PrefersNonDefaultGPU is specified as follows in the Specification: If true, the application prefers to be run on a more powerful discrete GPU if available, which we describe as “a GPU other than the default one” in this spec to avoid the need to define what a discrete GPU is and in which cases it might be considered more powerful than the default GPU. This key is only a hint and support might not be present depending on the implementation. https://specifications.freedesktop.org/desktop-entry/latest/recognized-keys.html Checking for a Discrete GPU is a more accurate implementation despite the misleading name.

Uses a discrete GPU when a more powerful GPU is requested using
PrefersNonDefaultGPUhttps://specifications.freedesktop.org/desktop-entry/latest/recognized-keys.html
Gnome and KDE (and Cinnamon) disagree how the check should be
KDE (and Cinnamon) prefer a Default Discrete GPU and otherwise use the first Discrete GPU
GNOME uses the first Non Default Discrete GPU and otherwise any Discrete GPU
I'll leave deciding this to someone else though I think the way KDE did it is best for usability.
