Came across this stuttering fix on a youtube shorts, and after half an hour of flying the Cessna Skywagon (nice plane) South West from Washington DC, at 2000ft the micro stutters everyone complains about in fs2024 - they seem to have gone now.

You have to do this:

How to Disable HPET (Windows): [High Precision Event Timer]
Open Command Prompt as Administrator.
Run: "bcdedit /set useplatformclock false". (without quotation marks)
Run: "bcdedit /deletevalue useplatformclock" (optional, to restore the function back to default).
Restart your computer.

"High Precision Event Timer (HPET) is a hardware timer used in modern PCs to synchronize multimedia, graphics, and system tasks, often replacing older timers."

Have a Nvidia 4080 FE, AMD 5800x3D CPU, did use DDU uninstaller to uninstall nividia App & driver a day before, when I re-installed app and driver, made sure the driver had clean settings before install.

Did also update my ASUS TUF 550 motherboard BIOS a day beforehand.

Tried this with all sorts of graphics settings in fs2024's own settings, and its still smooth with each one - each time.

With DLSS on, Quality setting, DLSS off, TAA, High or Ultra graphics settings, with or without the external program 'Auto FPS' running (with Auto Method within Expert Options set to 'FPS Sensitivity')

You can usually see the micro stutters more when looking at the lower part of the screen, but it seems ok now?

Give it a try, see how you go on, can always put the HPET setting back to what it was before, as I have shown above.

This HPET function can also be changed with editing a registration value, which is essentially what you are doing when running this command in the command prompt. 😊

Also, in MSFS 2020 you could delete the rolling cache from within the sim to make it run better (supposedly), but fs2024 doesn't have the option to do that from within it, but you can still do it, by deleting a particular file.

The file in question is named: "ROLLINGCACHE.CCC", and can be found in the folder: (Steam version) C:\Users\name\AppData\Roaming\Microsoft Flight Simulator 2024.

Dunno where the Microsoft Store version is?

The file will remake itself when fs2024 is restarted.

So, thats something else you can do I suppose, that will help make the sim run more smoothly.💁‍♂️

Modern cpu's switched to TSC timers a few years back. Probably no harm in disabling HPET if you see a difference.

My pc became more responsive after disabling HPET. It's an old trick, But we can't remember everything.
