As suspected, Uncharted 4: A Thief's End's single-player mode will not run at 60fps.

During a Q&A session today following an extended gameplay demo, Naughty Dog developers confirmed that, after much deliberation, it was decided that the campaign will run in 1080p at a locked 30fps.

"We had a really long, involved conversation about it with all the leads and directors," co-lead designer Anthony Newman said. "We just realized that, for the game we wanted to make, to make the best game possible, [30fps] was just something that we had to do."

Kurt Margenau, Uncharted 4's other co-lead designer added, "We want to have the best-looking game. To have it be consistent, locked 30fps." Newman jumped back in: "To me, a locked 30fps is way better than a variable 60fps."

He went on to list more reasons why 60fps could be problematic.

"If we wanted to hit a locked 60fps, there's a lot of optimizations in the environments that would have to happen," Newman explained. "This would make each level take longer to make. The same amount of geometry would take longer to make because it would have to be so heavily optimized. And so that could end up having story repercussions. 'We want to have this scene, but we don't have the time to make the environment.' It's a feature, like any other, and you have to consider it against everything else."

Uncharted 4's multiplayer mode, however, is targeting 60fps. This is the same figure that Naughty Dog said it was aiming for back at E3.

A beta for Uncharted 4's multiplayer mode will be available prior to the game's release next year. You can guarantee yourself a spot in the beta by purchasing the Uncharted: Nathan Drake Collection, which launches in October for PlayStation 4.

Naughty Dog also announced today that Uncharted 4 will have a Photo Mode. Additional details about this feature will be announced later.
