Despite the apparently heavy issues, which I didn’t encounter that much to be honest (FPS drops yeah, and the old-days UE3 texture streaming issues, but well - games aren’t perfect now are they? We should know :)) I must say that I am very impressed by Batman Arkham Knight.
The design in general, the amount of detail, the lighting, the characters (once again), the shaders (ok nvidia helped with the ocean at least, but still) and the dynamic of the environment… This is pretty much what the Samaritan demo once promised. My GPU can’t render the advanced smoke physics/lighting, but the rain alone is pretty much the best I’ve seen so far. I also take my hat off to their seamless design. This truly is unique in open world game design.
All in all, I find it the most stunning Unreal Engine game out there currently and very inspiring to strive even further with the UE4.
