My sim can ble completely fine one day, then utlra stuttery mess the next day. 

What changed? NOTHING. 

Even at the same airports! I don't understand... 

I personally believe this is due to the streaming scenery. I too noticed that.

PS the south bay area of LA south of LAX (Torrance to be precise) is a stutter fest, and has some random water bodies thrown in that are not there in real life. (There is one showing near Torrance Boulevard near the intersection with PCH).

I think it's got something to do with the scenery as well.

The strange thing is that it can be 100% smooth one day, and then stuttery and unusable the next day.. at the same place, looking in the same direction. 

It probably has something to do with the rolling cache.

Yep, and still i have some special areas i can't go to because of extreme stuttering for no obvious reason.

mine is off. still issues

Couple of other suggestions in case they help.

Under Windows 10 Game Mode settings:

- Try enabling Game Mode if it was disabled, but disable the Game Bar

- In the Captures sub-menu, disable background recording and recorded audio

 

In the Windows GPU settings (type GPU in the search bar):

- Pick Flight Simulator from the Windows Store Apps. Add it and set the preference for it to High Performance

 

In the Windows 10 display settings (assuming you're running the latest graphic drivers and your GPU supports it)

- Enable hardware enabled GPU scheduling in the Graphics Settings menu

 

If the above don't show improvements, you can also try disabling fullscreen optimization on the Flight Simulator exe and override High DPI scaling behavior [NOTE: if/when DX12 is released, these settings should be reverted back]

In general the core constant FPS is good. Very good taking into consideration its a flight sim. The problem is the optimization that lowers the FPS to single digit for a second. And its not related to heavy loaded areas.

I have also noticed that coherentGPdraw causes stuttering. I believe this is linked to glass cockpits. It is butter with the C152.

If you look at the console, once those stutters starting there is some errors named: "overwrite taxi name at LKMR"(ICAO changes as airports loading). 

I got about 10 of these with different ICAO. 

Any idea what is it ?

Hmmm... it colud be.

Is it any topic about this in bug section on MSFS Forum? I can vote it.

I noticed very small stutter only after landing (not the same airfiled) on airstrip/runway. If i go to taxiway the stutter gone. Something is broken with runway (code or something else).

 

Where is this?  Enable hardware enabled GPU scheduling in the Graphics Settings menu

Type in the Windows search "graphics settings". If you got windows 10 2004 update.

For nVidia cards, you will only find "Enable hardware enabled GPU" with a GTX10x0 generation or newer (RTX) cards. It can't be done on the GTX 9x0 and earlier cards. No idea about AMD cards.

Got it

Just to confuse things further. I am seeing right before stuttering or crashing there is an Event Log Warning with an ID of 157 - Disk # has been surprised removed. This occurs right before the Event Log Error for FlightSimulator.exe. The Disk # is higher than the physical number of disks in my system. I went to Device Manager and selected View | Show Hidden Devices and then several VHD's (Virtual Hard Drives) showed up under Disk Drives. MS Store apps are contained in VHD files. I cannot tell you if this is an issue, just something I noticed. It would be interesting to see if anyone else is noticing this 157 warning right before a crash or stuttering.

Yes this is for sure ! They did a terrible job with these. They tried to solve it with the refresh rate option but its not it. As a matter of fact the 'High' is better then the 'low' for me.

Not sure if you have it or not, but try the Carenado Mooney plane. It seems to not use CoherentGTdraw. However, it is heavily CPU bound, so it is constantly limited by mainthread.
