Occasional "major" CPU spikes

I completely agree with you.
Something seems to be causing excessive CPU usage in FS2020.
I definitely don’t think it’s a hardware issue.
I waited for it to be resolved in SU15, but it didn’t. I spent a lot of time trying to find the cause, but couldn’t find it.
It’s not a problem with the aircraft or a problem with the scenery.
Excessive CPU usage in FS2020 clearly appears to be a problem with FS2020 itself. The CPU usage rate, which was 35-45% (FS2020’s usage rate is 25-35%), suddenly soars to 100% and this phenomenon continues for a while. Then it returns to the normal range again.
So I’m always anxious.
I’m afraid there may be a problem with the CPU. It will definitely affect the lifespan of the CPU.
Sorry for my bad English.
