List of 4k-able games with a GTX970.

[KA*sino]

To start off I would like your help. Other 970 owners, please help me with games and I will update the list. Just thought it would be fun to collect all this data in 1 spot. Also, to get help finding games that can take advantage of my TV =) Sure, many can be on the older side but dont forget they get a proper visual boost that can make them more relevant again. =) (Will however not go too far back and never below medium settings)

The ones I can think of right now that I own and have played in 2160p myself are:

Alien Isolation
Amnesia
Batman Arkham Asylum
Bioshock (Entire series)
Bulletstorm
Call of Juarez: Gunslinger
CoD MWF 1, 2, 3, 4 (HD Remaster included)
DMC
Darksiders: Warmastered edition
Dead Space (Entire series)
Deadfall Adventures
Deadlight
Deadpool
Deus Ex: Human Revolution
F.E.A.R (entire series)
Far Cry 3 (DX9)
Fifa 17
Furi
Hotline Miami ;)

Not all these titles are maxed out but can achieve 60fps smooth in one way or another paired with a GTX 970. (Otherwise specified as 30+ title)
My total PC specs are:
i7 4790k at stock speeds
GTX 970 custom water cooled Gigabyte windforce

All packed in to a Corsair Air 540 case with a few other goodies (who cares, right?) =D

Thx guys. Your additions are on the list. Digital foundries has started a 4k on a budget series. Started off with the Crysis trilogy.

Shadow of Mordor actually works pretty fine at 4k 30 fps on ultra (gtx 1060 3 gb)

I shall test on my 970. Tho I have a strong recollection I turned it down to 1080 for a stable 60 =)
Edit: I tested 4k at medium settings and hover around 40-50fps in fighscenes and 50-55 just looking at the landscape. So yeah, actually 4able on a 970 for those who can stand sub 60 fps =) (depends on the game in my case, should perhaps add a 30fps section as well.)

Have Vanquish up and running now in 2160p as well. =) Some concessions were made but the important stuff like shadows and Ani sits at high & x16. The V-sync implementation is awful so I turned it off and put on adaptive in nvidia cp. Would say its an 55 avg. Mostly 60 with some dips. =)
