There's no buttons to turn off the  motionsync in viper v2 and v3 pro which it makes me so sad that I have to forever using it. It feels so bad when you turn on the motion sync especially the long ttk fps. You can always feel -2ms to track the movement I can tell. Hope you guys can design a simple button for the sync in the synapse4 . Every other 3395 and 3950 does it. Like sorav2 or lamzu. It's kinda disappointed.
