Have you actually used Cardboard? I have the XinGear Headset and a Nexus 6. I haven’t experienced any of this “terrible” experience you’re talking about and I find I actually get better performance, less latency, and better visuals (thanks to the 2k screen obviously) than i do on my DK2. Cardboard obviously won’t run the same on all phones, and it’s to be expected, but I’ve had a flawless experience so far. I’m hands down looking to swap my efforts to Cardboard for the forseeable future, and mostly because not EVERYONE has a Samsung phone.
