This is because certain features (like haptic feedback and adaptive triggers), like the triggers, work by exposing them as an audio device to the host system, which isn’t functional over Bluetooth (the reason I heard is that Bluetooth just doesn’t have the latency for that, if there are third party projects that have found a way around that then great!).

All normal controller features work fine, you just can’t use some of the PS5 exclusive stuff. I don’t know of any games, including PS5 games ported to PC, that absolutely require the wired gestures.

Note this applies to all PCs, regardless of OS.
