The problem is that if I write something like how I perceive 30Hz on monitors, always someone jumps in and «proofs» his point either telling things that are simply not true or, like in this case, using a 30FPS YT video that smoothes out all and everything, notably if you watch it on anything else than 30Hz, you wont be able to reproduce what the real 30Hz situation looks like. Always. 

But it was to rude, yes. I should have made clear from the beginning that it is MY personal perception at 30Hz and thus I do not suggest it. If someone is happy with 30Hz, fine.

Every system is different.

When using 3x 4K tv’s like me I set it up for max framerate 30 and use either FSR  or FG + 2x LS to get 60 fos on all tv’s.

Well, you also did not get the point and this is what I was talking about and made me angry in a way that my response got to harsh. I am and was never talking about FPS, but refresh rate. Thanks to the fact that nVIDIA Control Panel and even MSFS includes settings to go with half-refresh rate for e.g. Vsync, you are perfectly fine with a 30FPS limit WITHOUT lowering the monitor refresh rate to annoying 30Hz, which might be still OK in the sim but terrible on Windows Desktop or when doing other stuff on the rig, e.g. Office work, browsing etc. And there is no need for it, I have my FPS limited to 36 because of the reason you gave here, frame gen makes 72FPS out of it which is exactly HALF of the refresh rate of my monitor (144Hz). There would be NO benefit at all if I now limit my monitor to 72Hz only.

Means: of course limiting the sim to 30FPS makes sense in many ways, but going below 60Hz with the monitor refresh rate is simply not neceassary. 

Have a new monitor 32 samsung G5 165hz running on a RTX 3080. Had another larger monitor running at 165hz but did not have this issue. The other monitor had bad pixels and returned. The swimming textures are around the boxes in the PD on the mD11. Is this a refresh rate issue timing issue, a texture quality issue. Its not just the MD11 its on all aircraft where horizontal lines are used like out line PD or engine read outs. I have tried dropping to 60hz in nvidia CP and also tried to leave CP alone and just tweak in MSFS settings. Is there a way to stop it? Thanks

I agree with you : I set it to 30 and double it . The tv’s are running at 60 hertz 

What I meant was you better can set max framerate to 30 (and double it) than setting it to 60 and it is almost not reachable for the system ( so choppy)…

Exactly! My frames never budge from 30FPS. If I run 60 with 1/2 refresh I get additional flickers as frames drop below 60 into the 50s and 40s, depending on the area!  Flight siming since 1985, been around the block a few times. also keep in mind monitors like mine that are ten years old don't have G-Sync or any other advanced frame smoothing  features.

Maybe on your system with newer monitor(s), you can get away with that, but on older TVs, it doesn't work nowhere near as well as the new monitors. Aside from that no one was talking about outside of Flight simulation!

Aside from the fact that Vsync doesn't work well in XP12!!! Since I run both base platforms on a regular basis, switching back and forth every run isn't an option I'd like to explore!

Your statement and I quote "You can instantly see the flickering then, and it provides zero benefit over e.g. 60Hz and using the half refresh rate approach."  That is an incorrect statement, based on all my testing and the fact that one cannot see any instant flickers in my video. and BTW, I run ULTRA in 2024 with seven monitors!

I also don't introduce fake frames into my flight simulation experience.

It all comes down to what you see and satisfies you.

You are around for a very long time 😎

You still dont get it, do you? It is IMPOSSIBLE to show on a compressed 30FPS Youtube video what I was talking about, because a) YT smoothes out everything and b) depending on the playback device, you might end up having the 30FPS video on a 60 or 144 or even higher Hz monitor. The only way we could properly judge what you are claiming is by sitting in front of your very setup and checking it with our own eyes. If you do not see what I call "flickering" (might be the wrong wording, but english is not my native language) in the YT video it simply does NOT mean there is none in reality, because it could simply be eliminated by the compression and low FPS/Hz rate of a YT video. It proofs nothing.

But yes, I now understood that you have rather old monitors and it might be that because of this, the half-refresh rate approach doesnt provide equally good results. Understood. And you tested both and for your very specific case, it is the best solution. Fine. All I was saying that I would not do it, because for 90% it is NOT the best solution. 

Besides that, if you say you do not talk about "outside flight simulation". Yes we do, I expliciteyl said in my post that switching refresh rates back and forth is cumbersome and this is also a reason why I would not suggest lowering the monitor down to 30Hz. 99% of the simming people do not have a homecockpit like yours and most probably use their main monitor for tons of other things than flight simulation. And no, I would never, ever accept doing Office work on a 30Hz monitor anymore. 

And because of people accusing me from being to bold/harsh/unfriendly I am not commenting your statement about fake frames, because it is the next not very well thought statement... just a small teaser: your frames are digitally rendered images. There is nothing like "real" or "fake", there are just different algorithms providing you with the one or the other, generated image. I bet you use DLAA ot TAA as antialiasing, no? So much for your native, "real" image, it is massively upscaled and downscaled again if you use TAA, nothing "real" and for sure not a lot less "fake" than what you call "fake". Think about it...

I guess all the videos I recorded and watched for over "TEN YEARS"  before placing on youtube were just my imagination of being smooth and all had instant flickers as you state? That means I'm looking at three 75" screens that are flickering while I fly, Nope not correct! I can have actual people that have been in the flight deck that can attest to the fact I don't suffer from instant stutters.

No matter how much youtube reworks your video, if you have stutters and flickers they will be there after youtube gets done with its programming!!! I can show numerous youtube videos here that show flickers.

One more note about youtube and stutters:  and don't take my word for it, do a google search yourself!

Here is a test, record a video full of flickers and upload to youtube, then playback. Watch all the flickers still in your video!

YouTube Video Playback Issues

YouTube does not have a built-in feature specifically designed to remove flickers and stutters from videos.

I almost forgot about this video when testing MS2020, if you're correct about youtube fixing stutters...

Why didn't Youtube smooth everything out from the video below? Because youtube doesn't have the ability to separate the live presentation from the three video screens! Not sure why you are unable to understand this simple scenario, youtube is not going to adjust/smooth out those monitors at all.

The original poster has old monitors/TV's like I do, matter of fact from the same company Samsung. My sets are ten years old, not sure how dated his sets from Samsung are... but if possible based on other hardware, he may be better off locked at 30Hz/30fps and bumping up his resolution from 1080p to 2k running ultra or go 4K and maybe lower some settings. But that depends on his hardware.

Ok, now you are suddenly talking about stutters, while the disussion was about flickers due to low refresh rate. You know what, you obviousuy dont get the point, fair enough if your setup works for you it final y also doesnt really matter. Go on thinking that a video taken from a camera with whatever FPS and refreshrate and playback of this video on whatever device has no impact on whether or not you can actually see what I mean. I then simply wonder why people not only use 30Hz all the time? If no one can see the difference, no need for more Hz, no? 

Maybe AI can explain my point better: 

YouTube videos can show 30Hz monitor flickering, but usually only if the recording device's framerate, shutter speed, and the monitor's refresh rate are perfectly matched to avoid interference. Otherwise, the flicker may not appear accurately, or may appear differently due to inconsistent frame rates between the camera and display. 

Key points on capturing 30Hz flicker:

Camera Settings: Matching the camera’s shutter speed (e.g.,  or ) to the monitor's 30Hz frequency is essential to capture the effect accurately.

Aliasing/Beat Frequency: If not perfectly matched, the camera may introduce a "beating" or shifting flicker pattern that does not accurately represent the real-life behavior of the 30Hz screen.

Limitations: Because most YouTube content is viewed on 60Hz or higher displays, a 30Hz flicker may be masked or appear as a strobe-like effect rather than a smooth, constant dimming. 

But hey, of course your capturing setup is fulfilling above requirements, that is why your YT videos would show the flickering if there is some, no? Ridiculous discussion...

Whatever you want to call them, youtube won't fix them!!! As seen by ones own eyes in the videos provided!

I personally started using https://mac.eltima.com/free-universal-remote-app-for-iphone/ to quickly toggle monitor settings and inputs without messing with the physical buttons every time.

Since you noticed it specifically on horizontal lines like PD outlines and engine readouts, the monitor is likely struggling with the pixel response time when dark textures move against a slightly lighter background.

Instead of just changing the refresh rate in Windows, you should look into the monitor's own internal settings. Try going into the monitor OSD menu and finding the response time setting. If it is set to fastest or MBp, it can actually cause inverse ghosting or that swimming effect. Setting it to standard or fast usually helps balance things out.  

Another thing that often works for the G5 is checking the DisplayPort version in the monitor settings. If it is set to 1.4, try switching it to 1.2 directly in the monitor menu. Some users have found that the 1.4 setting causes weird sync issues and artifacts on this specific model even if the GPU supports it.

If you have FreeSync or G-Sync enabled, try turning it off completely both in the monitor menu and the Nvidia control panel. Sometimes the brightness flickering and texture swimming on these panels are a direct result of the adaptive sync struggling with the frame rate fluctuations in MSFS.

Lastly, check if there is a firmware update for your specific G5 model on the Samsung support site. They have released updates specifically to address flickering and display stability for the Odyssey line which might fix how the panel handles those fine horizontal lines in the cockpit.
