Personally, I think its mediocre at best. The fact the full game can be ported seems to sidetrack from the real conversation. I guess the standard is so low nowadays that the fact that we can get the port at all is excuse enough for whatever technical shortcomings said port has.
I find what Saber managed to do to be quite remarkable...the problem is, the way they had to do it (without redoing complete art, like ports were done in the old days) produces version that is so blurry and cutdown that it looks quite terrible.
And this is just days after a great port that Sniper Elite 3 is - albeit game that is originally more of 7th gen tech game, but precisely because of that, with less things that needed to be cut down, looks vastly superior to TW3 port.
