Watch Dogs uses a custom anti-aliasing solution on Xbox One and PS4 and frame rate is "very important" to the team, according to its lead programmer.
Ubisoft's Francis Bolvin detailed the technology behind Watch Dogs' new-gen visuals in an interview with GamingBolt.
"Watch_Dogs uses the same post-process anti-aliasing solution on both Xbox One and PS4," Bolvin said. "Each frame, a custom [subpixel morphological anti-aliasing] filter is applied on the image. On top of that, we smooth the image even more by using a temporal solution; that is, by re-projecting each pixel to its position in the previous frame and by letting each go through a set of heuristics tailored for the game, we're able to further reduce visible aliasing."
This process differs from the PC version, which uses Nvidia's TXAA, or temporal anti-aliasing. Bolvin said that visual quality is important, but running the game at a good frame rate is key for any system.
"Frame rate is very important to the gameplay, to the controls," Bolvin said. "It's not something you want to compromise on."
