We recently got in touch with various individuals over at Housemarque - with answers compiled by Harry Krueger, Lead Programmer of RESOGUN.
We asked him how the 8GB of GDDR5 RAM and unified architecture of the PS4 is helping the game to run at a slick sixty frames per second and glorious 1080P resolution, to which he replied:
“It is not just helping, it is necessary. With unified architecture we can easily split up our memory usage the way we want and still have fast GPU access to the bits written by CPU. We are using more memory than PS3 has in total just for the flying cubes! The GPU and compute shaders are also being heavily utilized for a lot of things.
“For example, all of the geometry generation (for the cubes and levels), the physics and collisions for the cubes, the particle mayhem you unleash with your Overdrive or Bomb; all of that is being done in compute shaders. There is still plenty of CPU power left over (currently we’re cruising at around 50% CPU usage during gameplay), but with the GPU and compute shaders doing all the fireworks, we do not really even need it,” he added.
