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

 

Hope these help

How did I not know of these? I've only used Nvidia Control Panel and the default Windows Display Settings.

If you have the Steam version, and wish to give this a try, in the same place in settings:

- Set to "Desktop app", click "Browse". Navigate to your Steam client folder, subfolder "steamapps\common\MicrosoftFlightSimulator" and select "FlightSimulator.exe". Click "Options" and set accordingly.

(Not sure where the default Steam Client installation folder is, as I intentionally installed it on my NvME drive G:).

Did several tests comparing photogammetry on and off. While it improves things some (maybe half as bad?), it's not a cure for me. Not even close. LA, Miami and to a lesser extent, San Francisco are still giving me some stutters.. LA still complete freezes. The work continues.... 

Are you running a configuration that lets your system work no more than it has to to produce a smooth 30 frames per second, i.e. using an efficient limiter?  This, I believe, is critically useful.  Vsync to 30Hz capable screen works best for me, then RTSS after that.

Yes. Frame rates limited to 30 Hz. I'm pretty convinced this is a bug/design flaw in the simulator. When these pauses occur, nothing on my system or network appears to be being taxed.

Early on after the initial install I was getting those in flying from KSBA to KPSP over LA in the TBM, "those" meaning 1-2 second hangs when the main thread (goes to that last core/LP) was nowhere near 100% and neither was GPU utilization, and yet frame rate dropped below 30 and with it loss of stutter-free animation.  Enabling hyperthreading completely solved this for me.  This may be a red herring because now even w/ HT off now I haven't had these 'long frames' happen for a very long time.  I think there may still be a small advantage w/ HT enabled but not sure.

Is it safe to assume you have Render Scaling set to 100 or less?  This is about the only thing that will just freeze the sim for me.  I can go 110-120 sometimes but there is no appreciable improvement in visuals so it stays at 100.

I've always assumed these dips below 30fps had something to do w/ the server being overloaded not my network bandwidth which is good.

Also, deleting and rebuilding the rolling cache may help--I've done this w/ each patch.

Update: Dropped LOD from 200 to 100 (I've never not been able to use 200 prior to 1.10.8.0). This made significant improvement. More than turning off photogrammetry. Not perfect. Maybe 75% improvement. Tried turning off Live Traffic to no traffic. No difference. So that is not a contributing factor.

ADDITION: Tried the  Cmd line sysdm.cpl,3 background processes priority setting.... No difference.

I fly 320 in la area too. I also noticed performance decrease after the last update. What helped me was  to not only turn off online traffic but also turn off, multiplayer and online ai off. Along with turning off gi and ai planes in graphic settings in ms2020. These brought my FTP back to 50+ i nla area with a320.

Traffic made no difference for me. Render scaling (which I'm running at 80%) also made no difference.

I also think it is a good idea to delete the rolling cache periodically then rebuild it. I just spent an hour trying to figure out why I was seeing a degradation in performance from a few days ago. What I did find is that some how my rolling cache location had changed to the default location so I deleted it then moved it to the fast NVME drive MSFS is installed on and re enabled it and set to 8GB. It seems to have returned the smoothness to my sim. 

Could it be network/bandwidth related?

I wondered if it might be server load but I guess that wouldn’t change from patch to patch unless it’s especially noticeable just after a patch when everyone wants to try the new build.

Therein is one example of how other factors beyond something the patch introduced can be responsible for what people will ascribe to the particular patch.  Not always of course but it happens.

I have some of the LA area cached now. I'll try another flight through 'Stutter Gulch' with my network turned off to see what happens.

I did not expect this! Numerous pauses experienced on approach to KLAX with the network disconnected. No photogrammtry in off-line mode even though I have much of the area cached medium to high level (cache was created after 1.10.8.0 installed).

Is there a MSFS log file? Curious if the sim is throwing errors or something.

VERY hard to troubleshoot these things there are just so many possibilities.
