Ok good to know, I can just check G-Sync to be enabled for windowed and full screen. That doesn’t really help this problem though.
As I understand it you don’t need to enable both Vsync and G-Sync. You can enable them both since that would prevent tearing if your rate goes over the monitor refresh rate. Not a problem here. But since Vsync also adds latency a better thing to do is just cap your frame rate, maybe 2-3 fps under your monitors rate if you still see tearing. That works really nice in games with better performance like DCS where I can indeed go over 120. Not any help here though.
Yes those are all enabled
You didn’t need it with Windows 10 but with Windows 11 you need it or it won’t work well (I also have G-sync monitor).
Cheers
Why would that be different between W10 and W11? Honesty I don’t think I can tell the difference here but the Vsync off explanation is easier to understand.
This is pretty hard to follow
In DCS Vsync off looks very smooth to me.
As far as this game goes I think I have just discovered why FS2020 is being shelved. No wonder it needs a new engine.
MSFS is not a true full screen game. It’s borderless windowed. If you don’t force Vsync globally then Gsync can randomly fail, specially when switching between application windows or using ALT-TAB.

If I set G-Sync to “full screen only”. And disable Vsync in MSFS. I still don’t see any tearing, so it must be working. But I can also set it for “full screen and windowed” as well. Both seem to work equally.
I think establishing a baseline would be useful here. If you empty your community folder and start the game with no add-ons, pick the C172, and go to a little airfield in the middle of nowhere, with Low-End presets, all traffic and multiplayer off, and TLOD as low as it can go, see what FPS you get on the ground. No frame limiting, no vsync at driver or application level. Because that’s a scenario where you should absolutely get as much FPS as your GPU + CPU together can theoretically deliver with MSFS 2020 as-is. If it’s not 100 FPS+ (without frame gen), then something has to be wrong with your system somewhere.
Assuming it’s high enough, then try it with Ultra presets but everything else as above. You should still get a very high frame rate because most of those presets affect the GPU and a 4090 shouldn’t even be breaking a sweat at that point.
Then you can start ramping up TLOD, traffic etc and see how that affects your performance. And finally, start putting add-ons back (ideally one by one) until you see major frame rate drops, and you’ll have an indication of what it is that’s bogging your performance down, and can decide if you’re willing to live without it.
If your FPS is terrible with no add-ons and settings as low as they go, then there’s a bigger issue and I’d personally be tempted to do a complete format reinstall and start again and see if you can repeat the problem. And if you can, then my only thought would be that you have a hardware problem of some kind. And that’s a whole other conversation.
That’s what I’d do in your situation, at any rate.

Thanks. If I have some time I might give it a try. But the truth is this game is due to be retired soon. As far as I can tell my system is fine and works really well with other games.
I get it that if I uninstall everything and do a free flight out in the middle of nowhere I’ll get better performance. But that’s not so exiting.
Reinstalling the game could be an option but again FS2024 is just around the corner.
Sure, and I get that. But if it’s just one add-on or setting that’s breaking your performance, and you identify it and get rid of it, you can enjoy good performance in the game until 2024 comes out. Which, I suspect, won’t be until late this year, probably Q4. That’s pure speculation, I have no inside knowledge, but I have led a lot of big software projects and they are invariably delivered late.
All I know is that I have basically the same hardware spec as you (slightly faster RAM but otherwise identical) and I get much better performance at 4K than you apparently can with similar settings. So it’s not a case of the game performing poorly on the hardware. It has to be settings, add-ons, or some kind of fault specific to your setup.

I have a virtually identical system as well, and get more or less the same results as FlyerOneZero…between about 30 and 80 fps without frame generation. I don’t play around with settings very much. “Select Max Performance” is about it. I run the sim with standard “ultra” settings on a 5120x1440 monitor which is about 7/8ths of 4K.
You have something else going on that’s limiting your sim’s performance.

I haven’t always had this problem, something is amiss for sure.
My problem is, that on my 4080 card, that the GPU memory it on his top, and that make my game stuttering. I have an I9 CPU newest model, highspeed DDR5 128GB. en I run it on the Samsung 990PRO m.2 drive. I use water cooling. So I do not understand, why it use 16GB and why it makes the game slow. I even reinstall the whole OS for this issue. BTW slow, I mean stuttering on default airports. I tried version 11 and 12 beta, but no different. latest drivers. Bios up to date. No bitlocker.
Can you post a screenshot of your developer mode FPS display with the memory usage and performance data?
Here are some tests. An easy situation using the Taxi Training mission included with the game and a complex one using the Asobo 787 at JFK on 31L. AI Traffic and preset weather. The easy scenario results are as expected. Ultra gets 90 FPS and Low End gets 110. I repeated the JFK tests with the Community folder cleaned out. That only made a negligible difference and upped the frame rate by 3 FPS. The difference between Low End and Ultra at JFK is 33 vs 27. So the conclusion here is that add-ons aren’t to blame. The next step I figure will just be to reinstall the game.
Heavy airports/places will be brutal. LA is infamous for that. As you can see it is your mainthread limiting you in those areas, while your GPU is basically just sitting there waiting. Lower LOD and thing like traffic is the main things you can do but even the best system will choke in those areas.

Well I am already lowering settings by selecting Low End and as you can see the game is an only barely playable.
That is LA/NY for most of us. Try different spots in the world to see if you can find out which ones are bad and maybe a pattern?
Try disabling all traffic, including multiplayer and things like cars, and keep everything at your regular settings. Then play around with ONLY the LOD settings, from max to min and synced and unsynced.
It appears the game is unplayable even at its lowest settings. I think I’ve just discovered why FS2020 is being retired. At this point I’ll just wait for 2024 and hope things improve with the new engine.
The pattern is pretty clear. Good performance only in empty areas of the map. Anything complex chokes the CPU. Again, pretty clear why the game is being remade.
