Here we have an Uncharted 3 Frame Rate Test comparing the Playstation 3 and Playstation 4 versions of the game. The Playstation 3 version tested was version 1.19 of the digital version installed to the hard drive. The Playstation 4 version tested was 1.01 and all footage of this version was captured with camera and object motion blur engaged.
The Playstation 3 version targets 30fps and the Playstation 4 version targets 60fps. These framerate targets extends to both prerendered and real time cutscenes for both versions. Also both versions run using a triple buffered vsync.
In less taxing scenes the PS3 version sticks closely to its 30fps target, but it can dip into the high twenties at times. The PS4 in similar scenes is essentially a locked 60fps with only the occasional dropped frame occurring. During intense actions sequences and scenes with heavy alpha usage the PS3 version can see the frame rate drop into the mid twenties. Corresponding scenes are usually not a problem for the PS4 with the game still sticking closely to the 60fps mark. There does seem to be one scene that consistently causes problems for the PS4 version. That is one part of the London Underground shoot-out near a volumetric light source that causes the frame rate to drop into the high forties to low fifties.
The PS3 version of Uncharted 3 sees a few frame time spikes that can last up to 100ms. These spikes seem to occur when the game is loading in assets, and consequently don't usually occur during scenes requiring quick response from the user. The PS4 version doesn't seem to suffer from any frame time spikes.
Uncharted 3 on the Playstation 3 sees an improvement in one area in relation to Uncharted 2 and that is in regards to frame pacing. Dropped frames in Uncharted 2 on PS3 were often followed up by a 16.7ms frame even though the game targeted 30fps. This could cause the feeling of off putting judder that we don't see here in Uncharted 3.
The Playstation 3 version of Uncharted 3 also has a bug where the game can be plagued by incredibly distracting and frequent frame time spikes. A remedy to this issue is to delete the game's cache.
The Playstation 3 version of Uncharted 3 runs at a native resolution of 1280x720, and the Playstation 4 version runs at a native resolution of 1920x1080.
As always, please watch in HD (preferably 1080p) and 60fps for the best viewing experience.
