Simply so, do valve index controllers work with vive?
Since Valve developed the Vive hardware for HTC, everything Vive related is compatible with Valve tracking. Some hardware is not compatible with 2.0, but in the case of the Index controllers, either will work.
Also Know, can you use HTC Vive controllers with Oculus Rift? Nope, the Vive controllers communicate directly with the headset. Yes it is possible. Just leave the vive on but direct the game to the oculus headset (steamvr trickery).
Similarly one may ask, can you use valve knuckles with HTC Vive?
Best answer: You can use Valve's Knuckles controllers with the Valve Index VR headset as well as with the HTC Vive and Vive Pro. You can also use the Knuckles with your Oculus Rift, but it will require some additional hardware and extra steps to set up.
Are valve index controllers worth it?
Compared to the old Vive wands yes they're worth it, mainly because of the sticks and better support with Oculus games. But they're not mind blowing and for some games you might still prefer the wands.
