When I close my grip on my Rift-S touch controller (last 3 fingers) and hold it for a second or two, then release, there is quite a bit of lag before they open again. The right controller seems worse than the left. My old Rift cv1 did not have any lag. The problem is when you are in a game and try to grip something, then throw it, the lag causes it to either stick to your hand or weakly go offline. Hopefully this is just another tracking issue that will soon be fixed with an update. Tracking lag and screen flashing are my only complaints with my Rift-S so far.
