Hmm I think that is back to front. The problem seems to be more that it’s designed for computers of 10 years ago, when clocks were getting faster and cores were few. Clocks aren’t really getting faster any more but the number of cores is ballooning.
Sadly it seems from PC users that this game is most often mainthread limited, which means it can’t get the benefit of all the cores. A new computer in 5 years time is going to be just as bad as a current computer unless they rearchitect the code and solve the single threading bottlenecks.
I’m not sure that throwing money at this is going to help, unless the money is paying programmers to fix the code.

Computing problems obviously differ. Some are CPU bound, some GPU bound, and most are skill/knowledge bound. One developer may say a thing is impossible, then another creates the Unreal 5 engine, and knocks everyone else for six.
I suspect that software that is CPU bound is probably not a sign of insufficiently advanced hardware, but insufficiently advanced software.

I upgraded from a GTX980ti to an RTX3070. Although I do get smoother performance with little or no stuttering, the performance increase (although noticeable) is not going to be as radical as you might think.

Generally in CPU limited situations (which we can all easily find ourselves in with this sim), the trick is to balance the GPU/CPU load more. When GPU isn’t busy / loaded enough it sits there twiddling it’s thumbs waiting for CPU to produce more data. You can see stutters when this happens & CPU mainthread limited situations and GPU not being used much, especially if we are talking higher end GPUs.
You are running at a resolution of 1440p so that is quite a light workload for a GPU like a 3080ti (It’s a 4K GPU). So I would try increasing your GPU workload to balance the CPU/GPU load more. You can increase your GPU workload by -
- using most graphical sliders-> ultra (BUT NOT TLOD/OLOD or clouds {leave them as high, initially any way})
- increase render scale (so say render at 4K instead) and output at 1440p (this is a major if not the major GPU loader)
Keep increaseing the render scale on the GPU in FS until you come out of CPU mainthread limitation in your FPS counter.
Your CPU loading is driven by TLOD slider (150 should be fine, you may get 200 if you balance things out first), clouds (maybe turn down from ultra ->high) and AI traffic (of all kinds, so reduce these to say 50%, airport traffic, workers, cars, ai aircraft, shipping etc). These will all help lower CPU load a bit.
The trick with FS and PC’s is to balance your CPU/GPU loading though. You should be able to get better performance doing those steps.
Also once you have balanced your system, the 30FPS VSync trick is good for smooth operation, but only after you balance your CPU/GPU load first.

As previously said, your rig is just fine! The issues seems to come from the game itself i.e the latest Sim update. According to Asobo this is still under investigation. Personally I am also affected at the moment, even with my high end PC as well. Reducing the Sim settings (even moving the Render Scale below 50!) won’t make it better, I am playing in 4K and get around 25 FPS on every airport, even if I am in a far away location as Patagonia! Adjusting Nvidia settings have not worked for me neither.

I’m running 150 TLOD on my rig which works fine for me and I don’t think I need more than that, I can get around 45 FPS with A32NX average and more than 60 with A330-900 and PMDG 737.
After what we have done together, I haven’t changed a single thing from my performance settings and it just works fine.

Same here I didnt notice too bad a degredation after SU9 either. Maybe the odd stutter or two more, but barely noticable. Worst case is taxiing and changing direction is busy airport funnily enough.
Also saw some smoothness improvements with latest NVidia driver that came out thus week, but that doesnt really matter if you dont optimise your system.
Glad to hear your system is still doing fine, yes 737 is great framerate wise for a complex aircraft. Hope it stays that way.

I guess I haven’t seen it, I’ll try to update it tonight, thanks !
For me, it sounds like the i9 is overheating, and thus, reducing its speed.
1- Are you sure that you have an appropriate cooler?
The given TDP is 125w @ standard speed = 3.5 ghz
if it is in boost @ 5.1 ghz (on all core, or 5.3 ghz on one core), it can be much more, at least 1.5x.
So your cooler should be able to evacuate at least 180w
For example, the Noctua NH-D15 accept up to 180w. So you need the same or event bigger, but not smaller!!
2- is the installation of the cooler well made? good contact with the cpu?
If you want to check if your problem is effectively the cpu overheat, you can try to put it in “TDP-down” mode , 95w instead of 125w.
You may be able to do it in your motherboard settings, if it has.
That’s right. An 11th gen Intel has the reputation to get very hot.
Someone else on this forum had a comparable problem and solved it by mounting a much better cooling solution.
You have no evidence their cooling solution is the problem though. It would have to be a pretty poor cooling solution if it were so. Quoting the make/model in use might clear this up.

Hello guys !
I keep on checking my CPU and GPU Temperatures and at the moment they look Ok !
My GPU max 65C and my CPU 80 max ( Usually 60 - 72 ) .
From the day i changed my cooler to a Water cooler , No more Pc Shutdowns and Overall my Pc runs Ok !
I keep on trying different settings and Today i got better frames everywhere !
LOD 150 ! If i increase the Value then i get Frame drops .
I Turned On Vsync and locked my frames to 30 . ( smooth Performance )
The First One Vsync Off
On
Btw
My Monitor is a Samsung 34’’ C34H890 Curved 3440x1440p at 100hz
No G-Sync !
Here is my performance on a much lower spec machine .3440x1440 100hz i7 10700KF 2060super render scale@100 .Settings Ultra and High.
Biggest fps killer setting TLOD. Have that lowered to 130! Atlanta airport is the heaviest place in my sim.
I normally increase the TLOD when I reach cruising! Either way with your specs you should be getting double the performance I am getting!
@WarmedxMints Keep in mind 2560x1080 is nowhere as demanding as 3440x1440.

It doesn’t make much odds to the cpu which was the point. Their gpu isn’t struggling atm. They may need to lower settings later as the gpu is spending time waiting for cpu atm. I would be interested to see the clock speeds on the processor since it looks like it isn’t boosting atm.
if the cpu is too hot, it doesn’t enter in boost. and can stay at 80°. but you wouldn’t profit of the maxlmum perfs that it can do.
So you think there is no problem, even if there can be one.

Hello guys !
After many hours of experimenting , i finally managed to increase my frames !
I followed CkTheWinner advice and also Best Graphics Settings Guide ( From Flight Simulator Blog ) !
Now i get frames from 35 up to 65 !
Much better than before .
I have also Noticed that by lowering my Display Resolution to 2560 x 1080 instead of my 3440 x 1440 i get an additional Frame boost up to 80 frames !
I have Increased many of my settings to Ultra , the only thing that i have decreased is my TLOD to 150 ( From 200 ) ! I think this one is a Frame rate Killer !!
At the moment i am happy with the results , despite Microsoft’s SU 9 which many simmers suffered a heavy frame hit !
Thank you all for your support and assistance , much appreciated

My CPU from the day i bought an Aircondition in the room it does not go above 65 C .
So glad to hear you got it sorted. I built a new rig myself about a month ago. 3DMark Time Spy benchmark is vastly improved: 16362 vs 9412, a 74% increase. Fire Strike is improved as well: 35440 vs 24627, though not by as much at 44%.
Performance in MSFS when flying in VR returns low 30’s to mid 50’s depending on the aircraft and airport. However, what my eyes report is a vastly smoother and more fluid, stutter-free performance. Detail is sharper because I am able to increase both the LOD and TLOD.
My takeaway from all of this is that the overall balance of workload between the CPU and GPU, with help from fast memory bandwidth, may be most important as opposed to simply measuring the frame rate alone. One thing to also keep in mind: this is an online experience that relies on steady-state network throughput on both the server side and from your local ISP. If either (or both) are having issues your performance will suffer, and you may even have a CTD event if the data stream stops. There is no way to avoid that limitation.
The online community is a great help in solving problems, and was influential (if not essential) in the choices I made for my new build. Especially when it comes to VR, I would not be getting the results I’ve had without the input from the members of this forum, and other trusted online resources. So, thank you. 
And again @TeemingChief986, very glad to hear you’ve got things sorted and are able to happily fly in MSFS, with help from the community. Enjoy your new rig!

I’m so glad that it worked for you. It also worked out for me and now I’m probably one of the happiest person in terms of performance.
But of course the credits should always go to @BragRaindrop933 and the creator of the youtube video that suggests settings adjustments which we also posted in our post. I really feel like it’s gonna work out for many people who have the performance issues. I might consider opening a topic in the ‘General Discussion’ since where our topic stays right now, is not much visited.
