I have a ryzen 9 7950x and temperatures never overheat when I play a game while streaming or recording I have my task bar pulled up to see My performance my cpu usage with spike and down constantly what ever I have open at the moment it spikes up I keep everything updated to drivers and windows I never fixed the problem.
Can you try to be more clear? I'm not even sure what the problem is.
The CPU spikes up and down in what?
Usage? Frequency? Power Draw?
Only in gaming? Idling? Under load?
