Using driver 5.36.23 + MSFS 1.33.8.0 still Vsync does not work.
No difference between 33% -50%-100% .
If I change weather I can see the framerate changing so Vsync does not work.
Tried with NVCP settings to : Vsync On / Application Controlled. Adaptive .
No difference… The framerate is above the refreshrate so Vsync does not work.
Tested it on 2 different MSFS pc’s…
I’ve also go this issue (I guess everybody does at it appears to be either MSFS or NVIDIA). Would be great to see an update for it in SU13
VSYNC on in NVidia Control Panel and off in game, with frame generation enabled locks the sim to half my monitor’s refresh rate with frame gen filling the other half. This is with 536.09
Are you using a VRR capable monitor? (e.g. GSYNC)
If not do you not see this issue in the FPS display in Dev Mode? (FPS jumping between 2 distinct levels).
I have a G-SYNC monitor yes
Thanks for clarifying. I point out in my first post that this issue only occurs with fixed rate monitors but I’ll change the title to make this more obvious.
This is exactly what I get when I turn FG on. However in my case my main thread times goes from 23-25m up to around 50 ms. God alone knows why turning FG on kills my main thread but thats what happens. I’ve tried every combination I can think of in NV Control Panel and Windows to no avail.
FG is great - but its not yet implemented well enough for me to enjoy it in MSFS.
What happens to your main thread when you do that? It kills mine and I get terribly jerky movement. That said I’m on 536.23…maybe I’ll try your 536.09 and see if it makes any difference…
Hello everyone, I found this thread thanks to avsim, and, unfortunately, I’m one of yours. I own a PG348Q on 4090, lately I’ve found that, using trackir, the sim is super smooth by disabling gsync, putting vsync on in ncp with fps limited to 60 (refresh 60hz). In this way I also have the perfect trackir response, but, as already mentioned here, this situation means that after a few minutes, no matter where I am, no matter what addon, the sim starts jerky, I’m not stuttering, I’m really slow down and it’s very noticeable in flight, because if you look at the ground below it seems to go in slow motion, and I suspect it goes as if it were 30fps. As mentioned by others, I solve the problem by clicking on the second monitor and returning to the sim monitor, otherwise the ALT+ENTER x2 sequence also works, i.e., reduce to window, and then put it back to full screen. The funny thing is that, during the slowdown, if I move in the cockpit with the trackir, the movement is fluid, as if it hadn’t lost any fps. An absurd thing that suggests that there is something wrong between framegeneration, vsync and maybe more. It goes without saying that I have done all kinds of tests, including changing drivers, even putting very old versions, touching a lot of settings in ncp, but nothing at all, the problem is also easily replicable and I think there is no one who does not suffer from it , only that, to see if the problem is present, it should be tried in a well-defined situation, i.e., 60hz+60fps and vsync on in ncp (and gsync off). I would have hoped to find a solution but now I have raised the white flag and with considerable annoyance, because this thing is not good. Already it would have been enough for me to understand what really causes that problem, even without an immediate solution, but at least understand what triggers this big problem. The fact is that I’m forced to go back to gsync, unless, very often, I click on the second monitor to return to regular fluidity, this thing is a bit funny though.
Yeah its a mess - make sure you vote for this thead to raise more awareness. They’ve marked it as “bug logged” but that doesn’t mean they’re going to do anything about it
This is unlikely to fix the issue described in this topic for most, but posting since it could help some. Make sure you don’t have any frame limiter applied with a lower FPS than your native refresh rate while using FG. It will cause extreme stuttering similar to what is described here.
For users with GSYNC capable monitors it is rather common to limit the frames to just below the native refresh rate to ensure the VRR method always is enabled. Until I realized I had it limited globally in RTSS to 141, frame generation was completely unusable in MSFS. Removing the limiter instantly fixed all stuttering.
I have been facing the same issue - FG with VSync ON NVCP - this worked flawlessly when FG came out and then broke hopelessly not long after.
Low Lag Vsync seems to work with current MSFS version.
I have no idea what that guy is talking about - His accent is impossible for me to understand.
Can you explain what this low lag VSync is all about? Does it bring VSync back to MSFS with FG on?
Now you should have MSFS frame rate 30 fps and final frame rate 60 fps. Without this frame cap in RTSS, MSFS frame rate is not half of monitor refresh rate and that creates stuttering when FG is enabled.
For the video you can enable English subtitles.
Hi,
I had the same problem before and tried the method described in the video and can say that it was successful for me. Now i finally can use FG again without having to buy a new monitor 
I tried Framegen for RTX3000 cards, didn’t like it so much and reverted to DX11 without Framegen…
Well, to revert, i went back from “Control Panel VSYNC on + SIM VSYNC off” to the previous “Control Panel VSYNC OFF + SIM VSYNC on” - but it doesn’t work.
I still get tearing even though VSYNC worked before and the developers panel says “Tearing Forbidden”.
I tried DDU and reinstalling the Drivers, but it didnt help
any ideas?
I recently purchased the 4070S and to my disappointment, I noticed that DLSS3 doesn’t work as claimed in MSFS. What makes this even more frustrating is that this simulator was touted as a flagship product for DLSS3. As easily discernible from this thread, I’m not alone in encountering this issue. The only silver lining is that the problem has been acknowledged with a ‘bug-logged’ tag.
While there are certainly other individual issues with MSFS that haven’t progressed on the fix list, I can’t help but wonder how such a crucial matter remains unaddressed. Please don’t let this issue hang on like “blurry instruments while using DLSS” which to this is date is not fixed.
EDIT: Thanks to @LaudableCoder29 for the video, glorious smoothness BD
Regarding the video @LaudableCoder29 posted => Just a quick update on something I just found out. It appears that the default RTSS-sync is set to ‘ASYNC’ in ‘SETUP’. Well, as it turns out, there are a couple of other options as well (notably NVIDIA REFLEX). I found out that by that simply choosing the proper setting ie. NVIDIA REFLEX, most of the lag just vanishes which was present in the default async-mode. I think were quite close to what msfs would feel like if FG were properly working on fixed-sync monitors by using this mode.
Please post your experiences, so we can verify that this isn’t a fluke.
any news on that?
Hello,
I have 120Hz monitor with G-sync. Whats should be my settings?
G-Sync on?
RTSS lmit frames to 119?
NVCP Vsync ON?
MSFS Vsync OFF?
Thanks
