Naughty Dog explains why Uncharted 4 will run at 30fps
“We had a really long, involved conversation about it with all the leads and directors,” Newman said. “We just realised that, for the game we wanted to make, to make the best game possible, [30fps] was just something that we had to do.”
Naughty Dog said that while 60fps was possible, it would drag development out and could even impact the overall story.
