On the PS4 Pro, adaptive resolution feature plays a significant role then. After pixel counting a huge number of shots, we came across a wide resolution variation in each mode. While using the action mode, Nioh presents resolutions including a full 1080p, 1728x972, 1665x940, 1472x828 and even 1280x720 in rare instances. In comparison, the movie mode sees a variation in resolution ranging from 2160p to 1800p down to 1440p. The variable movie mode even exhibits drops to 2304x1296 at points. This option also enables slightly higher resolution shadow maps, while the increased pixel count helps enhance texture filtering.
The same technique is used on the standard PlayStation 4 console as well. When using the action mode, Nioh spends a lot of time at 720p mark but regularly jumps up to higher resolutions, such as 1600x900 or 1728x972. You can expect these higher resolutions when pointing the camera towards less complex scenery but on average, image quality is visibly less refined on the base system. For those demanding improved image quality, movie mode bumps the game up to 1080p at 30 frames per second. We still spotted the odd drop in image quality now and then but it's 99 per cent locked at 1080p using this option.
