Why does your PS4 controller keep glowing? Because Virtual Reality!
LIke everyone else, you were born into bondage. Into a prison that you cannot taste or see or touch. A prison for your mind. Unfortunately, no one can be told why you can't turn your light off on the DualSohck 4 controller. You'll have to find out what it's for later down the road.
That's totally how that line went, right? Yeah, I thought so.
Anyway, it turns out that "later down the road" is actually today. That really annoying light bar on a DualShock 4 controller is apparently for Project Morpheus.
"That tracking light... it was our department that said we need that on. It was tracking for VR," said Jed Ashforth, Senior Designer at Sony Computer Entertainment Europe told TechRadar.
There you go, mystery solved, Neo.
