About the Sony PlayStation VR has been buzzing with a question: This helmet uses the PlayStation 4 driver, and the performance of the PS4 is doubted by many people to drive a good VR experience until the media discovered that the original PSVR helmet is not directly connected to the PS4, but in the middle A black box was added and the media called it an "additional processing unit," but Sony has not explained it in detail.
This processing unit "Processing Unit" is considered to be proof of the lack of PS4 performance because it provides additional processing power to improve the FPS of the screen output.
However, Sony's previous media coverage at the GDC 2016 was clarified. According to RoadToVR, in the "PlayStation VR: Development and Innovations" forum yesterday, Sony senior engineer Chris Norden explained what the box is for:
What is it for?
3D audio processing
Display multiple screens, including mirror mode, split screen mode
Display PS4 Software Interface in Cinema Mode
What is it not for?
Additional GPU processing power
Additional CPU processing power
PS4 "Extensions" or "Upgrades"
Allow developers to use in any way
Norden said that many game and technology media have reported the box as PS4's auxiliary rendering device. "The PS4 is fully capable of 120Hz output," he said.
Of course, this misunderstanding caused Sony to have certain responsibilities. The official name of this part is "Processing Unit."
Norden further explained that 120Hz rendering is done by the PS4, including distortion processing. This “processing unit†is actually a distorted picture that will be output to the VR helmet, reproducing an undistorted picture that is output to the TV screen so that the picture appearing in the helmet can be displayed to the TV in an undistorted manner. On the screen, this is mirror mode.
This part also enables split-screen mode, which is to display completely different pictures and audio on the TV than in the PSVR. This allows developers to implement asynchronous game design. This function is the basis of Sony's Palyroom VR. This VR body game includes several mini games. Through this function, non-VR players and VR players can play together or cooperate.
So according to Norden's explanation, Sony's addition of this box to PSVR is not to increase extra performance. If this part is removed, the PS4 can completely render the PSVR's required screen.
The reality is that Sony wanted to provide players with a multi-screen experience, so the box was designed. Of course, this box does share the 3D audio processing capabilities for the PS4, but Sony's people explained that it was just because of "why not go" and not because of the PS4's lack of performance.
But PSVR's conversion of 60FPS to 120FPS is not entirely wrong, and Sony offers game developers three options:
60Hz rendering, 120Hz output;
90Hz rendering, 90Hz output;
120Hz rendering, 120Hz output.
In any case, it is not allowed to reduce the frame rate below 60Hz!
