I don't see anything here that could be limiting you. Try doing frame generation X3 and tell me what FPS you get on the dev mode.

Here's a screenshot on FGx3.

Did you do a full reinstall of the simulator at any point when you upgraded to SU4?

No I’ve only done the one initial install.

As someone said before, it's not very helpful to fiddle around the settings without a plan. But just as an idea: when i upgraded my system to a 7950x3D, i was shocked by the bad performance. The culprit was the motherboard's virtualization setting. After deactivating this in the BIOS, the performance was the expected one.

I have to confess, that i am still on FS2020 with the 7950 CPU and a 4080 Super, so i cannot comment on the FS24 settings, but perhaps a closer look in to the BIOS might be a good idea.

Wish u luck,

Matthias

The performance drop with virtualization enabled should be zero or negligible. Probably when you had bad performance the sim ran on the CCD without the 3D Cache.

No, running on the 3D cores was fine, AMD driver controlled or via BIOS settings, both gave priority to the 3D cores.

I don't know, if is was due to a BIOS / MOBA problem or something else. I made two BIOS upgrades after that but was not in the mood to enable the virtualization back. I cannot remember exactly...i think, it was in the FsHUD Discord channel, where another user mentioned a similar performance problem, and disabling SVM mode in the BIOS did the trick for him, too. Might be a very specific problem of my MSI motherboard. Just an idea, as i said.

During the SU3 beta period they recommended a reinstall of the core sim, due to some underlying code changes. It appears to me that something may be stuck from the initial install. Unlike 2020, 2024’s client is small and easily reinstalled. I would try that and let’s see what result we get. 
 

 

The client is small, yes, but plenty of addons then still need reinstallation, no? Or how do you guys get the exe.xml back to where it was without reinstalling all those addons?

if you’re using add on linker, it’s really easy to just enable your addons. That leaves just payware aircraft, autofps, and GSX for me. Which is just a matter of relinking it. 
 

The entire process takes minutes. It also outweighs the benefits to having a smooth running sim for me. 

Relinking? PMDG etc. need a full reinstall, no?

I have a folder that stores all my MSFS add-ons but it's not even inside the MSFS folder hierarchy.  Let's call this folder c:\MSFS-Addons.  Then I have the PMDG Application set to save the PMDG 737 (or PMDG 777) to c:\MSFS-Addons.  For example, I have the PMDG application save the 737-800 to c:\MSFS-Addons\pmdg-aircraft-738. Then I have Add-On Linker read my add-ons from c:\MSFS-Addons. For example, to read the PMDG 737-800, I get Add-On Linker to read the folder c:\MSFS-Addons\pmdg-aircraft-738.

No matter how many times I install MSFS 2024, or MSFS 2020, I don't have to reinstall any add-ons, including the PMDG 737.  I just have Add-On Linker recreate the virtual folders in my Community folder.

Remember that Add-On Linker merely creates virtual folders inside the Community folder. So you don't really have to reinstall anything, because you can have Add-On Linker recreate the virtual folders with a click of a button.

Hence, after you reinstall MSFS 2024, just get Add-On Linker to recreate the PMDG 737/777 virtual folder in your Community folder.

That was a wise decision. I only have those addons without installer linked with AddonLinker. All addons coming with an installer are installed directly into the sim...

Regarding the exe.xml, correct me if I'm wrong but it is not over-written when you install a new SU

At least I don't think I've ever had to re-create it or re-install things that put items in there (like TDS GTN for example).

Still I do back up that file just in case.  And with a beta install (SU4), I'd be even more vigilant.

Sometimes something is conflicting relinking after an update if the "work folder" is not cleared on your local drive  for plane addons

I have not had that problem with Add-On Linker before.  For me, I can always get Add-On Linker to clear my Community folder with a few clicks, and then generate the virtual folders in my Community folder with a few clicks. I haven't encountered the problem that you are encountering.
