PS4 Masterrace? PlayStation VR requires some extra hardware; a processing box

this box will only handle outputting the TV image (split up and de-warp it for 2D plane) aswell as processing the 3D binaural audio

it won't provide any additional gpu power and it's only connected via HDMI and USB(power), so the data transfer would be waaay to slow to add to graphics processing anyway

Isn't it used to double the frame rate? I thought it was supposed to up the fps to 120, probably by techniques used in tv's nowadays.
Hopefully the specialized box will keep the display lag as low as possible and add final headtracking corrections to the image, so turning your head will have the lowest lag possibe.

no, the PS4 handles the reprojection, from what I read it's a very fast GPGPU task that uses minimal processing time right before the frame is output

and it's very different to how a TV adds in-between frames - a TV takes 2 frames and generates an image based on the differences (it's output before the 2nd of the 2 frames, but obviously has to wait for that 2nd frame to be received and for processing for the generated one to be done -> added lag), reprojection uses the last complete frame and adjusts it based on the latest tracking sensor data
