Guerrilla Games explains why 'Horizon Forbidden West' works well on the PS4

Guerrilla Games set itself up with an unusual challenge when developing Horizon Forbidden West, which comes out on Friday, February 18th. According to the game’s director and technical director, Guerrilla was well aware of the PS5 and much of its capabilities when it started working on Forbidden West in 2018. But, the company also planned to make the game work on the PS4, a console that turns nine years old this fall.

It’s not unusual for games to be released on both consoles, but Forbidden West is notable for being a particularly massive and detailed game, perhaps the most advanced title yet to come out on the PS5. In a conversation with Engadget, game director Mathijs de Jonge and technical director Michiel van der Leeuw discussed Guerrilla’s process for making sure that the game worked for the PS4 while simultaneously showing off everything the PS5 is capable of.

“We knew it was going to be tricky making something that would make the PlayStation 5 shine, but also be really rewarding for people who have PlayStation 4,” said van der Leeuw. “So we're very happy that we knew about the PS5’s capabilities very early on, because that meant we could plan for how we're going to make this distinction.”

The most immediately obvious difference between the two versions is visual fidelity, with the PS5 targeting 4K resolution (reduced to a checkerboard-upscaled 1800p when running in 60 fps “performance” mode). “From the start, we targeted having higher-fidelity characters, high-fidelity environments, higher-fidelity vegetation, everything, just for the PS5,” van der Leeuw said. “So you'll just see different models for the PS4 version, but with the same sort of atmosphere throughout the game.”
