After sending my original defective Reverb back, I bought a Rift S and although impressive, I was still constantly tweaking- chasing an image that wasn't possible. After a month I sent the Rift back and ordered a new HP. Huge improvement in clarity. The difference between almost there and definitely good enough for me.
Consequently, I haven't kept up with this thread. Is Steam SS still supposed to be set at 180% (nearest I can get to native res). I seem to remember people were lowering this value to 100%.
