My monitor have LFC and it doesn't help at 30 fps, I get tearing without V-Sync.

Is it working properly then?

Yes, but probably not all way down to 30 fps, at 40 it's fine.

You know why right? To avoid tearing if you get high FPS and go above your monitors refresh rate. That is NEVER going to happen with a 144 HZ screen and MSFS, unless you're running bare minimum settings over the desert. 

So, if you are running G-Sync in MSFS, DISABLE V-SYNC. If you enable V-sync in game, it will stop G-Sync working, and if you enable V-Sync in the nvidia control panel, it will do absolutely nothing unless you're above 144 fps (on a 144HZ monitor). Either way, both options aren't needed for MSFS. 

I'm not sure this is correct.  This guide explains why V-Sync should be on (in the NVCP, turned off in game)) with G-Sync for frame timing purposes.  G-Sync varies the refresh rate, but V-Sync is required for the variance in the time it takes to render each frame.

The article also explains Latency should be set to on, if the fps is never likely to go above your refresh rate.

The only solution I found to frame time spikes in msfs was to either use the games V-sync option (which disables g-sync), or, use RTSS to limit the frames to what my computer can consistently achieve. The latter worked the best and the frame time is consistent 90% of the time.

So you think that article is incorrect?

At what point did I say that? No I don’t, I don’t think it’s right or wrong. I’m just expressing how I managed to get MSFs smooth with a smooth frametime. Following the above article only, wouldn’t have given me the result I achieved.

The article states that G-Sync plus V-sync in NVCP will give smooth fps, but you think different - what do you think the flaw is in that article?  I would have thought V-Sync would ensure each frame is timed correctly?

It isn’t just me that thinks it’s a flaw. Go do some research for yourself, and read over the MSFS forums. 
Do some real life testing and come to your own conclusions. I’ve come to mine:-

V-sync enabled in nvidia control panel whilst using g-sync does not smooth the frame time in MSFS.
V-sync enabled in msfs does smooth the frame time, if you can achieve the fps set, but disables g-sync. 
vsync disabled  in both msfs and nvidia control panel, but using RTSS to limit the frames to ones that you can achieve ensures g-sync still works whilst smoothing the frame time out. 
 

this is what I found out, in msfs, using real world testing.

Very interesting - you would think V-Sync plus G-Sync in the NVCP would smooth out fps/frametime 100 percent, but on your system a different solution is giving better results!  I'll have to give it a go.

Is it possible by limiting your framerate, you are just reducing the opportunities for the frametime to be out?  You mention you mentioned a figure of 90% smoothed.  I wonder why Your frametime is not smoothed using V-Sync in NVCP.

Graphics settings are a dark art!

What a response! Thank you! So, from what Ive understand is that Vsync should be OFF / OFF and then you should use something called RTSS. Im not familiar with that. What is it? Could I live without it? Right now, after turning Vsync off in both game and NCP, relying to my Gsync (compat) screen...I'm back to only Maximise Power in NCP, and the using vsync in game and 30fps. It feels really, really smooth but my GPU seem to work A LOT. It still is not very smooth from time to time... Do I need this RTSS for it to be perfect? Any other suggestions?

Thanks once again! 

It is exactly as Ian says.

I managed to buy a decent 28 inch 4k screen, but it only does the cheaper 'g-sync compatible' thing, which means in my case, anything below 43 fps and it won't work.

With only 30 fps vsync locked, the motion is a little bit jerky on a big screen when going fast or looking sideways at low level. 

I can't use vsync at 60, as the GPU gets really hot and noisy at my graphics settings, and the 3080Ti can't quite hold it anyway (makes about 57 fps). 

So, I use RTSS set at 45 fps frame limit, and then the GPU is fast enough to hold that (in 99% of cases), and it doesn't get too hot or too noisy on the fan, plus of course, gsync also kicks in on the monitor.

I was hoping my gsync would work at lower fps than this, but even at gsync 'ultimate' setting, it seems it doesn't work very well below 43 fps.
I will say, the difference between this 43-45 fps and 30 fps is very noticeable, or at least it is for me on a large screen.

You have a G-sync monitor and a Nvidia gfx card, so WHY would you even bother with vsync?!

I had a flickering screen and discovered it was G-SYNC related flickering.  The flickering has stopped when V-SYNC in game was used.

Did NCP have this feature too? I can only find Max framerate, and thats not really the same right? Withouth trying this, best "so far" seems to be Vsync ON in sim and 30. In NCP I have only maxed performance.

Flickering On a G-a sync screen means you probably only had a g-sync compatible screen. A proper hardware based g-sync screen doesn’t flicker all the way down to 1hz. At all, ever. 
 

Let’s say you have a 144Hz VA gaming monitor with brightness flickering in some of your games.

There are two main reasons you get brightness flickering: LFC and frequent FPS fluctuation.

If your gaming monitor has a variable refresh rate range of 48-144Hz, it will trigger LFC(Low Framerate Compensation) once your FPS (Frames Per Second) hits 47FPS or lessif you have an AMD graphics card.

Now, LFC multiplies your framerate in order to eliminate tearing even when your FPS dips below the monitor’s VRR range. For instance, at 47FPS, it gets tripled to 141Hz.

So, let’s say one second you have 48FPS, and therefore, 48Hz, and then, the next second, your FPS drops to 47FPS, and your refresh rate spikes up to 141Hz.

Because your monitor is brighter at higher refresh rates, brightness oscillates.

If your FPS is constantly around 48FPS, LFC rapidly goes on and off — thus causing brightness flickering.

 

The reason your flickering stoped when you used v-sync is because your screen will always be at its highest hz, therefore at its maximum brightness. LG TV’s with g-sync also suffer from this. 
This is why, if you’re gonna purchase g-sync, do it properly and get a hardware based monitor 🙂

I have now tried to turn Vsync off in game as well as in NCP. I then wrote 30 fps as limit in NCP. Too be honest; its not as smooth at all as it was with Vsync in game (off in NCP) and 30 fps in game. Not sure if its NCP's limiter thats the problem. Maybe Rivas solution is the way to go...? I was a bit surprised that all butter smooth feeling (exept for a stutter here and there), suddenly was gone.. cause when I get this right, 30fps will feel buttery too right? =P
