The 500 is the encoding bit rate of the video not the total transfer of data both ways. Plenty of people now suffering with increased stuttering that were fine before since the update has increased the bandwidth. Admittedly I plucked the 2.3 number out the air but I’d imagine there is a good reason why a USB 3 port is required and not a USB 2.
I agree. USB 2 ports support upto 480mbs. There's a big difference between 480mbps and 2.3gbs. I didn't pluck the 2.3 number out of the air. It's what I'm seeing in my test on the oculus software. With people reporting 2.6-3 for the official cable.
What exactly are you arguing? Because you started off saying the unofficial cables are the problem, now you've jumped to usb 2.
And where are the people suffering with stuttering, using a 3rd party cable, that have now switched to the official and are running fine again?
