PlayStation VR Processing Unit is Not a GPU, is Inaccessible by Developers
With all this hype revolving around PlayStation VR, what with the low price tag it comes with and being the primary reason why AMD is so proud of their increasing market share in the VR world, we are trying to figure out even the smallest details for instance, the PlayStation VR processing unit.
The head mounted display (HMD) comes with a processing unit of its own, although it is basically a display that builds on the power of the PS4. Since Sony has not clarified most of the technicalities yet, people have been confused as to what actually the PU is about.
Let us clarify some of the things. Firstly, the processing unit of the PlayStation VR is in no way a separate GPU and it is also not a CPU for the display.
Chris Norden, one of the engineers who has worked on the virtual reality headset recently took some time out to explain what the thing really is and what it does during their stay at GDC 2016.
He has revealed that unlike what some of us were expecting, developers are not going to be able to access the processing unit for some additional power to improve their games’ graphics.
The reason why PlayStation VR has this processing unit is to take off some burden from the PS4 so that it has enough juice in it to do the hard work and give us 60 FPS. Here’s exactly what it does:
- Object-based 3D audio processing
- Display social screen – Mirroring Mode, Separate Mode
- Displays PS4 system software interface in the Cinematic Mode
So yes, those are some basic and very specific tasks and that is all what the PlayStation VR processing unit will do rather than making the PS4 games look better.
