This is for CPU limited ppl, what happens is that there is a background process used by MSFS, and if it is delayed the sim will stutter, by lowering the sims priority that background process will get enough CPU power to finish in time. So overall you might lose 1-2 fps, but it will be smoother.
This is the point 1.) and 2.) in wuper0737’s post
3.) is more for CPU limited ppl with 4 cores (if you have more you are probably fine) , this is some parallel computing thread management code magic bug where different threads are waiting for each other, looks like if the thread boosting is off things go smoother, also probably costing 1-2 fps overall but eliminat the stutter.
As it looks like MSFS bottleneck is the CPU for most ppl. Any gpu 1070 or above have no real problem with high settings. but any cpu with 4 cores, I would say i5 6600 and blow have massive stutters and low performance.
SO if you have a system with more than 4 cores and a 1070 or stronger GPU, MSFS should not give you any problems, if it does 1 of the solutions in this thread will make it butter smooth with reasonable ingame graphic setting, the sim can do it. If you have system like this or below, basically no matter what you do it wont be truly smooth, time to buy a new CPU and motherboard.
At least this is my observation after reading everything and tinkering for 4 days now.

I have a 6 core CPU (Ryzen 5 2600x) and disabling Thread Boost benefited me with no or minimal FPS loss so I guess it doesn’t harm you by enabling it. Always worth a shot!
Thanks for the detailed post. Did you share this info in a zendesk ticket? Might just help to even point them to this thread
I have stuttering issues and the Lasso thing didn´t do the trick
No matter the graphical level, stuttering is permanent, even if I manually cache the region i´m testing
It´s almost unbearable
I have a i7 6700K
32 GB ram
GTX 1070
sim is installed on a new dedicated SSD
Does anyone have the same specs than me?
Sorry to hear you’re still having issues. I think too many people are encountering stutters for it to be only related to Hardware. Optimizations will come for sure, hopefully soon because the stuttering is indeed quite annoying. Some of these tricks helped ease it but its still existant.
Tell this for me having stutterings and some areas with low gpu usage with a i7 9700k
I don’t know - maybe I’m one of those lucky few who have no issues to mention - I’m on R9 3900x with 2080 Super. I do not pretend to think I can run MSFS at 4k Ultra (last MS simulator was not able to run on highest settings on release, it’s pre-built for future hardware), so I settled on high with ultra clouds. Heck, if you go as far ahead as P3D, running on high settings presents issues in some cases.
What I have discovered - my 70mb connection pulls the world data just fine - I get a very short hiccup now and then - not like I didn’t have those and worse back in the day when I was running P3D v3 and battling OOMs daily. What I have noticed is that the sim is a lot smoother even on low FPS and is ‘playable’. That might change with quality payware aircraft who relly on FPS for sim updates - but that’s to be seen yet.
Back in the day we were aiming for smooth rates, not maxing out 60 every second. Maybe that changed…
Just my 2 cents
Do you have hyperthreading enabled ? Turn it on if not.
You can check if you are CPU limited by turning of all traffic (cars boats included) and lowering the terrain lod and object lod to minimum. If you are still getting stutters like that, its not your CPU.
What I wrote is true only if everything else is perfect on your system, you have a great internet connection and fast SSD, your windows is clean , no background process is bogging down your system ect ect.
I was find with 30 FPS in FSX, but it looks like modern games messed up my expectations, is SEE 30 fps, its just not smooth enough for my eyes. At 40 fps this feeling is gone, so I’m aiming for that currently.
Smooth at 40 fps with good enough graphics. 60 would be awesome, but not happening until I get a new PC

I fixed the stuttering, and it was so simple, I can’t believe I didn’t check that first… the solution for me was to turn off Spadnext, I didn’t check it before because I had no problems in the alpha and beta versions, but this release version messed up something related to simconnect.
Until there’s a fix, I won’t load spadnext.
I7 9 gen, doesnt have hyperthreading. 8 logical cores. Nope all setring from low to ultra result at same issue. High end at most about 70 60 ultra about 55 45 limited by gpu ar most, wuth no explanarion issues and limits with g3000 and airliners
Do you run any external pp that uses sim connect ? It is known issue that it cause stutters right now.
I’ve found a weird approach that worked for me to hugely increase the frame rate running FS on a PC connected to a full HD display at Ultra settings. The PC is also connected to a secondary full HD display. I detached several windows (map, ATC, weather..), something that per se had no effect on the fps until I moved them in to the secondary display, at which moment I could see the frame rate boost reaching 3 to 4 times my initial frame rate.
I know it’s weird but it’s working for me. The more windows I detach and move to the secondary display, the higher the fps.
This however did not eliminate the stuttering I still experience sometimes at heavy scenery airports even with all the simconnect clients disabled.
This has been reported many times but its misleading. Your frame rate counter is probably adding up the frames for each window. I wish it was a eureka moment but the search continues…

Tried a couple of the settings listed in this thread and have seen some good improvement. Less stutters and pauses now, solid 60 fps. Very happy.
Yeah, I think you are right. Its just the fps counter going crazy. Closing SpadNext and all the Simconnect clients is what’s really helping.

My solution for now is to just use a slow simple plane, such as the Robin. That way it’s smooth most of the time. Also make sure you have as little stuff as possible running in the background.
Nope . Not a single addon
And for anyone hoping for a fix for the stutters in the patch due next week. Nope.
