Sony PlayStation certifies VR games if they submerge 60fps




Developers who want to release games for the PlayStation VR, must ensure that the frame rate will amount to a constant 60fps. During the Game Developers Conference, Sony announced that games that do not get it do not get PSVR certificate.

“There is no excuse not to get the frame rate. It may not be lower than 60fps. Never. I can not stress hard enough,” said Chris Norden, senior staff engineer at Sony, at the conference in front of game developers in the presence of Polygon. “If you give us a game which sends drops to 30, 35 or 51, we will probably reject this,” added the representative of Sony to state.

Norden also indicated that Sony is willing to play games from developers and look at ‘technical correctness. Consideration will be given if a game generates for example nausea, where problems occur with the frame rate and whether there are glitches occur when tracking the player. This process should take place early in the development phase, so that development studios can then adjust the constraints to meet the requirements of Sony. Norden says that it is not required Sony to watch the game, but it strongly recommends. To be able to release a game for the PlayStation VR headset Sony will indeed have to approve the game.

PlayStation VR headset displays images with a refresh rate of 90 or 120Hz. To the games that at 60fps on the PlayStation 4 rotate display with 120Hz, which is used Sony reprojection. Is a technique in which an extra frame is calculated on the basis of the previous frame. When interpolation takes into account the movements of the player. This should give the illusion of a higher frame rate. Even in games that run natively at 90fps or 120fps, Sony will use reprojection.

The technique, different from VR glasses for PC. Both the Oculus Rift as HTC Vive have a refresh rate of 90Hz, but games must thereby actually run on the frame rate for optimum experience. Conversely, these headsets do not use interpolation.

Sony made ​​during the GDC known that the PlayStation VR goggles comes on the market in October and 399 euros will cost. To play with the headset is also requires a PlayStation Camera, which costs about 60 euros.
