Okay, two questions:
1. Do you use your computer for anything other than gaming? And if so, does the 4K aspect help with like office work or coding? It might, I really don't know. I've never had issues doing office work though on any monitor even going back to the 90s so I'm just curious as to what 4K would add to that.
2. Didn't you have to turn the settings way down on most of the stuff to get it to run decently in 4K? And if that's the case, is medium on 4K better than ultra on 1080p? I'm just curious as to what the trade off is there. Like does a medium 4K look crisper or sharper than an Ultra 1080p on account of more pixels?
#1. Nothing out of the ordinary, TBH. No, I haven't coded in languages like C++ in years (i.e. since college - and I wasn't even that great at that back then, TBH). I have literally way more space on the desktop, web browsers, in programs, & everything pretty much. This alone to me, is a major difference. I had my desktop littered w/ icons and folder shortcuts at 1080p...and now w/ the same assortment, they're barely even taking up part of the left-side of the screen. I constantly have been annoyed by 1080p when switching b/t Windows and always Alt-Tabbing - and now it's easy to have multiple Windows Explorer/My Computer windows going - especially since I seem to be moving games from drive-to-drive more so than ever. These huge-sized games are killin' me here!
#2. For WWE 2K16, nope. Just turned off AA; don't need it. Game runs well anyways. Very well optimized. Even more so than 2K16. With 50-60 frames at 4K when in-ring, it's fine for me.
For Dying Light, yup. Ran crummy at 4K even at Medium, so it's not worth it right now. 1440p does the trick here for me. B/c there's tons of jumping, action & the game feels fast-paced, the console-style of 30FPS is unacceptable at 4K. 1440p at 50-60fps at High fairs well and I'm happy with it for the extra resolution bump.
I often will take a setting (like High, Ultra, etc)...and then go Custom with it by tweaking some things from there. Some things to me, are a waste of frames b/c of the framerate killing they can do (VSync, God Rays, Hair Physics, etc) - and it's often simple enough just to turn something down a bit or something off that are frame-killers to get things to the point where I'm fine + happy with them.
I will most definitely try to play more games at 4K, 1440p, 1200p here - and see how things go.
I do feel more immersed into games now w/ the bigger screen (28'' over 23'' - a world of a difference here) right up in my face + the ability to jump up to other resolutions past 1080p.
EDIT:
How do you get Subnautica running well? It has FPS drops even on a 1080 x.x
Don't own it. Never played it. Can't speak on it.
