@Flameout777 I was sort of confused about this too when I got my PCL and started using this 'querky' Pimax client 🤪
Here is a Reddit which asks a similar question but note, not only the answer, but also that an official Pimax person is answering so perhaps go there and ask specific questions?
For my part, as I understand it, load up PImax client, then launching a game from My assets or within Steam (or a Desktop Steam icon) I believe will start the game with the setting you have set in the Device Settings -> Games -> Common Settings page. If you want specific settings for a game, select the game from the dropdown box in the same page, check the Enable Program Setting box and set your configuration for that game. You must now start the game using the START button on that page with that game selected.
nullIn summary, starting a game not by selecting it in Games tab then dropdown list will apply the Common Setting (which is the first item in the games list) and starting the game using the Start button on the game in the Games tab with the game selected will start the game with the specific configuration you have set.
This is my understanding and works for me.
There is a Pimax Discord server (link is on the Pimax website) so perhaps get further details from there too, best of luck!
PS. Don't forget to hit the Apply button when you make a change and before you hit the Start button 👍
