+      # the following is from @tlater:matrix.tlater.net (Lix Off Topic, 2026-06-24)
+      # `powerManagement.enable` maps to this set of NVIDIA driver features: https://download.nvidia.com/XFree86/Linux-x86_64/610.43.02/README/powermanagement.html
+      # You can read through those docs yourself, but tl;dr: modern GPUs have more memory than can normally be stored on suspend, so they need a workaround.
+      # The modern open source drivers can use some cool kernel features that were behind the GPL lock beforehand to achieve that, the proprietary drivers are stuck with a hack. But basically, you always want to enable that option on NixOS.
+      # The `powermanagement.finegrained` stuff on the other hand has to do with multi-GPU setups. The two options should really not be grouped together like this.
 
       # Use the NVidia open source kernel module (not to be confused with the
       # independent third-party "nouveau" open source driver).
