It's not on idle right now, that's with 10 different softwares opened, I work with 3d stuff, I know the laptop is currently using more than what's displayed (the 15gb), It's probably well over 20 or 30 so I think it's displaying incorrect values here, because the laptop isn't slowing down as it used to with 16gb

I have 32GB and I rarely see more than 16GB being used at once so it honestly seems like your usage is fine, as long as all your programs are running well with no slow down or crashing then your system is using all the memory it needs to
