What kind of storage media are you running from?

Like the ground is skipping? Sounds like vsync issues

Indeed I also think vsync issues.

I also tried to fix this (using 60HZ Sony TV)
Tried eveything still happening

just run everything on ultra and stutters may reduce ! Yes the opposite of what you think however on my laptop ... I was getting a somewhat stuttery 60FPS on default very high but when going to default ULTRA my FR may have gone to 30-45 but it is way smoother!!! try it (1080 asus laptop)

This happens when you push the load to the gpu and take it away from the cpu.

Only way I ever eliminated that was with g-sync. I know some people in here run 30hz and go on about it, but it’s too low for me.

Looks like the next clash is going to be 4K vs. lower res ...

And as usual the answer will be: try for yourself and choose what suits you best.

If possible, without insulting those who don't share your judgement.

Where are my popcorns?

Changed output to 30HZ and Vsync on in FS and on 60 gives me stable 30FPS.
Also much smoother..(very happy)
I will stick with this for now.

Thanks for all the help. Yes its like the ground is skipping. Use external vsync or FS? Also running from an SSD Sony 750 drive. Also if running Steam how do you get Riva to recognize MSFS there is no EXE?

If you’re running a 3090 on anything less than 4K, you’re going to Make the sim cpu limited. Which in turn will induce stutters. Not what you want. I’ll not go in to more details, as a search of this forum will explain all, but, don’t post advice like this, because it just doesn’t help. 

I'm a gaming programmer, not crazy... There are better ways to adjust than forcing the GPU to fill up, the issue is your other settings that are inducing this together. Do not assume that you have your settings correct and that DX 11 has an inherent problem with thread priority between the CPU/GPU just because that is what you see in your situation, that is not how it was intended to work when your settings are correct (At any resolution). This may be the quick and easy fix and be a fine and dandy workaround, but it usually means you have not got the optimal settings. The common cause is having game mode enabled in Windows 10, but it totally depends on all NVIDIA settings combined to whether or not you get this "GPU flood" required issue to reduce stutters or induce max performance. This issue is not specific to MSFS. My point was not focusing on performance though, I was talking about for visuals. Also, do not assume that you can universally apply your experience to everyone elses hardware or software settings, there are too many variables. It will vary in any given situation.

Likewise.

I am not assuming, I'm basing it on experience working on games. People often gravitate towards the idea that it's a defect in the game or that you have to change GPU/CPU load to balance it, but it's actually hiding the issue by doing this, not resolving it. FS 2020 could be different, but the only game I ever really saw this on were alpha state games like Star Citizen. Even when I worked in Unity and Unreal engine, saw this issue come up many times over the years in my own setup, but it usually had nothing to do with DirectX or the game, always NVIDIA settings or weird hardware pause in Windows.

I wasn’t on about that. I was on about the bit where you basically said don’t use 4K....

How often do you see the stutters? Is it once a second, or is it continiously? If it's once a second or so, it could be the TV settings not being able to handle the input correctly. 

Is your Windows up to date? I know the 1903 version had issues with stutters.

Another thing you can try is to force the TV to 60 Hz. I have a Samsung 4K TV, and it was automatically set to 50Hz when connected. I had to manually change it to 60 Hz.

1. Type Advanced Display in the search bar in Windows. This should open Advanced Display Settings.

2. Select the display you want to change. Choose your Sony TV.

3. Click Display Adapter Properties at the bottom of the menu

4. Select the Monitor tab. Select Refresh Rate from the menu.

This should help if it wasn't set correctly.

You should also check in the Nvidia Control Panel -> Manage 3D Settings -> Global Settings -> Power Management Mode ->  set to Prefer Maximum Performance
