Hello, I'm reporting an issue with the accessibility of the "Overlay Performance Monitor" setting in the stable (non-Beta) version of the Steam client.
The option to select the "Performance Detail Level" (to view advanced data for CPU, GPU, RAM, etc.) does not appear in the tab, nor does the option to display the performance monitor, under Settings > In-game in the stable version of the client.

In the "Overlay Performance Monitor" section, the settings jump directly from "Enable/Disable Key(s)..." to "Screenshots"
