I read that as being three separate approaches rather than a single one. I assume the approaches were listed in order of increasing complexity.

I agree that installing software on a reddit users advice can be dodgy and that it is up to you to decide whether your level of annoyance exceeds the risk. All I can say is that you can also do further research on what Core Parking is and how to manage it. A google search for some of the keywords will reveal threads in more reputable places including Microsoft and NVidia forums with the same suggestions and feedback from other users who say they resolved the issue using those suggestions.

You do already have Powercfg.exe on your Windows installation so you can learn the command line switches and make test changes on your machine without installing strange software that offers to make that easier.
