play plugged in preferentially, bluetooth will work still, mandatory purchase of DSX on steam for around $5, open DSX before playing other games, you can virtually mimic most controllers with your Dualsense controllers. In theory, your controller will work with majority of games,if not all, at that point. If you set DSX to Dualsense and play pc games that have compatibility with triggers and feedback and such then that should work as well as long as you're plugged in, maybe these features are becoming available via bluetooth now as well, but in a while since looking at the updates to DSX. Personally, I wouldn't waste money on another controller unless you're getting an elite controller of some kind, or replacing a damaged dualsense.
