I brought this because the new rtx series cards come with only 1 hdmi port and for some reason my rift hmd keeps showing as usb 2.0, I believe this is due me adding an extra 3m extension to hmd...
I wanted to try the rtx usb c vr link so I brought this hub and although it says nothing about 90hz refresh rate I've not had any problems so far and and my hmd is showing as 3.0 again, I think this is because the usb c provides far more power establishing a more powerful link over longer distances..
