MSFS -) Huge CPU Temperature Spikes (not on ground)

[aceridgey 330]

Hi all,

Really struggling with this issue ;

Extreme CPU usage at cruise altitude - User Support Hub / Hardware & Peripherals - Microsoft Flight Simulator Forums

(AMD7800X3d) Spikes in CPU usage increase TDIE Temperatures - User Support Hub / Hardware & Peripherals - Microsoft Flight Simulator Forums

 

MSFS support are not being particularly helpful so here I am :).

I've got the same processor as you and experienced exactly this on a flight over Germany to Greece the other day at high altitude. Performance was so bad on the way back that I just quit the sim. I've got a PC, and hadn't optimised anything at that point.

The two changes I made were to disable virtualisation and also to disable hyperthreading (SMT? in AMD parlance) in the BIOS. I've not flown the same route again yet, and have always tried to avoid Germany in general because I found performance to be pretty terrible there on my old system), but every other flight since in different regions has been great, with no temperature spikes anymore and no stuttering either.

I hope that's useful for you in some way!

I wonder if disabling virtualisation is the key. MSFS support is not very helpful, but i've seen a number of people with this issue.

 

It's 100% an issue with MSFS as no other titles have anything like this,
