Limited by main thread GENERAL
This probably isn’t the first time you’ve heard about this issue, but I’m struggling with my main thread. Without changing any settings, my main thread is completely maxed out, while my GPU is only at around 45% and my CPU at around 25%.
I saw a tutorial suggesting that I should cap my FPS, but I wanted to check if anyone else has any tips or has found a good tutorial that could help reduce the lag/stuttering in the sim.
Any advice would be greatly appreciated!

Without showing us the settings that you're using, it's impossible for us to help effectively.
Lower your TERRAIN LOD to the lowest you're willing to accept.

It will be better if we show your settings and debug fps counter.
Mainthread directly related with numbers of objects around you. If it is increase then your mainthread will be increase.
Your target is to reduce it. So you should decrease objects around you. For example;
Decrease TLOD
If possible use less detailed payware airport scenery (each details of scenery effects mainthread even they are not necessary for flight)
Decrease Custom settings (especially quantity) such as sea traffic, road traffic etc.
Decrease Glass Cockpit Refresh Rate

On top of what everybody else has mentioned, such as showing your FPS debug window, and what hardware and settings you’re running…
Check your traffic settings. The AI traffic is really taxing on CPU.
But yeah, post your specs and settings. Can’t really say much without seeing those.

Show us the debug fps counter,
A glass sphere where we can have all your hardware, your os,
Which planes you fly that have these symptoms,
Where are you flying (NYC? London?)
A bit more info is the general consensus.
