My config :
I7-9700, RTX 2060 super, 32 GB Ram, MSFS installed on a non-system SSD, 1080p, 4G internet connexion (around 100GBPS).
I maintain a nice 50fps even in the dense areas, but I still had stutters, regardless of the game configuration and density of the area. I play with a track IR, which doesn’t help I think, because it encourages abrupt vue changes.
I just disabled the rolling cache (which was on the same SSD as FS). After a couple of test flights, my problems seem to have disapeared. I need more thoroughfull testing, but I think it’s an interesting lead.
The combo works great for me too. I just want to thank to all the people that is helping with their effort to make this sim much better. I really appreciate all this research and the fixes you share with us. Thank you so much!!!
Hi, I have similar specs with you. I got 6800K instead. I think the stuttering is caused by Turbo boost 3.0 which all Windows programs will try to compete with you using the boosted cores.
I have seen some people on avsim talking about MSFS is going to slow the whole thing down if a single core (thread) cannot keep up with the others. For this reason, when your boosted core is utilized. Your game will stutter to wait for that core to finish it’s assigned task.
If you observe your logical processor usage. You may find 1 - 2 cores constantly firing at 100%. I use Lasso to set CPU affinity of Flight Sim to stop using those cores. And yes, you do lost a bit of process power. But the overall experience is just much better as tasks are spread evenly against all other cores. The stuttering issue goes away too. It will always be the same cores, as Turbo boost will find the best quality Die(s) for frequency boost which doesn’t change.
I tried a 2K Ultra-ish setting with an Overclocked GTX 1080. Getting a decent roughly 30 FPS under heavy storm at Heathrow. The machine is obviously not powerful enough to run higher FPS. But no stuttering issue is a big plus. Hope this may help you enjoy the flight
Hi, I figured it out that it was spadnext software that uses simconnect, turns out that there’s a real issue with simconnect, didn’t know about that
that eliminated all the stuttering.
Thanks anyway for the info!
My problem was trying to run streaming along with the game. After I made OBS to use different core sets from MSFS. The stutter seems to go away. You may have a chance to use spadnext with the game by doing that too
I think there’s a catch here. It is that when you detach a window. Windows seems to treat it as a different game. When you move it to the second display. Your GPU may decide to render it in a different way.
In my case, I have two graphics cards plugged in to my system. I attached both cards to different screens. And guess what? When I move the detach window to the second screen. The other graphics card picks up. You can see the load of the first graphics card decreases (and FPS goes up) and the second card’s load increases.
Try starting in large/dense airports and fly in big cities like Tokyo and New York.
It shold make your CPU sweat.
You can also increase the amount of traffic in traffic settings, both airport, boats and roadtraffic hits CPU.
I’m not having any issues of stuttering on my PC in FS2020, but on a previous computer I had similar issues on a different title. I spent a lot of time, much like many here changing settings and then found the issue.
Overheating.
The title was ahead of it’s time vs other games I played so tested my system more. I found that while my game could keep up, when the temps got higher something was cutting in to prevent further increasing the temperature or it just didn’t like getting hot. When something loaded the load itself more often than not got there but the heat generated from it then had a knock on effect.
You may all have checked your temps as part of your testing, so I don’t mean to tell everyone to suck eggs but it would be worth monitoring temps while playing to see if any pattern of temp increases and stutters.
A good point, I had cleaned my computer, specifically CPU cooler, and it is better now, still some stutters. I guess the game stresses the cpu, which is a bottleneck for some, and good thermals should help.
Perhaps a CPU upgrade is even better, but that means spending money.
its another software independent of MSFS, if you don´t know it then you didn’t install it , check if you have another software that uses simconnect, or wait next week for the patch
Disabling the VFR map in the menu bar has improved my frame rate. Just go to the settings icon in the menu bar and disable the map and anything else you don’t need. Charles.
