Resogun PS4 uses Sony’s GPU to offload the visual grunt work, CPU mostly focused on gameplay

Resogun PS4 developer Housemarque has discussed the shooter’s technical nature, and has confirmed that it offloads much of the visual calculations to the console’s GPU, leaving the CPU free to focus on handling gameplay.

The studio explained how it all worked at a Sony event in New York, during with the PS4 Interface was detailed in a new video. Watch it through the link.

Speaking with Polygon at the event, lead programmer Harry Krueger explained that to ensure the game’s “tens of thousands” of particles could flow smoothly, the team applied the behavioural effect calculations to the PS4′s GPU.

He added, “Basically, most of the cubes, the individual voxels, all of that stuff is basically done on the GPU, and that offloads a tremendous workload off the CPU that’s left to just focus on gameplay.”

Sony touched on this capability earlier this year, stating that the PS4′s 18 compute units would be capable of sharing workload in this manner. Krueger added, “At Housemarque, we’ve always been a very technically proficient company because we have a lot of people from the demo scene. A lot of people just naturally like tinkering with this kind of stuff, you know? So, it just came naturally that we just started looking at GPU compute and using it as much as possible in order to get all this stuff happening.

“If we had to do all of that on the CPU, the game would still kind of be a similar experience, but it would have a lot less of this going on. It would be a lot less dynamic, a lot less fluid. Basically, the experience would not be the same.”

Stay tuned for our own Resogun interview with Housemarque on Thursday.

PS4 is out November 15 and November 22 in the US and UK/Europe respectively.

    The way this is written kind of confuses what is actually happening, to clarify what they are saying is that the physics calculations are offloaded on to the GPU, rather than the visual representations of the physics effects. Like, what you see with physics effects aren’t the most computationally expensive aspect of physics, it’s the actual calculation aspect of the physics, calculating what does what, and how the particles interact with other particles and the surroundings.

    So what he is talking about that they have offloaded the behavior of those effects on to the GPU, as the GPU would have been processing the visual representation of that behavior whether the physics were being calculated on the CPU or the GPU.

    What #2 said. Otherwise we could even say the audio chip is responsible for the sound and music…

    If you have a lack of understanding then it’s best to keep quiet rather than shout about it.
