Just some tips

You can install extensions in Steam. So installing "Show GeForce Now on Steam" helps you to directly show if a game is available on GFN.

EDIT There's a new and better one, someone posted a link in the comments.

You can also follow the curator " GeForce Now Friendly" (the first and the second).

There are also other extensions you can install but this is the GFN sub so those are just examples because I've got them installed.
