Yeah its pretty bad when your rig meets all the recommended specs and has an issue playing it. They need to fix this or people are going to lose interest pretty quickly. I have two outstanding issues and they still have not answered them. So far F- for customer service. Hope you are reading this MSFT
I am worried that when a fix is provided for higher specification machines like yours, a change may not be compatible with my lowly i7-2600K which is doing very well at the moment. Charles.
I donāt think itās the driver thatās responsible, I may be wrong. I found an interesting post which shows that post-processing is enabled by Asobo within a configuration file. The advise is to set to zero some of the post-processing effects. Here, I will give you the link ā¦

After following the advice from the link above, everything especially towards the horizon looks much smoother and less shimmery. It should be noted that I am using Nvidia Freestyle for post-processing and did not realise that post-processing had been forced by a configuration file set by Asobo. I was probably getting a conflict between the two.
I believe the author from the above link made his post to show how cloud edges can be improved.

Hey @TheAviator3506, have you tried the Highonsnow Glass Cockpit fix? Iām getting between 15-19FPS extra on the Airliners after reducing the CPU drain of those glass cockpit instruments, irrespective of what frame rate your monitor is running on (this has reportedly better performance in this fix compared to some existing frame rate tweaks out there).
Hi, and thank you for your reply. Yes, I have tried the frame rate fix for the glass instruments however, I prefer smooth updates to my instruments. For the time being, I am avoiding the airliners as the GA aircraft are fun to fly, (at least the ones I have tried). I do like private jets and wish Gulfstream would allow someone to model the very elegant G4! Keep safe. BRGDS. Charles
I am getting smooth updates with this fix and others appear to be getting much better performance with no visual impact on the instruments. I found the game unusable prior to that as it was taxing the CPU hard due to those instruments not being optimised.
Highonsnow, pls can you provide me with the link to this file because there are several in circulation. I may not have the best optimised version. There are three different file versions available on one website. BRGDS. Charles.
OK, I think I have found it

Hi, I have the same CPU I7 3770k with a GTX 1080, 16GB DDR3 2133Mhz. Unless you have a good reason to stay on stock clocks, I suggest to OC all that as itās really easy and you will have 0 risk if you stay light. For example I never touch voltage. I n bios I just changed the core multiplier to 44 so I run at 4,4Ghz turbo speed (vs 3,9), and changed the bios cpu fan control to be at 100% sooner, the GTX 1080 is, thank to MSI Afterburner, Oc too at 2100Mhz for core (+150) and 5400Mhz for its MEM (+400), with a fan change to run at 100% after 74 degres. The DDR3 is sold for 2133 but I chosen 2400Mhz in Bios and all work fine. I really see a big difference in MSFS and in general for all games . Iām really happy with my good old machine. Just my 2c 
Edit : I forget to say I have a good refresh fan for my cpu, a Noctua NH-U12P SE2 which help to keep temps under 82 degres.
Some people are getting significant step-upās in performance by using Nvidia driver 452.22, itās a Nvidia hot-fix driver that has no published fixes for the current 452.06 driver. Itās best to use the DDU tool to remove an older driver so you can have a thoroughly clean environment for a new driver install. I never use Windows to uninstall a display driver. Make sure that your current installed driver has not been rolled back to an older version, Windows can do that behind your back without you noticing. Certainly, a driver re-install gave me better performance. You will notice that some people report a significant improvement in performance while others get nothing. Itās all very strange! Charles
Hi Charles,
This is the original thread for the fix (just updated a few minutes ago with a new release of the fix, v0.1.03 September 9th 2020)

OK, many thanks for your link and work. Will take a look tomorrow. BRGDS. Charles.
Thanks man for this patch.
Iāve had numerous performance issues and had no idea why. Iāve applied this patch and I can now fly in G1000 planes at a constant 40fps

Brilliant, Iām glad itās working well for you!
Fix for those who are facing CTDās on installing/mid flight, main menu. CTDs Temporary Fix (Awaiting Patch)
i7-9700k, RTX2070 Super, 16gb ram 3200mhz.
Horrible stuttering when approaching any airport, almost crashes on approach.
Have tried with and without overclock. No fix even with low settings.

Ryzen 9 3900x 32gb ddr4 3200mhz here and most of my 12/24 cores are below 6% usage. In 2020 this should not be a thing anymoreā¦
I have the very same thing. Game is smooth other than regular 2 to 5 secondes drops to 10-12 fps whenever, it seems, some parts of scenery loads during flight.
However, on most approaches/final (and only there) I get massive stuttering where it goes as much as making sounds stutters too, sometimes even crashing the game. This phenomena only appears on final. As soon as Iām landed, performance goes back to normal with the airports corresponding FPS (like when cold and dark or departure). Thatās odd!
There are a lot of drop in the global GPU usage. And drops create lag in the game. For exemple when you change camera, or when you move in the cockpit.I monitor my specs during my flights and the problem is still there and only on this game.
This is the most likely cause tbh. I havenāt tested turning off all online function but it makes sense. Itās ok in Beta because limited amount of people are ādownloadingā streams. Once itās in the wild, imagine, 10 billion miles flown. How would the servers cope with this insane traffic?
What Iāve tested though it extreme manual caching. I cached the whole Toronto Area on high, 7GBs worth. And the whole KSFO on high, 21GBs. The KSFO still hiccups as my CPU is bottlenecking but Torontoās smooth with the manual cache. Load times are drastically different too with Toronto loading much quicker with manual cache. Without the cache itād load about the same everywhere, UK, Tokyo, etc. But with the manual it loads way faster. KSFO is insane, even with cache, itās over 1 minute staring at the screen.
Everythingās on SSD btw.
With your streaming theory though, wouldnāt it make sense that if youāre flying over 300 kts low to the ground could make this way worst? Like a jet perhaps? I donāt fly jets yet so.
