The version tested was 1.02 for PS4 and PS4 Pro.
The PS4 version uses a dynamic resolution with the native resolution ranging from 960x1080 to 1920x1080. The PS4 Pro version also uses a dynamic resolution with the native resolution ranging from 1440x1620 to 2880x1620. The PS4 Pro downsamples from this resolution when outputting at 1080p http://imgur.com/a/FFa95 Both versions also appear to feature a temporal reconstruction technique that improves the resolution for parts of the frame that are similar to previous frames.
