Agree with the above that we are pushing the limits of hardware in those areas as they can expose a bottleneck in RAM, VRAM, and bandwidth. These pauses used to occur even in previous builds but was able to eliminate them on my rig (I'm running 3840x2160 with ultra settings on a 2080ti, and do a KSFO circuit with live traffic enabled and multiplayer off to test).

 

Had made these "non-technical" suggestions in another topic if they help.

Under Windows 10 Game Mode settings:

- Try enabling Game Mode if it was disabled (and vice versa), 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

 

In the Win10 Xbox Networking settings:

- Check that the Teredo service is able to qualify (and click "fix it" if it isn't) 

 

In Geforce Experience:

- Disable in-game overlay

 

As far as hardware:

- Enable Hyperthreading if you can

- Enable memory XMP profiles if you can

- get the fastest GPU you can afford...! I've tested the sim with both my 10900 and old 5930 CPUs and the GPU is what scales performance more. 

 

Hope these help

All sensible stuff Dylan.  I do all of this, or most of it that I can do.  👍

Some of these are a toggle and seem to work differently for different people, such as the Game Mode that you suggest.  All you can do is try it both ways and see what works for you.

I am still confused over some potential settings to tweak, such as 'threaded optimisation' in NVidia control panel.  Some say it should be on, but I force it off in mine and seem to have the best performance.  It may be that threaded optimisation doesn't actually affect MSFS in any way though and it is all just a placebo effect. 😄

Watching your clip I realized that I already seem to be used to these stutters. I didnt' even notice them the first time I watched your clip. Needed a second time to see them. I'm getting older I guess. Taking life with all it's flaws ;-)

I'm getting poor performance in large urban centers like Los Angeles and Miami of a stuttering/pausing nature with the latest update. LA is by far the worst. Approaching LAX from the east, for example, I'm getting almost continuous random pauses lasting as long as one or two seconds. The sim is now unflyable for me in the A320 in this area. I've tried the route repeatedly including adding the area to the manual cache. Note, these are all photogrammetric areas. My sim and aircraft are totally stock - no add-ons.

Are others seeing this? Ideas to the cause? Some great changes in this update, but this stuttering is a show stopper for me.

My rig is quickly becoming a dinosaur, yet I experience very decent, stutter-free performance (37 - 42 fps which, for me, is kick-a_z) in and around Miami / Ft. Lauderdale area(s). Note, though, that I am running my dinosaur at 1080p (vsync off, fps unlimited [NCP & MFS], TAA, "High" settings, Render 100).

No, that's just how the sim looks with photogrammetry mode turned off. Some actually find the sim more consistently attractive that way, as its very much like a refined version of X-plane with Orbx scenery.

And as you can see, the lod is much expanded.

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.... 

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.

Had same experience last PM. John Wayne to LAX. Via GPS. Some stutters were probably 1/2- 1 second. Departed the FP en route momentarily, for a quick practice landing - I think it was at Northrup. Got back up and re-engaged the AP in the climb in my Xcub and all went to heck!  nose went up to stall angle. Couldn't control it. Disengaged AP and found the trim was frozen and inop. Switched AP on and off a couple times. Finally regained control just S.E. of the LAX pattern. I have flown this route multiple times without issue. Because the stutters were so long I also wondered if loss of control was somehow related.

I also am having bad stutters around Los Angeles since the update. Definitely going to have to turn some sliders down.

Just giving it a try. I didn't know that there were game performance related settings within Windows, knew only the ones in the Nvidia panel. Thanks for the tip.

These stutters in the LAX area (mostly east around PDZ) have been there for a while. They are not performance related, rather some strange pauses while the sim does something in the background. Watch your CPU and GPU load and you will see there are no spikes, it really seems like the sim is pausing.

Using the Developer Mode FPS panel, it shows that the Manipulators thread is choking at the time the hard stutter/pauses occur.  Anyone know anything about what this thread is up to?  Also I see that what ever thread(s) is on logical core 15, it (they) is pegging 100%, which is not usual.  Most of the time in this area, running on my rig that core is about 80 to 85 percent utilized according to the task manager's performance tab.

But then again, when these issue are NOT happening, DANG...the VC experience is spell-binding is its magnificence!

Edit:  Though GPU scheduler off-loading seems really cool, it's still a rather beta feature of Win10.  I'm not opting in, plus it's geared towards core limited systems.

Yep - agreed. My GPU and CPU are both snoozing, yet my sim is frozen.

Seeing this also. Very strange.

I can say that it's scenery related, since, when I turn down photogrammetry, LOD or Terrain Vector, I see improvements. Render scale, AA, traffic etc. have no impact.

If you switch down to 1080p, does it eliminate it entirely?  Or does it still have a stutter?

Still very bad at render scaling 50, which is equivalent to 1080p AFAIK.

Can someone please explain what you mean by " I guess it's to do with expanded LOD?"
