So, I just set up my Vive wands to use with the G2 for some testing in Pistol Whip. Calibration went fine, solid tracking, right where they are supposed to be.
Played a few rounds of the Ember song on normal difficulty with the Vive controller, and ended up with a rank of 942 in the global rankings. So I exit the game, turn off the Vive wands and fire up the G2 controller to see if I do any worse with it. Same song, same difficulty settings. Didn't notice any difference during play, but I did feel like I preferred the trigger of the Vive wand. Made it through to the end on the first try with the G2 controller and with a global rank of 516!!
I'm not saying that the G2 controller is superior in any way, but based on the result, it absolutely didn't hinder my game in any way. It won't be like that with every title, but for most of what I am interested in playing, I won't see much difference between the two. I'll add that I have yet to seriously play the VR Call of Duty wannabes, so that may be a bit of a different case. I suspect that I will pick up Population One when I see a sale, so I'll figure that out at some point.
But testing with the Vive wands seemed to work fine on my end.
