On my cv1 there was an ipd tool in home where you would adjust the ipd until the green lines of the ipd tool were clear as it will get. Mine was clearest at 63. On the rift s in home settings u do ipd but no matter what setting it always looks the same. If it's at 63 or 70 it looks the same. There is no cv1 type green line type tool to see when its clear or blurry to get your settings right. I tried to see if the letters on the same settings screen would get blurry if I moved the software numbers way up to 72 or down to 58. Still all looks the same. Any opinions?
