Today Q-Games Engine Technology Director James McLaren held a presentation at CEDEC in Japan, showcasing the innovative tech behind the upcoming PS4 exclusive The Tomorrow Children.
Among many interesting elements McLaren showcased how the PS4’s Async Compute technology allows the studio to save over five milliseconds in an effects-heavy frame.
The PS4’s asynchronous compute feature is used heavily in The Tomorrow Children, and most of the screen space/voxel space work is done in compute shaders. There are three async compute queues set up in addition to the engine’s graphics pipeline. On a heavy scene async compute saves about 5 ms in each 33 ms frame.
Below you can see the RTTV capture of the same frame, a fairly heavy one. On top you can see it using just the graphics pipeline, on the bottom with the addition of async compute. Everything is more overlapped and takes about five to six milliseconds less to render.
So, anyway, if you aren’t looking at using Async Compute on PS4 yet, YOU SHOULD!
