With heavy payware like inibuilds JFK, default Longitude, heavy clouds and FSLTL traffic I definitely get the flickering screen from time to time.  Even with my gysnc monitor.  It's flickering because I'm not able to get the best fps in that demanding scenario.  

I got rid of my "g-sync compatible" Freesync flickering by adjusting the freesync range via to 90-165Hz instead of 48-165Hz. So far I did not observe any tearing below 90FPS nevertheless, so it was an adjustment without any negative consequences in my case. Might try this?

I have a suggestion for any of you guys who have a 4000 series card and you are using a Samsung 4KTV for Display. My setup is 3090 and Samsung 4KTV. I use the TV's Judder reduction setting for frame generation so with the refresh rate set to 25hz and Vsync on, I get a super smooth 50fps out of the 25fps provided by the GPU. If I had a 4000 series I know what that first thing I'd try would be.🤪

Set your refresh rate to 50hz in NCP. Turn judder reduction on the TV up to max using the TV remote control. Turn on FG in game. And see what you get on screen.

By my reckoning if you are flying a scenario that gets you just over 25fps raw with your cpu and gpu maxed out this setup could give you 100fps on screen.

For example you are landing and taxing to gate at inibuild JFK is overcast conditions with tons of AI traffic. Lets say your system can give you ~27fps because its fancy. FG then makes that 54fps. NCP set to 50hz then makes that 50fps and finally the TV's frame generation makes that 100fps on screen.

So you go from 27fps to 100fps.

I dare someone to try it!😏

Here is a sample video that I took, using frame generation off and locking a 30 frames. Seems quite smooth but at the arrival on approach you will see what I call these little skips in the scenery. This is what I'm talking about. Happens also, and it seems more with frame generation turned on. 

 

Look for the 2:33 marker in the video coming into Paine Field. Once the buildings show up you'll see those little tiny skips. And who knows, maybe I'm just being really picky. But I've seen others with less of a system that I have with completely smooth videos. 

 

 

 

I always keep it on, can’t say I’ve seen any bothersome visual issues with FG on.

If you purchase a porsche, do you stay below 3000RPM, or do you go for it? 
 

ON! it’s the greatest thing to happen to flight sim, since flight sim itself.

A couple of things… TV judder reduction or motion smoothing or whatever it’s called does a crude form of frame generation, but it has significant latency. You won’t find this option in game mode on your TV for that reason. It works differently from Nvidia frame generation in that it waits to have two consecutive frames to work with that makes it easy to interpolate a few frames in between. Hence the massive latency. Of course, when you’re watching a movie, you don’t care if there’s several frames of latency, but if you’re gaming, you want what you see n the screen to respond instantly to your inputs.  What’s more, TV frame interpolation or judder reduction on most modern TVs will actually generate 4 frames for each real frame to effectively turn 24FPS film content into 120HZ video - which is why almost all TVs have a 120Hz refresh rate… it’s a common multiple for 24, 30, and 60FPS content. 
 

Nvidia’s FG is very different… it is building a new frame on the fly without having the next frame, it uses only the previous frames and uses AI (machine learning) to construct a new frame. No latency what so ever.

Now you could argue that a flight sim doesn’t really need ultra low latency, and you may find it works fine for you. Just be aware of the trade off you’re making. As always, YMMV.

But at what cost, a 4090 is not cheap, hopefully AMD can give it to us at a better price.

Here is with Frame Gen on and 60 frames instead of my last video on 30, notice on approach there seem to be more little skips 
 

 

Its a game changer , for me at least.

Flying at 50-60 FPS even in the most demanding scenarios ( think Fenix and LAX) and feeling like a real simulator , and not something from 2010 

I find 30 FPS to be jittery, stutter and just old school. P3D and FSX was the same way.

the 4080/4090 aint cheap but until we have CPU's that run 6+ GHZ an all cores " out of the box" , this is the best we have.

A Gsync/Freesync monitor is also essential or else you get screen tears and stuttering. I lock my FPS in NCP around 90-100 FPS , Vsync off in both game and driver , turn full G-SYNC on and it seems to run well.

You do not need the full 4090 setup as long as you do not go VR (where FG is useless) or 4K screen, as even the 4070 provides a good FG experience in MSFS for lower res monitors. I would say up to 1440p you are fine with a 4070(Ti), although I get my 16GB VRAM full using demanding addon sceneries. But full allocation does not necessary mean full usage, no? I never tested the actual usage, just the allocation...

Going back to my last video.. anyone know what could be causing those little skips? Since some of you gave mentioned that they get none of those frame issues.

I remember being at odds with you awhile ago. I simply could not believe that frame generation would make the game perform more smoothly. I thought it was all just over compensation for spending so much on a video card for a marginal improvement. Once I got the card, I intended to use it for VR because it got such high praise. Then I though, ah what the hell, let's see what this frame generation thing is all about...I was blown away. I simply could not and can not believe how well frame generation works. So much so that I actually prefer flying in 2D mode over VR 😂.

Keep frame generation on, it's absolutely game changing amazing.

Hi Bill,

As Virtual-Chris mentioned these are the settings I also use:

Key settings to check:

• Make sure you have G-Sync enabled for both full screen and windowed mode - critical if you ever have a pop-out or other window up
• Enable V-Sync in Nvidia Control Panel (this with Reflex/DX12/FG (below) will cap your FPS at a few below your max refresh rate automatically)
• Turn off any and all frame limiters (Nvidia, game, etc) - not needed 
• Disable V-Sync in game
• Enable DX12, Frame Generation, Reflex Low Latency (they’re all interrelated)
• Try using DLSS for anti-aliasing vs TAA. DLSS can provide sharper details at a distance while TAA can lose these details completely, but DLSS may be slightly less sharp on instruments. 

 

I use the above with my 55 inch Sony X90K @ 100Hz and the sim is as smooth as butter. Are you by any chance using or have used RTSS to cap frames in the past? RTSS does not play well with FG and I found when trying to use it small stutters were introduced. It is not still trying to set fps in the background is it?

I followed all those settings. I do use riva tuner but just to show the frames only. Maybe I'll try to just not have it running at all. Did you notice the jitters towards the landing of my last video? I'm on a 60mgz monitor. The monitor can run 75 megahertz, but I choose to keep it at 60 since my monitor on the side can only run at 60., It's a different brand and not the same monitor. . I don't know if that matters or not.
