The fact that the question can even be asked is an impressive achievement.

The heading is misleading. Alien Isolation on Switch has better anti aliasing becomes the first game to look better on switch.

As they stated in the video resolution isn't everything and doesn't mean inherently better image quality. Also, they explicitly state that it holds close to 1080p most of the time. Not to mention that there is no screen tearing, I could see the argument. 

I'm playing RE5 and RE6 on the Switch. DF pointed out some flaws and I've noticed them (split screen only) but I think they're the best versions of the games. Mainly because of motion control support. They're 7th gen games but they look so good on the Switch!

It seems like a superb port, but I don't get the appeal of the game.

its a good port but ps4 xbox players had this years ago, Apart from a better AA solution theres nothing on it better than the higher console versions in fact in handheld it goes to 500p at times

Definitely looks like one of the best conversions to hit the Switch to date. Feral are on a roll, GRID was also a strong effort, if they keep this up they may join the ranks of Panic Button, QLOC, Saber and Virtuos in the Switch port masters squad.

I don't think it's accurate to say it's a PS3/360 port. It was a crossgen game, and not one where the 7th gen was the baseline and PS4/Xbone just pumped up the res.

The question is... where my physical version, though?

It stays 1080p most of the time, has better AA, no screen tearing and framerate is more consistent. It looks much better than the PS4/XOne versions.

On top of that the Switch version has added very well done gyro controls. Its easily the best version of the game.

If it ever gets a physical version, I might check it out.
