The official Link cable is an (overpriced) optical cable. Theoretically that is supposed to make it better over longer distances, but actually a decent 5m USB3 cable works just as well – for a third or so of the price.
If you want to be on the safe side, buy one that has been tested for VR/Link. Search for ‘KIWI design USB C Link Cable’ e.g. on Amazon. Comes with a built in signal amplifier.
If you happen to have a good Wi-Fi 6 router (ideally with your PC connected via a LAN cable), cable-less AirLink is also a viable option. How well that works heavily depends on the Wi-Fi connection’s quality though, so for the least possible amount of compression artifacts a cable is the safer method.
I didn’t think to ask, does the quest 2 automatically detect the link cable or does it require special steps?! I know there are some VR units out there that can be tricky to get working with a PC connection. Thanks…
When you plug the Quest into the PC it asks whether you want to enable Link or not. You can also enable Link in the settings. It’s pretty straight forward. One more step than plugging in a ‘true’ PCVR headset, but nothing to worry about.
