Hello, i am new here.

I will start by giving you my components

RTX 3070 OC

I7-9700k

32gb ram

650 Watts psu, (Yes, it's not a lot but it works)

1080p

I can see that my gpu/cpu usage is low through the nvidia performance viewer (Alt+R) Normally 50% of use.

The pc temperature is within the limits.

Hello and Welcome!

It would be especially helpful if you can give more detail:

• Is your 9700 overclocked, if so to what clock speed?
• What are your graphics settings in MSFS?
• What are you considering 'low fps', and in what planes/airports are you seeing this?
• Are you using a Gsync enabled or capable display?

If you open General Settings in MFSF you can select Dev Mode and enable its on screen display for frame rate counting as it has other useful detail.

Of note, at your screen resolution, if you're PC is functioning as it should, you can expect to run ALL sliders at Ultra w/ the following caveats:  Terrain LOD is ultra hard on the main thread your CPU is running on its last core, 07.  This hugely is impacted by the scenario but if you're in a hard to process plane AND in complex metro airports I would start with a T-LOD of 140 or so.  Object LOD has little to no impact so you can set that at 200.  Also, you can set Aniso filtering at 16x and 8xSS is fine w/ your hardware and screen resolution.

MSFS is main thread limited. Your CPU usage will be showing you the average of all your cores but one of your cores will be at 100% usage.

Hello.

My 9700 isn't overclocked.

High settings, TLOD 200, Buildings Ultra, Terrain Data Ultra, Volumetric Clouds Ultra, Aniso filtering 16x.

I am having more or less 25 fps when at large airports like KLAX, And 35 fps at smaller airports whilst on the ground.

No.

I will send you guys an screenshot from my game at klax.

High settings, TLOD 200, Buildings Ultra, Terrain Data Ultra, Volumetric Clouds Ultra, Aniso filtering 16x.

Yes, a 9700k may struggle on the main thread at higher sim settings for sure.  

@714toto  Open Task Manager in Windows.  Go to the performance tab.  Right click on the CPU graph and select 'Logical Processors'.  It should now show 8 graphs for the 9700 instead of one.  Leave the Task Manager window open.

Start MSFS, select a scenario, and load.  When the aircraft is flying (maybe set autopilot), press alt-tab to find the Task Manager screen and you will see that 1 core, or maybe 2, are overloaded and running at 100%.  The rest will be lower, but the figure you talk about will be the average of all the cores.  If your CPU is slow, this can also affect your GPU to be slow, as the CPU feeds the GPU in simple terms.

Although the 3070 GPU is good, it needs a lot of help from the CPU in MSFS, which it probably isn't getting, or not enough help at least.  Your 32GB RAM is fine.

Even with a good GPU, MSFS is very CPU intensive.  You need to tell us your screen resolution within MSFS and other settings, such as ultra settings etc.
With a 9700, you may be fine for 1080, but at 2k you may struggle.  Certainly 4k will be out of the question with high detail settings.

This is true only when frame rate is unlocked, or CPU is close to being maxed due to high demand.  95% of the time in any plane anywhere the main thread is coasting along well below 100%.   I monitor CPU8 (where the MT runs on 9900K) and as you can see right now about to land at RJFR in the PMDG 738 it's running at 60% and this is typical:

Not sure I would call that "low fps".  Suggest setting the fps in MSFS to "half the refresh rate", assuming a 60 Hz monitor and stop looking at the fps counter 😉

TLOD 200

Set it to 100 and test.

Geez, it is SOfsimple, really: if your GPU load is below 90%, you are CPU limited. End of the story. And your dev mode indicator even reads it clearly: «limited by main thread»

Absolutely, or even 80.  I wasn't aware but just saw the relative diff between 9900K and 9700K and it's significant.   Be nice to see what clockspeed the OP is running at when taxed.  Should be good for 5Ghz w/ sufficient cooling.

Worked pretty well.
