I disagree, a CPU bottleneck is manifested by no change in performance when moving from one GPU to the next, but in the benchmark video, the section with Ultra settings we can clearly see that there is in fact a tangible difference between the cards. The video does show a CPU bottleneck only in the 1080p with Medium settings (5:08 in the video) where you can see that anything higher than RTX2070 will not yield any performance improvements. You can see the GPU bottleneck (around 4:25 in the video) where there is a clear difference across the tested GPUs.
No good. the i7 9700k does`nt support hyperthread on my mobo. Asus z390e gaming.
I am running it at all cores synced 5ghz per core. Watercooled so stable and temps under load around 60c. Mem on XMP1 at 3200mhz 32gb.
Its not your mobo thats stopping you from enabling it, a 9700k simply does not have hyper threading. Not that you need it, you have 8 logical cores, which is great.

I7 6700K with a GTX 1070 8gb card here. After following the performance guide on the forums, turning the extra toolbar panels, as well as running the program as an administrator outside that of the Microsoft Store the sim is perfect for me now. No more CPU lag or anything.
Smooth running the TBM around Boston and the NE.
My advice would be to follow the guide, make sure HT is on, run it as an admin, and turn the extra toolbar panels off.

I have a 4460, 16GB RAM, a GTX 1060 6GB on a HDD an I have a really poor performance, unplayable : 10-30FPS with freeze.
It sometimes freezes for few seconds either in 1080p or 1440p no matter which graphic settings I use.
When I enabled the dev tools to display the framerate, it showed I was usually GPU limited (30FPS, itās ok to play FS) and from time to time, it freezes for fez seconds with mainthread limitedā¦ I can record it and upload for more details if needed.

You are right guru. Thanks.
Yes I am sure your right and I am tempted to make some small adjustments in the next few days.
Thanks

Itās great that itās playable for you, but your GPU shouldnāt be at 50%. That means itās only working half as well as it could be; it should be at 100%. Itās the CPU that ideally should be a low utilisation percentage.
I would turn vsync off completely - not set to 30 or 60. We shouldnāt have to do this, but it would seem - at least anecdotally - that itās causing problems on a few peopleās machines.

This video really adequately describes what is going on with the performance of this game. My 9900k 5Ghz, 32 GB, 2080ti system is CPU bottlenecked when running at 2560 x 1440p resolution on ultra.
I have found reducing the LOD to 130 instead of 200 helps. In non populated areas, like Patagonia I get around 64 fps. In large cities I am seeing over 20 GB of RAM usage.

I think thereās a big bottleneck by memory bandwith. My specs are i7-7820X (Quad Channel Memory), 32 GB and a 2080ti. MSFS runs smoothly at 70-80 FPS @ 4K, max. settings. GPU load is about 90-95 %.
Iāve done a test and reduced RAM speed from 3600 MHZ to 2133 MHz, FPS dropped to 30-40 FPS with GPU Load only at 50%.
Maybe someone else is able to confirm this ?
i have the exact same processor with a 1080ti. i get decent FPS but terrible stutters. i will have 60 FPS but when i pan around with the drone camera it will be stuttering all over the place

Itās funny how weāre trying to play a game that was supposed to be revolutionary when it comes to simulation yet there is still pretty much zero multi-core / multi-threading support in the year of 16, 18 and more core processorsā¦ What is even the point in upgrading our rigs if developers keep writing games that rely on single core performance.

Doing that actually made me gain about 15 fps. Used to get 15-20 fps in the 747 and after doing that Iām getting 30-35
Iāve got 4 core, 4 thread i5-4670k @4.2GHz and outside cities also able to have 50-60 fps with highend settings, but it stutters and spoils the whole fun. Iāve tried everything I read in this forum and nothing really helped. This stuttering is killing me
This worked thanks! but now Itās how do I say it microstuttering and still using 100% cpu but in different stuff not only on MSFS.
In my case HT didnāt make much difference, the two thing that helped a bit in my case, rolling back the Nvidia driver and limiting the framerate externally. However, it does not eliminate the stutters entirely but helps a bit
Your processor does not support HT, but it does have 8 physical cores, so if you have lost performance or are having a lot of stutters, the root cause may be something different than those of us who have seen a big boost when going from 4 CPU threads to 8

Have you tried setting your processor scheduling to background services? I have the same CPU @ 4.1 and it got rid of the long duration stutters. Thereās still microstutters here and there, but itās an improvement.

Gosh, makes my heart so happy to see my post getting linked over and over (I am reddit OP.) I too am still seeing the microstutters, and am working on further optimization to try and see if can knock those out as well.

I have a theory about the NVidia driver, and the complaints that the release build made performance worse. In the past, before this driver, we were told by support to enable āThreaded Optimizationā in the NVidia driver settings to improve performance on CPUs with many cores and Hyperthreading. Now I see that the new driver comes with those optimizations enabled by default, in a dedicated profile for Microsoft Flight Simulator:
Maybe thatās one of the things that causes problems for some people, possibly those that only have 4 cores, and no Hyperthreading, or people that disabled Hyperthreading. Maybe in those cases the simulator works better with the default driver settings, where āThreaded optimizationā set to Auto.
The new driver also enables by default Vertical sync in Fast mode, in the profile for the simulator. Thatās something worth investigating as well.
