You know what, at least let the patches surface before making definitive lists. We all thought AC would be 4k Native too, remember...You remember the thread on Ark Survival, I mean ark survival.?
TitanFall2 = Looks like it will be dynamic, lets wait on that one.
Homefront 2 at 4k = I don't think so, this game is 1440p on Pro.
FFXV = We shall see, Has this been confirmed? I don't see 1800p CB on PRO moving to native 4k on XBONEX, but we shall see..
For Honor = 4k native 30fps is possible with some lower settings, but you must know that a GTX 1060 at 4K does dip below 30fps quite frequently at ultra settings.
Dead Rising 4 = We shall see, maybe with some settings stripped down, but CPU is also a concern with some of these titles as well....FYI, an Oc'd RX 480 runs this just about 30fps with dips below 30fps. Though it runs better on AMD hardware, so that should be a boon to XBONEX, but GPU is hardly the biggest problem for this title..
All in all, we won't know conclusively till any of these patches goes live, but we can also read between the lines on comparable hardware to see what's possible or not. Many devs are saying 4k, but it's not and won't be native in every scenario...
