Well, it took quite a hit if we're honest...it's extremely blurry and textures are very low res....for my taste, it's an eyesore.
But, RDR on PS3 was an eyesore as well...so I guess if you're not bothered with that too much, it's the same TW3.

Personally, I would love to see downporting done some other way, with reworked art style, but that would be too expensive.
