To be honest, I find a remarkable resoultion difference between Gear vr and my rift. The clarity is too much better, mybe due to the high ppi on galasxy s9, and the better lenses on the gear vr. The sweet spot is way bigger, and the ipd setting is for me atleast perfect. I dont see any line in the middle on gear vr, whilst its always there on rift no matter how I change the ipd..
Next step is to combine vive wands and basestations with gear vr..... of course while waiting for pimax 8k
