Just to be clear: when I made the thread title "no tracking issues" was directed at the headset, since GB stream was so fucked up.
The moves are a different story. Everyone knows they are old tech and Vive is using newer sensors that rely on IR as opposed to move's "lightbulb" solution. Hence the superiority. I think anyone who tested the moves back then already knows this.
The camera tracks the move controllers, the headset and the PS4 controller dude. It's all based on old tech. Using visible light for motion tracking leads to less accuracy over IR. But it was a cheaper solution for Sony to follow because they had all those controllers sitting around.
I think they would have benefitied from going IR, especially with how nice their HMD is in comparison to the competition.
