A slight idle power consumption increase/regression recently

I’ve noticed that for the past three to four months of NVIDIA Linux driver releases the idle power consumption has slightly increased from 8W to around 11W for my GTX 1660 Ti. It’s not bothering me too much considering I’ve got a desktop PC but it still would be great to get back to the previous numbers/behavior because under Windows 10 it’s also around 8W.

System information:

GPU: GTX 1660 Ti
CPU: Ryzen 5800X
OS: Fedora 35
Kernel: 5.14.13 vanilla
DE: XFCE with no compositing

X.org’s configuration:

Section "Device"
    Identifier  "Videocard0"
    Driver      "nvidia"
    VendorName  "NVIDIA"
    BoardName   "NVIDIA Corporation TU116 [GeForce GTX 1660 Ti] (rev a1)"
    Option      "Coolbits" "28"
    Option      "metamodes" "nvidia-auto-select +0+0 {ForceCompositionPipeline=On, ForceFullCompositionPipeline=On}"
    Option      "UseNvKmsCompositionPipeline" "Off"

Has anyone paid attention to this? I know it because I see it on the screen at all times.
