RTX 4090 and i9 13900K : low GPU and CPU usage since last update?

Hello,

I have a PC with an Intel i9 13900K, RTX 4090 FE, 32 Gb of RAM and Samsung 990 Pro 2 Tb.

Since some times (maybe the last update) I never head my fans kick in when I load a flight.

Look at the Xbox Game Bar in the performance Tab and my RTX 4090 never go above 30% of usage and my CPU never beyond 5%.

Am I the only one having this issue or is there an issue with the last update
