Same. Shortly after the flight began my FPS dropped from 50/60 to under 20 with persistent stutters. Changing to any other server returned to expected 50/60. On SE Asia flying out of view of “the gaggle” of other players … frame rates went back to normal.

Hello, StuxIT! I do see you often for the fly-ins.
I’m having the same issue the last two weeks Since SU2. Once everyone is in and we start it all goes south and grinds to a halt. Try as I might to change things I do not get any good results.
The only Add-On I am using is Bushtalk Radio ( @BU5HT4LK )
I suppose I’ll try a fresh install without adding in Bushtalk before next Friday.
Cheers and best!
You all seem to be lucky to me… My sim is not even able to download the SU2… It stopped after 199mbyte and never started again with a generic “there is a problem on our side” message. No information at all is provided on how to solve the problem on the official site(s)…
There are multiple CTD sources in SU2 that did not exist in SU1. One is a CTD that happens only near big cities, which results in the sim stuttering a few times then CTD with no error window. The other is the Device Hung error window which seems to be more random. Several suggestions to try below.
Disable Frame Generation
Disable Resizable BAR in BIOS
Disable Hardware-accelerated GPU scheduling in graphics settings.
Update BIOS (myself and multiple other people have found this eliminates the CTD near big cities)
- Using RegEdit, add the following 32-Bit DWORD Values
TdrDelay with Hex value of 3c
TdrDdiDelay with Hex value of 3c
to
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers

I’d argue that the sim should be robust enough to deal with “incompatible” addons by refusing to load them or portions of them if they can potentially cause an issue with simulator stability. At the very least it should output a log line explaining that there could potentially be a problem.
How is an end-user supposed to know whether or not a window texture on terminal 6 stand 871 of their addon is causing the simulator to stutter / crash / throw a wobbly ?
This whole “start it with no addons installed” is all well and good, but come on. Some people have hundreds of addons installed - are they seriously supposed to enable them one by one rather than have the sim maybe output a log when it encounters an issue or an increased rendering time?

Same here.
I have posted several times on SU2 Beta channel that My FPS when on SU1 was way better than SU2. But, they still release SU2 with a worse FPS and it baffled me.

Hi Kinneas2020,
thanks. I will deactivate everything with AddOnLinker before friday. Mount Everest might need full fps 
Maybe I will try a non-Marketplace plane.
With deleted LocalCache I assume my setup is pretty same as new.
Have a good week. See you in Nepal

Oh my! Sorry to hear that!
The priblem with some of the addons is while they are functional, so if the sim did check them, it wouldnt throw them out under your scenario, they are horribily optimised. Take the Ini 350 for example, its initial build was super bad and just ate system resources.
So no, having the sim refuse to start incompatible mods wouldnt work, as they can be compatible, but still break the sim. Which is also why yes, you need to uninstall every single mod, and test the vanilla game without any mods. If you still get issues, then its clearly the vanilla game at fault, and thats something Asobo can address.
The title to this thread should be After SU2 the sim is unusable on my system. This is because the sim is not unusable per se, for the vast majority of users. Which is not to minimise the difficulties the original author is experiencing.

Just want to say I had the same error message as the op showed in the first post and I using 2020. It got fixed straight when I reverted my AMD gpu driver back to March. The latest (May) caused this for me. (Yes, I see, that’s an Nvidia in that pc)
Thank you. But if I got the right post, it is a very useful video showing how to improve performance after the last update. My problem is that I’m not even able to download the update…
- I have the Micrsoft Store version
- I tried several time to update the sim, and after tenths ot tries finally the download started
- The download stopped suddenly after having downloaded 199.9MBytes out of 4.62GBytes, and after that I have been never able to restart it
- I receive a generic error message simply saying “There is a problem”
- From the page of the game (in MS Store) the error message is “Handle not valid (HRESULT: 0x80070006)”
- If I look at the details, the dialog says simply “There is an error and we are working to solve it. Try to update or come back later”. It makes no sense
- I tried also to update the sim from the XBox app, but the result is the same
- I updated the NVidia driver to the latest version (576.52)
- Windows 10 is up to date
- I tried also to disable antivirus, firewall, and even windows PowerToys, but the download fails
- No mods and/or addons
I could try to uninstall and reinstall from scratch, but I don’t know if I’ll lose my career progress or not (not mentioning the work to be done to reconfigure everything, including the peripheral)
Any suggestion?
Thank you anyway for your support
There are another few guys who are having a similar issue - it is in the bug reports have a look for it
I searched for “su2 download after:2025-05-07” but I wasn’t able to find something useful.
If you say that there is other people with the same problem I believe you for sure, but (my fault) I wasn’t able to find the posts…
Sorry for bothering you and thanks again for the your time and your support
After struggling through with SU3 beta for a bit and really losing the will to fly, I thought I’d give SU2 a go as I never did after it released
Loaded into inibuilds Heathrow in the A20N with photogrammetry and multiplayer off. Absolute slideshow setting up and taxiing with plenty of freezes. Took off and the flight went ok until AI ATC assist decided out of nowhere to request cancelling my IFR flight plan for no reason
Landed at Pyreegue Edinburgh II which was also a slideshow with several freezes both just before and after landing. Performance is just absolutely dismal on 2024 at the moment with the same flight on 2020 SU16 beta being absolutely flawless
It’s also still deleting logbook entries and occasionally removing random controller assignments. Really enjoyed SU1 but this is just horrible
Xbox series X
PS I’m going to go back to saying this constantly - get rid of static aircraft until we have an option to reduce them. Nobody is going to complain about empty airports when they run smoothly

Thanks again. But I have no “strange” entries in hosts file (if this is tha problem you intended to highlight to me).
And I was simply trying to update the SIM from an official version to another official version… I don’t know what to think…
Again, thank you for your help
Issue solved! Thanks to a suggestion of a Facebook user I tried to use a VPN connecting to a server in a different country, and the download started again…
Brilliant, I am very happy it is up and running - happy flying
