In a post here a while back the user who created the community spike fix said that they thought some terrain mesh post-processing algorithms were being run on our individual user PCs, so it is actually possible that the Asobo spike fix caused this if they added more post-processing instead of fixing the actual mesh. 

The behavior described makes a lot of sense if the sim is loading a new block of terrain mesh as your aircraft crosses some distance threshold, then doing some CPU intensive processing of it, then stopping that processing until another block of mesh needs to be processed.

With all the marketing about MSFS being "in the cloud" I'd expect that they would run any post-processing server side with the fancy Azure supercomputers, and not on our individual PCs.  It's inefficient to have every user's copy of the sim doing that when they could run it once as the data is ingested into the servers. 

You might try reducing some of the terrain mesh detail sliders and see if it helps at all.

That all makes a good deal of sense. It would explain both conditions.

I am in the boot also, came in for me after the last Update with Patch 1.13.16.0 and still there with the yesterday update.

It`s all sporadically ( not to say for me how and when it happens ) and sometime it causes comlete holds up to 3-5 seconds and i don`t know why; nothing changed dramatic and i am not to mutch in Ultra most is High

and under.

I had a mutch better performance ( as i said nothing changed on the settings ) before, so..🤔

I will try that thank you.

Anything to do with this?

There are a few suggestions, the usual rolling cache off, live AI off, but now some are saying that disabling online functionality is the only thing that restores FPS despite low CPU and GPU usage figures.

I have never had Rolling cache ON and all live AI has always been OFF. I will see if there is anything else I could turn off. Thank you.

After doing a flight in the new PA28R I feel the sim is INOP.

Same for me since WU 3, frames drop hard but CPU is about 20% and GUP is less than 50%. I have one core that is always maxed out while the others sit idle. Is there any hope for better utilization of the processor/gpu at some point? i7 10700K@ 3.8 GHZ and RTX 2070

My sim was running so well the past week Ive done nothing else with lock down. After the update last night. At cruise app or really anytime out of no were FPS drop to 15-17. CPU is not blown out or GPU. Tested all day to try and find probelm.

But it seems am not alone.

I have no idea how to solve it. Tried all the things I know. Nothing works. I even see sometimes when in menus FPS 12-15. 

O dear....

Also sent a ticket in.

Check your rolling cache. Make sure its not gone to 8. change it to 32gb or better yet 62GB thats what I have done. and I also under the Vsync = on  increased the FPS limit from 30 to 60 so now I am getting 30FPS. Prior to this I was stuck at 15FPS and Internet thrrashing.

PLease read up Manny. I said I have never used Rolling cache 🙂 will try VS again last time it was bad.

Yes - but can you try enabling it David? Also, did you have any custom processor-scheduling settings set in Windows or through Process Lasso?

I assume you've already tried setting all your graphics and data in the sim to a default (med/high/ultra) exiting the sim, restarting and then configuring them again. Random suggestion but you can also try deleting your directx shader cache -> run Disk Cleanup as an administrator and there is a checkbox there for that.

If it is related to the spike fix and post-processing the terrain mesh (possibly the coastline fix as well, if they are "pulling back" the coastline in realtime on the users PC), then turning off the online data limits the terrain mesh to the simplified version that is installed on your PC which could significantly reduce the processing required.  

Can confirm I’ve experienced this too. Thought it was my old PC not being able to handle it, as otherwise it’s normally been very good. My rolling cache and photogrammetry are both off.

Btw I tried the Mappamundi spike fix again yesterday but it just introduced more spikes.

Same here....this update has completely broken my sim.  It was really working wonderfully before it and along with the Tree LOD mod looked and performed better than ever.  Now it is completely unflyable for me...a mess of stutters, pauses and awful LOD.  I am sidelining MSFS for the first time since Alpha testing....hope they can hotfix these issues or reverse whatever they did to break it but my guess is we will be waiting until the next major update ...

I have spent the all day trying everything out. Turning graphic to low then back, all on line date off etc etc. 

But it seems ASOBO see it.

I have the same problem with RTX 3090 and I9 10900K @ 5.3 GHZ. FPS dropped to 9 FPS from solid 77FPS.

I'm on there as well. From the FS Forum:

https://forums.flightsimulator.com/t/performance-degradation-with-1-14-5-0-upgrade/376202/5

The team is aware that performances can be impacted for some users.
We are investigating, thank you for your reports.

Disabling hyperthreading/SMT might also be something to try, based on the reported symptom of 1 windows task manager "core" going to 100%.  If that core is part of an SMT pair with another highly loaded core, it could cause things to not run smoothly.  The Windows scheduler is pretty dumb in my experience. 

Dreadful intermittent stutters here too. Started seeing them a bit with WU3, very noticeable with this update.

I had it appear update before last.  It completely destroys the enjoyment.  I am convinced it is scenery / mesh related as it is repeatable in certain areas.  It isnt stuttering, it is pauses or micro pauses.

I think it happened when they tweaked the sim to fix the spikes.

I tend to do a lot of repeat flights to test the sim after any update.  Before their spike fix I saw spikes north east of Saltzburg, but had good performance there.  Now, the spikes are gone but I get these terrible pauses.  I got so frustrated I just quit the flight last time. 

I think you are right: there were some giants spikes west of Florence, Italy. Now that's one of the areas where I see flashes and experience slowdowns.

This  (for me it is shure) is a Asobo coding thing and cant be fixed with tweaking around with the sim settings or Windows stuff.

I had a superb Sim before 1.13.16 and with yesterday's update still the same so i think this has nothing to do with settings..

cheers 😉
