So once the day one patch has been applied we're looking at a crisp, native 1080p(stable 30fps) framebuffer on the PS4, backed up by a new custom post-process anti-aliasing solution that works well in suppressing jaggies across much of the scene.
Microsoft's console, there's no special update to boost resolution on the Xbox One game, which renders at 1600x900(stable 30fps) while using an older post-process AA algorithm.
The PC version (1080p/60fps if enough pc gears) provides a similar visual experience to the PS4 release, but with the ability to achieve better image quality over the consoles. The main improvement comes with the inclusion of horizon-based ambient occlusion (HBAO+ in this case), resulting in more defined indirect shadows compared to the simpler SSAO-style effect we see in place on PS4 and Xbox One.
The Wii U version consistently falls 6-10fps behind the 360 and PS3 releases, resulting in a jerky, often uneven update and a profound, unsatisfying reduction in controller response. GamePad's twitchy analogue sticks, the low frame-rate makes frantically running across rooftops and chasing down targets a frustrating affair.
