You will find the stutters / pauses are there without the new mesh (try it).  It was really bad for me last night again from Zell-am-See to Salzburg.

 

 

What server were you on?   I was flying with a pal in that area yesterday evening on the EU north server and it was stuttering and pausing horribly for both of us.  We switched over to USA East and it was immediately smooth as butter.

 

Honestly, this is what makes diagnosing issues so difficult as im now convinced so many of the issues are server related.   I tend to fly on East USA most of the time now even though im in the UK as I tend to see far worse performance on the EU servers.

I do wonder about this, but I don't fly multiplayer.  Does it still make a difference?  Can I swap my server even when I fly solo only?  I will have to take a look.

I doubt it makes a difference in multiplayer or not.  The majority of data being streamed is scenery related.  I dont notice any performance difference with multiplayer on personally. (I'm locked at 30FPS and it doesnt dip below that either Multi on or off..  there probably is a small hit to the max frame rate with  multi on but i havent checked...as long as it doesnt dip below 30 for me i don't bother testing any further than that 😉 )  

Just hit ESC at any time in flight and you can swap servers on the fly.   Give it a go next time and see if it makes a difference.

After activating it and restarting MSFS, the new mountains were great (the difference was like night and day), but the pauses and stutters persisted. 
I was getting the manipulators / GPU at zero utilisation issue a lot. (Which I have had in this region going back months - other areas are fine).

Same experience with me yesterday. I assumed it was due to the mesh since the stutters disappered when I deactivated the mesh and reappered when I activated it again. 

I tried various things to sort things out before I realised it could be the mesh: dialled back the overclock, deactivated Process Lasso, fine-tuned the network settings (realised that for a long time XBox Live was not using open NAT as I didn't have UPnP enabled in the router). I logged out and back into my XBOX account and changed servers back and forth. I disabled all live services from the in-sim menu and even turned all the visual settings way down to low. Nothing influenced the stutters. 

I agree that MSFS seems incredibly unpredictable. Most of the time my system runs smooth with very little stutters and no pauses. Just the normal fps drop when flying into dense metropolitan areas. Since my system and graphic settings stay the same, I have often assumed that some of the changes in performance is due to streaming issues from the live services. It's a potentially fragile system, relying on so much data streaming over the internet in order for the sim to work correctly.

I didn't go into dev mode to check this. But while the stutters occured, strangely I had lots of headroom - CPU, GPU, RAM, VRAM. I didn't check all CPU cores though, just total CPU usage. 

Also strange that stutters persisted with visual settings all the way down to minimum.

Yes, it is another 'thing' that I have been trying to trace for some time now.  Frustrating!  When I get pauses, it tends to show a gap on the 'manipulators' part of the graph in dev mode, and I can see GPU, or CPU, or both, drop to zero utilisation during the pause, like they are waiting for something else.  I use other graphing software to confirm this also.  (cooling and temps all fine by the way - all cores on the CPU and GPU at about 70C).

I have given up trying to trace it now.  I can only think it is waiting for online data.  I will try the server swap tonight when nit happens.

Wow, this is fantastic. Now I can finally recognize the mountains in Switzerland. It‘s not perfect but what a difference to the default mesh!

A 20m version is out:

https://de.flightsim.to/file/14818/austria-20m-dem-high-resolution-terrain-elevation-data-from-lidar-imaging

I had performance issues with 10m. Terrain resolution with 20m looks almost as good judging by the screenshots, and still far better than default. Will try this one out - the 10m version became unflyable for me due to frequent pauses.

By the way, I’ve got Italy DEM 20m too so now have a large region of high resolution terrain in Europe. If someone does a LIDAR of Switzerland then most of the Alps will be covered.

The guy who made Austria also has Switzerland DEM 20m on flightsim.to

Yup, and he also had the German Alps region done.  There is also 20M DEM for Norway and the Canaries released as well!

Great!  Thanks for posting this.  The good news is the 10 and 20 don't look much different, but you can see they are both far, far better than the default.

Yes, I will definitely get both of those.  I love flying in both Norway and the Canary Islands.  This is giving the scenery a significant boost in my opinion.

These new DEMs have made me realise how great MSFS can look.  Can anyone tell me what the default MSFS DEMs are, particularly for the UK, Europe and the US.

The Norway one will get obsolete with the next World Update that comes out in June.

Just downloaded the Swiss DEM which I am looking forward to trying.  I will search flightsim.to for a few nice airfields to go with it.  

I've also just downloaded the chairlifts and cable cars scenery which should compliment it very well.

I too will probably give Norway a miss until I see what the next world update looks like.

That's great, didn't know that. Will download.

Also a definite download for me. Norway in particular looks much better in real life than the sim - updated terrain resolution is much needed here.

My question also. In particular I'm curious in terms of DEM in France after the recent world update. Couldn't find specific info on this on the official website.
