With the image quoted, it puts a lot more emphasis on the face where I do notice more differences.  It may indeed be a difference in resolution.   Or the same resolution just with lower texture resolution and no AA.   Hard to say at this point.

2 more places that really stand out are the sign behind the truck and the front edge of the truck door.  But you have to use the zoomed in images to see them.

If the differences weren't pointed out to me, I wouldn't have noticed.

Neither one looks much like a HD port.

Found some higher resolution pictures - PS3 / Wii U 1080p

Things I noticed on the Wii U version - lower res (you can tell by the sharper textures and better image quality in the PS3 version), no AA. Assets unchanged, AF might have taken a hit too.

So we're probably looking at 720p set internal resolution upscaled (Wii U) vs native 1080p (PS3) with 2xAA.

Not that it matters.. a crappy port is a crappy port.

God look at those shoulders, he barely works on his core.

Wii U owners need to go out and support this awesome franchise so they can get the rest of the series ported, as well as any future releases for the franchise.

Fantastic series.

N64 graphics level and someone still feels proud.
