With the Logitech G Pro X TKL Rapid coming with both Logic's first attempt at rapid trigger and its own SOCD tech, its focus is very clear: This wants to be the cutting edge, even if that edge was dulled by SOCDs' banning in Counter-Strike in the latter half of last year.
Logitech's version of SOCD is called Key Priority, and it effectively allows you to make software shortcuts for how it handles opposite commands.
When you tap the d and a keys together, instead of standing still, it can prioritise the last used key, the first used key, or a specific one each time.
This was banned in Counter-Strike 2, as it was judged to give an unfair advantage to players who didn't know how to strafe effectively, which, I think, is why it isn't really mentioned that much in the keyboard's marketing materials.
What is mentioned, however, is that rapid trigger implementation which, alongside custom actuation, adds so much to Logitech's current lineup.
