Turns out Nier is more messed up than thought.
Their line of "4k is not officially supported" goes beyond what you'd think. Game's internal resolution is locked to 2k basically. I mean don't even, it's not hard to support arbitrary resolutions. There's already a fix.
Shouldn't expect more I guess considering they couldn't even get a stable 1080p60 out of PS4Pro. (When has Platinum ever gotten a stable 60 out of anything????)
And I can see why too, the game is savage in performance. 1600x900 I've seen usage up to 80% when some alpha effects are going.(Otherwise 50-60%) And this with MSAA and SSAO disabled. At 1080p with 4x or 8xMSAA GPU usage instantly jumps to 100. With 2xMSAA it's in the 70-100% range.
In-engine (1600x900 video files! /face palm)30FPS FMVs couldn't even be bothered to super sample them. So tons of aliasing there in places. Compression is actually not bad so at least there's that. (Mind you these are apparently MPEG-2 videos. Yes you read that.)But that's gonna hurt for anything higher than 1080p and in the future 5 years down the road when the game is stuck with those 1600x900 FMVs. (No game should do this in 2017. It was bad enough with Rising)
What's worse is that all the ones i've seen could clearly be done in engine no problem. (Like one that is literally like 5-10 seconds long that switches back and forth in engine really quick. It's just like really???) There are small scenes done in engine at 60FPS. They just don't have the DoF and stronger Motion blur.
SSAO is awful. Shadow draw distances/Lod distances are really short.
Platinum needs to hire some new people or let someone else port their games. (In this case however, Square Enix would probably **** it up more themselves.)
And with all the scaling issues, it's like they only tested this game at 1080p. And only 1080p. The game, which runs at 1600x900 on standard Ps4, doesn't even run properly in 1600x900 full screen.
How, does this **** make it past testers? I doubt it does, I bet management just says "That's shippable. Maybe we'll fix it if enough people complain!"
And this is Square Enix. They do not fix. ANYTHING. EVER.

Lawd have mercy.
Anywho, you CAN enhance the game with SGSSAA. However, edge quality becomes worse than standard in game MSAA and most fine specular issues and other stuff are just missed.
Ex: 4xSGSSAA

MFAA doesn't work properly either. Just fuzzy edges that look worse.
