I've been experimenting playing Pavlov with the Index instead of the Rift that I've been use to and the results have been quite painful. The knuckles grip feels considerably slow and awkward compared to the simple trigger press of the touch controllers. This matters a lot since the grip is the input required to grip the gun, throw grenades, and interact with the bolt on sniper rifles, which all feel slow and terrible. 

As an aside, the knuckles are large enough to where gripping a handgun with 2 hands is very annoying since the knuckles will just hit each other and block each other. Very disappointing since the increased frame rate and clarity of the headset should've allowed it to be one of the best headsets for VRFPSes. But instead, the knuckles cause it to be a significant downgrade over even a CV1.

The Index works wonderfully well for Vox and racing though.
