High CPU load and stutters over certain locations

Hi all - I’ve been having an issue almost every flight that occurs when I look in a certain direction where the fps will drop dramatically, accompanied with audio popping and stuttering. CPU usage will spike to 75% or above, until I look in a different direction. This will continue until I’ve flown past the area causing it. A lot of times it’s when approaching small airports.

I can’t figure out why it’s happening, as there doesn’t seem to be any rhyme or reason. It’s not happening at big airports or graphically intense areas, but seemingly at random. I’ve experimented with different graphics settings and nothing seems to remedy.

Any ideas would be helpful.

i9 14700KH
RTX 4080 Super
32 GB Ram

Normally get 110-120 fps before the big drops.

Are you reporting for msfs-2020 or msfs-2024 ?

This sounds like the issue some have been experiencing with the Fauna setting. Try a lower setting, possibly even off, to see if you can isolate it to that.

Just a quick update -

Removed community folder
Cleared all Nvidia cache
Cleared all FS2024 cache
Used DLSS switcher to switch to latest

So far, so good. I’ve seen the fauna tip in another post - will try if stutters come back.

I have huge stutters once my rolling cache is full, try deleting it and resetting it. Works for me!

Struggled with these audio pops. Always get them in the fenix a320 eastbound out of Klax. Tried everything. Then I disabled smt on my 9800x3d and though my cpu still spikes in the same location, no stutters or audio pops. I have tested and can turn on or off the pops and stutters by turning on or off smt.

I have consistently encountered audio and visual stutter arriving EGLL from the north/north-west, I believe A330Driver also encounter this problem which limited him from streaming. If anyone managed to sort that out I’d love to know how, I’ve tried multiple things with MSI afterburner off, HAGS off, BIOS, SVM, fTPM, everything, but it’s still present.
