Limited by main thread, stutters throughout entire flight

ISSUE DESCRIPTION

Description of the issue:

I have been having a burst of three stutters for the longest time. I will happen in all phases of flight. I have tried everything from a new windows reinstall, disable antivirus, admin, high priority, changing graphic settings, drivers, etc, I have tried. my mainthread response time will jump every time I get the stutters. They are always in three round bursts and will happen every few minutes.

no steps are needed as it will do it just sitting on the ground cold and dark.

YOUR SETTINGS

If the issue still occurs with no mods and add-ons, please continue to report your issue. If not, please move this post to the User Support Hub.

What peripherals are you using, if relevant:

i9-12900k, RTX 3070, SSD, 32 GB 3200mhz DDR4 ram

[PC Only] Are you using Developer Mode or have you made any changes to it?

Yes and No, no changes with it on or off.

[PC, MSFS 2020 Only] Are you using DX11 or DX12?

DX11 and DX12, no changes in stutters.

[PC Only] Many issues may be due to an outdated graphics card. Please state your Graphics Card Driver Manufacturer (NVIDIA, Intel, AMD) and Version: NVIDIA RTX 3070

As it is happening on a very regular basis there is likely something else on your system using resources. Try having Task Manager open and see if anything pops up when this stutter happens that might give you a clue.

I have done this as well. I dont see any changes that are odd (no spiking anywhere). SSD is not stuck with any caching and is keep up, and internet is keeping up (gig up and down).

Moved to User Support Hub that is more appropriate for community support.

Anyone got anything else I should try? Still at a loss.
