PS4 SDK 2.0 Revealed: Includes Lots of Interesting New Tech and Features Game Developers Can Use
During a presentation at CEDEC in Japan, Sony Computer Entertainment revealed the features of the PS4 SDK 2.0, released to support the features of the console’s 2.0 firmware and to provide exciting new tech that game developers can use.
The optimized Physics simulation libraries included in the SDK have also been detailed. A combination of GPU and CPU physical simulations is provided. The CPU is used for simulating objects that require a fine control because they’re involved with the game’s logic. The GPU approach allows for large-scale simulations of objects not directly involved with the game’s logic. Both approaches can be used at the same time.
The GPU physics simulation allows for large-scale implementations of rigid bodies, which are normally very costly in processing power. By using the compute shader, it can be made 10 times faster than what a CPU can do.
The demo showcased 1,000 rigid bodies simulated with the CPU, while the GPU managed to achieve a higher performance with 10,000. The demo was also repeated with 4,000 yellow ducks.
The physics simulation also supports vast spaces, allowing the use in open world games, and continuous collision detection, calculating collisions even after the moment of the collision itself.
The GPU of the PS4 is able to perform this kind of task because it can execute general purpose computing. On the other hand, this wasn’t possible for the GPU of the PS3, that had to use the Cell’s SPUs for the purpose. This is enhanced by the shared memory of the PS4, which is all very fast due to the use of GDDR5. This is one of the strong points of the PS4 according to the presenter (Sony Computer Entertainment SVP Technology Platform Yutaka Teiji).
Since the CPU and GPU share the virtual memory space, it’s also possible to easily pass data between the two. This allows to make GPU and CPU physics simulations work together with no issue.
the PSVR speech recognition library has been made available to developer. It’s the same software used by the new and much improved voice recognition system that came with firmware 2.0.The engine recognizes and defines words in a format called “Grammar,” and returns them as input. The SDK also included tools to create new definitions and supports seven different languages.
A lot of more features are added in SDK 2.0 which came with firmware 2.0
