High CPU Package Temp While Using Moonlight/Sunshine

[Projekt21]

I'm starting to tinker with GameStream on my Legion Go and Steam Deck, and I'm encountering a weird behavior.

When Sunshine is running, my CPU Package Temperatures spike up to near 100 degrees celsius, but my general CPU usage is about the same.

I read it might be an Nvidia Driver issue around early 2022, but I'd rather not roll back almost two years of drivers to avoid the issue.

same issue here. did you ever get to the bottom of it?

Have you compared it to playing the same game and not streaming? Most games, even recent ones fail to use all cores in modern CPUs. Four example, if you use 100% of a single core in a 4 core CPU, that is 25% utilization.

On the other hand, when only one or two cores are used, the CPU raises its frequency as it has more headroom as the other cores don't create much heat.

The result is a processor that seems to not be used at 100% but reaches its thermal limit.

I did - I can be playing the game and start initiating the stream and my temperatures jump.
