The game has no SLI support right now.
Will the developer add SLI support in the future?

I think I read an article that they were interested in adding things like HDR, so it's a possiblity. I can see why they wouldn't, doesn't seem like a lot of games are using SLI/Xfire

I was able to get SLI working on my quad sli build using the profile I made for another high rez U4 engine game, The Vanishing of Ethan Carter Redux

careful if it doesn't say redux then its the U3 version.


However, my disappointment is that at true native 4k 4096x2160, there are black bars on the sides of the Hellblade game, however other U4 titles have not demonstrated any problem at real 4k and real 8k

can you post your sli profile, please ?

In NVIDIA Inspector, put

0x080040F5 (Daylight, Evolve, Monster Hunter Online Benchmark, Ryse: Son of Rome, Everybody's Gone to the Rapture, Miscreated, Far Cry Primal, Lichdom: Battlemage, Armored Warfare, Prepar3D, Far Cry 4, King of Wushu / Jiu Yang Shen Gong)

to SLI compatibility bits (DX10 ++ DX 11)

-> both cards will work fine with good fps BUT there is some extensive flickering going on!

How I got rid of the flickering (don't know which setting actually does it though), but it works!

put in engine.ini:

[SystemSettings]
r.SceneColorFringeQuality=0
r.Tonemapper.GrainQuantization=0
r.Tonemapper.Quality=0
r.DefaultFeature.AntiAliasing=0

scalability.ini:

[PostProcessQuality@3]
r.MotionBlurQuality=0
r.SceneColorFringeQuality=0

-> the 3 is for VeryHigh settings. So it only works if you are on VeryHigh in the Games Graphics Menu!
