Yeah, you remember when all the game-streaming services failed because they just couldn't actually overcome the latency issues?
And you know that in VR, latency is the thing that makes you feel travel sick and/or have an awful experience? (Good VR sets have such low latency that it's incredible, and this is basically a non-issue, but even a poorly-programmed game can introduce enough latency to have this effect even with perfect hardware).
And that wireless tech - regardless of its implementation - is subject to local radio noise and will "hang up" if there's interference?
Streaming shite to VR is a TERRIBLE idea. That's why they often need proprietary cables to do it, as per the OP.
