I have found many of the complaints about the port to be…peculiar. Especially in regards to visuals.
Compared to a LOT of cross gen ports, Arkham Knight isn’t THAT much worse than some others seen, on a visual level. The biggest failing is in the minute to minute performance- being unable to hold 30 fps is what ultimately hurts the port. Hell, the performance of Knight is, at times, atrocious. But I think THAT should be a bigger point of complaint, not the (expected) compromised visuals.
Porting Arkham Knight might have been a bit too ambitious (probably should have just done Origins, which is a fine game), but I think with some performance patches, it should be “viable” as an experience. I think so many commentators are focused on the amazing port jobs, they forget most Switch conversions don’t get that level of care or polish.
All that said, I’m not sure we’re at the point where mobile hardware can handle, even compromised, versions of Knight. But I think Asylum and City should be viable, but everybody wants to tear apart the port of Knight, it seems.
