Thanks for the info. Now to sell my kidney to get the new CPU lol.
well, I am sure that normal proc will do as well 
Any not too old i7 for a reasonable $$$ will do. My message was mainly that old 4 core i5 is really not fit for the job
I was just kidding a bit 
I intend to upgrade early next year

I also have a 4790K and noted the problem with 100 percent CPU saturation and low frame rates. I ran throughout the alpha with the same CPU with HT off and rarely saw the issue. With the release version I was seeing 100 percent CPU utilization almost constantly, and the sim was stuttering continuously.
Turning HT on helped tremendously, but it still does happen in flight occasionally, and it does seem to be worse at faster airspeeds with more scenery reloads.
Based on another userās suggestion, I changed the Windows performance profile in the Control Panel from favoring āprogramsā to favoring ābackground tasksā, and that did help reduce the CPU saturation even further, but it does still happen - especially in the A320.
Other than that, my old 4790K CPU (clocked at 4.2 GHz) does give very good performance in MSFS. I have a 1080Ti GPU.
The upcoming patch is supposed to address problems with CPU thread utilization. I guess we will have to wait and seeā¦

Which patch did you try? Did you try the Highonsnow one?

Those are wonderful CPU for the price theyāre on now. I OCed mine easily at 4.6Ghz, It definitely makes a difference on crowded area
I do have this patch installed too.
I totally agree with this. I noticed stutters when approaching cities at low altitude and complex airports. Once loaded, my fps goes back up. I totally think this is a big part of the problem. I think this could be resolved in some cases when in IFR mode, the sim can anticipate way ahead what scenery will be and buffer it ahead of time (especially for people with 32 Gig of ram. This could be buffered into the unused ram so it doesnāt have to be loaded in at the last minute.

i definitely notice frame rate drop while scenery is loading in.
Have you heard of a Windows 10 service called āRuntime Brokerā ? This service is associated with Windows Appsā There are some circumstances when Runtime Broker uses a large amount of PC resources and can āslowā your PC down. This happens when there is a problematic appā on a computer. It is worth checking to see how much memory this appā is using. Apparently it could be up to 1 GIG !!!.
I kill this service with a gaming optimisation tool along with Windows Explorer. My performance on my old i7-2600K is amazing compared to some of the poor reports I am hearing about poor performance on high specification machines. I have read that MSFS 2020 only utilises 4 cores, (as far as I understand) and that is why my old quad core CPU is managing to keep up.
Microsoft recommends that, if Runtime Broker is using more that 15% of memory that you should kill it.
My usage is 30% and it varies as you use your computer. I will check to see how much memory it is using on my system when I run MSFS 2020 the next time I run the simulator.
Itās certainly worth checking to see if Runtime Broker is a āRuntime BREAKERā if you are suffering unexpectedly poor performance. It was just a thought. BRGDS. Charles

After much trial-and-error, I now experience a typical FPS of 40-45 and virtually no stutters.
In detailed airports or over large cities, in stormy weather and at nighttime, my FPS rarely drops below 25.
All my tweaking has been conducted in the C172 G1000, so I still need to learn if moving faster over the ground will affect FPS and stuttering.
My rig is nothing spectacular, but the monitor resolution is relatively low:
Intel Core i7-4790K @ 4.00GHz
32 GB RAM
RTX 2070 v. 8 GB VRAM
Monitor at 1920x1200, 60Hz
300 Mbit internet
Initially I couldnāt get FPS above 30 unless I turned a lot of eye-candy off. I tried many tips in vain and experimented with letting GeForce Experience find my ideal settings.
What enabled me to find the solution was activating the monitor of MSI Afterburner and setting it to display GPU load, VRAM usage, CPU load of all 8 threads and RAM usage.
With a fairly powerful graphics card and a modest display resolution, I had convinced myself that the bottle neck had to be the aged 4-core CPU.
Much to my surprise, it turned out that the GPU constantly ran at 98-99% while no thread stayed above 70% for any length of time. The RAM usage barely exceeded 16 GB, and the VRAM stayed around 6 GB most of the time.
For me the answer was that I had Render Scaling at 200. I had no idea what it did (I do now) or why I had left it at max, but once I turned it down to 100, the GPU took a deep breath and settled around 80-85%, and apparently the rest of the system found more useful things to do than waiting for the GPU. And more importantly, the FPS increased by 15-20 points.
Iām no expert in these matters and have no miracle cure for those of you who are struggling, but the important lesson I have learned is this:
You absolutely need known how your individual hardware parts are performing when you try to tweak the settings. E.g., if your RAM or VRAM runs full, you need to address that, but if, like me, you have VRAM to spare, you may find that you can run with with Texture Quality at Ultra with little or no FPS drop as a result.

Hello, here is a video that can help you configure the options:
I have a 4GB GTX 970 and I use the nVidianInsector to configure some parameters, in particular I limit the fps to 30 with a vertical synchronization of 1/2 to adjust the 60 Hz monitor and I deactivate the vertical synchronization of the FS2020.
32GB RAM is recommended. I have got i7-10700 and 2060Super and I cannot run the game when starting at LFPG Charles de Gaulle Airport even in lowest graphic settings. After I added one more 16GB RAM, problem solved. Also, youād better check if any part of your computer working incorrectly, especially when same issue occur in other games on your computer.
I am seeing this same issue with stuttering to the point that I donāt even want to play this game. I have the following specs:
*i7 10700K
*2080ti
*32GB DDR4@3200
I feel like I have more than enough on the specs here, but always get the ālimited by main threadā issue in the FS integrated counter. I have tried every fix on the internet (process lasso, background priority, changing every nvidia control panel setting one-by-one, rolling back graphics driver, latest version of windows on a fresh install, all game files on my SSD, Vsync on/off, frame rate limiter, app priority, turned off traffic, tried offline mode), literally everything! I seem to see the same issue where 1-2 cores seem to take all the load and I know it isnāt a temp issue, as CPU and GPU are in the 60ās. I honestly have not idea what to do to get the stutters to go away. It has to be a CPU issue, but I cannot get anything to work.

Iām editing my previous comments about the update in performance. When I originally updated the game and launched I was getting worse performance then I was getting before the patch. After reading through some threads, I cleaned out my community folder and then rebooted my computer. When I launched FS2020, I was now able to see the performance improvements.
I was now flying over Toronto at 60fps in 2k Ultra smooth with no stutters. I hit much higher fps when I flew out into the rural areas. Good news and I apologize for my previous frustration. I hope other can find a simple solution as well.

hmm, donāt now what I am doing āwrongā, but since release I had no (yes, not one) issue. I have a n almost clean windows OS (always updated) with no extra software except steam and some steam games. (of course nvidia driver software).
I write this because I am currently downloading the new updateā¦
My Specs: Ryzen 5 2600, 16 GB Ram, MSI B450 GPM Mainboard, MSI RTX 2060 Ventus 6G OC, 1GBit Cable Internet.
Suggested Settings where High(?), second highest setting. FS run smooth between 15 and 50FPS (depends on where and how low i am flying)
So, update is ready, Iāll give it a try, hopefully everything runs as before
Yep its pretty bad on my end. Weighing out if I should build a new PC and wait for the 3090
Looks like it might be be time to build a new PC sometime

Well yes sir, I actually turned my render scaling to 90 as that makes undetectable results in my 1440p with TAA on. But fps boosted. I get around 45 - 53 on high with somethings off such as aniso and terrain shadows. But on my 3570K@4.4, 1070, and 16GB, dayum ya know, high clouds. I can live with that.

Just installed the update and also tried, because why not, to run at high preset (+ 16x AF, no AA, no texture SS, no DoF, no lens flares, no bloom) and it was a night and day difference to what I saw before. Music runs smooth in the menu, I get just a short moment of stuttering after loading up and getting into the cockpit, then I was looking at ~42ish fps on the ground and 65ish when flying, even though I stayed low in my Savage Cub. Not a single stutter, but I didnāt went far (rolling and manual cache completely off though).
Also, switching the VFR map back into the FS made no difference and I set the cockpit things refresh rate to low, which is in the graphics option now at the very bottom.
That update was a massive improvement on my end, at least thatās what I can say after a short ~15-20min flight.
