I just finished up a GDC hands-on demo of Shadow Warrior on the PS4, due sometime this Summer, and the team at Flying Wild Hog confirmed that,
“Yes, it’s running 1080p, 60FPS on PS4″
The studio has stated in the past that they were targeting full resolution and 60FPS, but seeing is believing. The load duration seemed a bit extensive on the build I was privy to playing, but that type of thing will likely be polished out in the next couple of months before release on Sony’s PS4. I didn’t just take the devs word on the frame rate, I played myself, and it’s as buttery as ever. Demon heads were flying all over the place in my short session.
The team also confirmed that they’d be continuing to work with publisher Devolver Digital on the digital release and are looking for partners to publish a physical disc.
