Halo 2: Anniversary's campaign won't render at full 1080p, 343 has confirmed. Instead, it'll render at 1328x1080 at 60fps. The native resolution of a 1080p display is 1920x1080.
"During development we were really pleased with the way the engine and buffer allowed us to switch instantly between classic and Anniversary engines that are running simultaneously - however that, as you might expect, put a hit on resolution," executive producer Dan Ayoub told IGN, explaining the decision to render at the lower resolution.
"The campaign of Halo 2: Anniversary looked fantastic at 720p with the level of detail and clarity it gave us, but like every other aspect of the game and tech, we wanted to push it further.
"So in the last weeks of development, our teams were able to meet a stretch goal and the campaign of Halo 2: Anniversary now runs 60 fps at a crisp resolution of 1328x1080, which is a significant and meaningful boost in image quality we think fans are really going to appreciate. All of the other games across the entire package of The Master Chief Collection run 60 fps at 1920x1080 native."
Ayoub's comments suggest that 343 has been able to boost the campaign's frame rate significantly during the final period of development. When going hands-on with Halo 2's campaign last month, the game appeared to run at 30fps.
IGN seemed particularly impressed with Halo 4, too, saying that it "looks like it was developed for the Xbox One all along".
Halo: The Master Chief Collection lands exclusively on Xbox One on November 14.
