I said the RNP type and I think they were specifically talking about the RNP types that have the arc in them similar to a more traditional radio based approach that has a DME arc. In a sim setting though they need to have some way to keep a user from either using those or just prevent the aircraft systems from freezing/crashing if the user does pick one. Instead, at least during the v1 days it would potentially crash the systems (or maybe the sim itself? I never tried one just read about the issues and it's been a while) and their response was the typical Aerosoft at the time of "the airplane can't do those, it's on you to know that and not pick them".

It cannot do RNP. Early in V1 days for 2020 people were reporting crashes in the MCDU etc and it turned out people were trying to use RNP approaches. Their response was "the real aircraft doesn't support these and neither do we" basically. Also some fluff about that "of course the real aircraft won't show these to the pilots" but they decided not to filter them out in some way in MSFS but also not do anything to prevent issues if you selected it. They basically said you might get lucky and it will work or it will just crash. The kind with the arcs were supposed to definitely cause crashes. I don't know if they did anything in V2 to mitigate this issue though as I haven't flown it in a few years now.

Full custom watercooling and a properly set up smart thermostat with a room sensor on my desk, works just fine.

I got a chance to re-test this weekend and found my problem. As I think I mentioned I had also installed Re-shade for the first time ever and used the Sealed Sky preset with Airbornegeek's settings for it. Turns out re-shade is the issue. I would have thought no problems running it on a 9950X3D and 4090. Not sure if native framegen or capped fps in the nvidia control panel can cause issues with it maybe. Before reinstalling it to test I recreated the same flight as the other day and one at a time after verifying no issues I turned on simlink, navigraph charts, then finally Atmos Core and it was smooth the entire time. Exited, installed re-shade, started the sim and configured the preset and did the flight again. Immediately after takeoff the stutter/hitch was back with none of the other programs running yet.

It's not an in sim addon like a plane or airport, it's a stand alone program so you have to launch it no matter where you bought from or what you installed it with. If you know how to add entries to the sim's exe.xml file you could probably edit it to add an entry to launch it with the sim though.

Interesting, they must have changed their plans since the official announcement I quoted was posted 25 minutes before that message. Well, that would definitely be nice if they put it out next week. Just a bit confusing since they said two different things within 30 minutes of each other.

Where did they say that? The quote I posted is directly from their announcement in discord this morning, I didn't see anything else in there about "next week". edit: not trying to come across as "difficult" just genuinely curious where they mentioned it.

You still need an Xbox account for the Steam version. There should be a part of the UI in the upper right of the screen to sign in if the user is signed out. If they don't currently actually have an xbox account they'll have to create one, probably externally at MS's website. Not really sure since I had one forever since I used to play some stuff on a 360 years ago but it's just tied to my MS account that I use with Windows etc.

Not sure where you got "next week" from? This is direct from their Discord announcement this morning
