Yea. Obviously, I'm not a Vive tech ... I'm just some dude ... but I believe it's going to turn out that the "distance" from the GPU has more to do with the problem than the size of the bus, especially on older motherboards. It's abudantly clear that this tech has been pushed through on "happy path" testing, not vetted the way it should have been against a wide range of real-world scenarios. Incredibly arrogant.
