在E3 2014展会的第一天，泡妞游戏 顽皮狗工作室就给玩家们送上了一份大惊喜——《神秘海域4：盗贼陌路（Uncharted 4: A thief’s end）》的首支预告！然而关于这支预告还引起了不小的争论，如此高清流畅的画面到底是高精建模CG还是即时渲染？今天有网友总结出了可靠消息：《神秘海域4》的预告画面是在一台ps4上游戏内实际实时渲染画面，并且达到了1080p60fps！
"They (Naughty Dog’s Studio Coordinator Rodney Reece and Lead FX Artist Keith Guerrette) confirmed to us that the Uncharted 4 trailer showcased during Sony’s E3 2014 press conference was a part of an actual level in game. Secondly, they also confirmed that the entire trailer was running in real time on the PlayStation 4 and it was all in-engine."
“他们（顽皮狗工作室协调者Rodney Reece 和 首席特效 Keith Guerrette）证实向我们证实了神海4的预告是游戏里实际关卡的一部分。泡妞游戏 其次，也证实了整个预告片是在一台ps4上实时渲染。”
"No, it is definitely real-time, (as my post yesterday might hint) I had one of their devs explicitly confirm to me yesterday that it is running in real time, on a single PS4 and not pre-recorded. "
"Beginning with Uncharted 4, all Naughty Dog games will feature completely in engine, real time, 3D cutscenes (if they even stay cutscenes anymore), a huge performance departure from what they used to ship."
"We've studied the video in a little more depth and have concluded that it's definitely running at native 1080p resolution (as opposed to being rendered at a very high resolution, then scaled down – a process known as super-sampling). Small clipping anomalies, a touch of specular aliasing on Nate's shirt as he sits up, along with some shadow aliasing on his forehead also suggest a real-time render. On the face of it, we're still looking at some pretty incredible anti-aliasing here for a real-time technique on a game running at 60fps, particularly when it comes to the perfect, artefact-free rendering of Nate's hair – but the combination of the low contrast setting, slow camera movement, motion blur and depth of field would work well generally in making aliasing much less of an issue."
