I don’t have the Piplay setting anywhere near 2.0, only 1.0 usually, with steam on 1.2, and distant views are not too blurry. Of course it is subjective and relative to your expectations but with a good IPD setting you can get nice distant views in my experience.
I am sure it does depend on the game though. Some games have their own SS/resolution settings that can affect things greatly. I suggest trying different games to see. I had an awful blur problem in The Vanishing of Ethan Carter. I realised that the game doesn’t use the Piplay SS, so by raising only steam SS the quality improved greatly. Try multiple games and set Piplay to 1.0, steam to 1.5 or so.
Another thing that may possibly affect clarity is the drivers. Nvidia’s latest drivers aren’t very good for vr performance, I went back to 388.59 and all is good.
