x15 R1, seems to not be using Nvidia GPU

Hi. I recently noticed a downgrade on perfomance. TO be honest I cant say exactly when happened. I fly a fly sim called DCS. It used to run very nice and I noticed now a drop on perfomance. And what I noticed now is: when I press CTRL ALT DEL and see the sistem perfomance, I can see integrated GPU activity going and down, and the nvidia GPU activity it is always CERO. On contrast I can see the memory of the nvidia card being used, all of it.
I f I bring the nidia perfomance monitor, I can also see a cero activity on the nvidia GPU.
On novidia control panel I have already configured DCS to be run using the nvidia card, I double checked that.
Bios is up to date, nvidia drivers too.
Im running windows 11

Any ideas? Thanks in advance for the help
