No issue that I can report on my side with this 576.80 and MSFS2024 SU3 and this PC configuration.

I have the 5080 and my issue was my monitor would constantly switch between displayports and go black when I enabled gsync. The only workaround was creating a custom resolution. Todayās driver update finally resolved the issue.

ah ok thanks.
Iām using only hdmi, as DP has been completely unusable in the 57X.xx drivers for me. System usually doesnāt even boot, just sits at a black screen without even reaching POST. If I unplug monitors, it boots, but then random black screen during gaming.
HDMI seems fine though.
Running this on a GTX 3070, and an ASUS GSYNCāed monitor. No issues. Actually, I donāt notice any difference from the previous driver version. In TAA mode - I am not using any frame generation stuff and limit my FPS to 40. Very smooth, predictable result with no VRAM warnings on my 8GB GPU. Oh, BTW, I am also running at 1920x1080 and 120 vertical refresh rate.

Just tested new driver. Seems fine. Not really any difference from the previous one.
Iām too scared to try switching back to DP or try gsync again.
So currently running full res 7680x2160 again, but dlss balanced mode now (with dlss4, this actually still looks pretty good, especially with such a high starting resolution).
Gsync off, vsync off, low latency on. Gpu scaling. Frame gen on. Graphics settings all max (but turned shadows and cubemap back to max in sim values, rather than pushing further in the config file). Tlod and olod both at 200, but can push these higher in most situations (just not the busy hubs). Traffic all on 10-20, live traffic on, multiplayer off.
Without gsync you do get a very subtle, i guess youād can it, ājudderā or āframe persistenceā maybeā¦ but the frame gen really is helping smooth out the āstuttersā i was getting with gsync on.

Iām a broken record on the subject of GSync. Not long after its release in 2013, I learned the hard way (after spending $800 on a GSync monitor) that itās not GSync that smooths out the image, itās the refresh rate of the monitor. At one point, I had 3 27 inch monitors running. All 3 were capable of 144 Hz refresh rate. Only 1 was GSync capable. Operating at 144 Hz, it turns out, is all I needed to have an insanely butter smooth image during game play. I literary did a side-by-side comparison and there was absolutely NO visual difference between the $400 144 Hz non-GSync monitors and the $800 144 Hz GSync monitor.
With 12 years in the field, nothing has changed. GSync continues to generate more problems than it solves. It has never worked correctly and certainly not as advertised by nVidiaās marketing gurus. GSync and ALL frame sync technology is garbage, in my opinion. I think itās long past time for us to kick it to the curb and simply buy high refresh rate monitors. With the monitor refreshing at 100 times per second or faster, it is simply impossible for the human eye to detect any tearing that may be occurring.
Thanks for taking the time to respond and with the screenshots. 
Well I donāt know what settings are incorrect. I donāt have any issues with other programs with my current settings.
Iāve tried just about everything I can think of, adjusting the monitors settings, HDR calibration, tweaking some of the brightness and contract options in the nvidia control panel etcā¦
Reset everything to default and tried again and again but still no joy. Borrowed a friends monitor for a weekend to try, same issues. The only thing Iāve found so far that gives me a satisfactory image quality are the Nvidia filters.
First 576.80 flight in 2020, no complaints from the FBW A320NX or the pilot. Cheers!

I had the same issues with my Samsung monitor switching back to DP when gsync was enabled but this driver has fixed the issue.

Sadly not fixed for me. Dp still unusable.
Have you tried creating a custom resolution via nvidia control panel?
Yeah, itās not available due to display screen compression being always on for my monitor.
No big deal though. Hdmi works fine.

Interesting. I just turned off my GSync and cranked the vertical refresh rate up to max- 165.
Will try this config. for a few days and see how this works on my system.
I donāt agree. I own a G-sync full range monitor and it works as expected since I purchased it some years ago. However there are some requisites and conditions people tends to forget:
- Full range monitors provide the true fluid experience but they are expensive. Cheaper ones are not full range because they donāt include the Nvidia chip and therefore they are only G-sync compatible. This means, for instance, they will only work above 30/48/60Hz depending on model and that means you need 30/48/60 fps in game as well to see G-sync compatibility working. Below those fps values there will be no G-sync at all. This is not a G-sync problem, but a monitor problem. Supported monitors list is below. Anything not listed here or with min variable frequency above 1 Hz (the ācompatibleā ones) can lead to problems:
-
Exclusive full screen applications barely fail. However borderless windowed applications (like MSFS or FS2024) fail as soon as rendering focus is not in those applications. This is not a G-sync issue but how Windows and G-sync are meant to work. As soon as you click outside game or it loses focus after ALT-Tab, Windows desktop or other aplications take priority instead and therefore G-sync will match 120Hz or wathever your monitor refresh value is set in Windows or that other aplication. So, it wonāt match the fps in game. In that situation the game will appear to stutter but this is not a G-sync error. G-sync is still working to render desktop or the application that has the focus. The rest of things wonāt be fluid.
-
As far as I have seen main current sources of stuttering/microfreezes are game, frame generation and HAGS, but not G-sync. If you disable HAGS and use AMD FSR3 frame gen instead of Nvidiaās frame gen (as AMD does not need HAGS) you will remove most of the stuttering in big cities. Nvidia DLSS is simply broken in FS2024. SU3 is expected to fix the ones at airports according to latest beta build release notes. Anyway, despite that situation, even in the case of heavy fluctuations in fps G-sync will still match monitor refresh with it, no matter how low it is, so will keep working well.
Cheers
Working fine for me on SU3 Beta, with a 5080.
No difference I could see to the previous version.
Iāve managed to get my system booting with 3 screens now. Main monitor hdmi, but on the lower port. 2 small monitors via displayport.
No more black screen at boot. Chatgpt suggested that some cards have issues initialising hdmi port 1, leading to no post.
So now at least I donāt need to use the startech usb-hdmi adapter.
Iāll give gsync one more go.
But i think you might be right, some monitors just donāt implement it well.
Mine is technically a freesync monitor, so it has a range of 48-120hz for gsync. (Or 96 to 240hz if Iām in 240hz mode, but that does limit resolution to 5120x1440).
Most games do play fine with gsync, but on my system, flight sim doesnāt seem to.
Still on flight sim 2020 here by the way.
Ok, so Iāll need to do more testing, but, in flight sim 2020 at leastā¦gsync does seem to be working s bit better when i turn low latency off and vsync off from nvcp (these are set to ultra and on for most cases when youāre using gsync).
I still feel like thereās more stutter than fixed refreshā¦ but Iāll keep playing around
On my 4th 576.80, FBW A32NX flight in 2020 (and my first after the DLSS update); very smooth, nothing glitchy that wasnāt so before. FPS as expected given add-on scenery DLCs.
Would love to give this a try, but Iām still on flight sim 2020.
From what I can gather, thereās no FSR3 frame gen in this version of the sim, only FSR2 without amdās frame gen.
Thereās a mod which replaces dlss with amd fsr frame gen, but this still requires HAGS to be turned on apparently.
After work later, Iām going to test hags off with no frame gen and also with lossless scaling again as an alternative. With lossless scaling you can also have gsycn off for flight sim in the nvcp, but turn gsnc ON in lossless scaling if you want to try with/without gsync more easily (and from what Iāve read, if youāre using lossless scaling, this helps avoid conflicts when both the game and lossless scaling are both doing their own implementation of gsync? not sure how true that is or how this all works, but Iāll test later.
Appreciate the info about HAGS, hopefully this will pay off.
@Wdseith You mentioned testing three monitors but didnāt specify the exact models. Could you clarify which ones they were?
If possible, also include their production or purchase dates, since firmware or panel revisions can make a big difference.
I donāt agree with you - tearing can still happen at 100Hz or higher, especially if VRR isnāt active.
Most G-Sync or FreeSync monitors only support VRR starting from 48Hz, so if your FPS drops below that, VRR stops working, and you get tearing or stutter - exactly what VRR is meant to prevent.
Also, high refresh rate and HDR mean nothing if the actual panel (matrix) used in the monitor has slow response times or weak VRR implementation.
Bottom line: Itās not just about 144Hz on the box. What really matters is the type of matrix used and whether VRR works across the full FPS range.
Ideally, VRR should kick in as low as 20Hz, so even in heavy scenes you stay smooth and tear-free.
