I mean, the screen quality would. The games would look better.
It's a 720p screen roughly the same size as the 800p screen used in the first Rift DK1, the quality of games on the rift DK1 no matter how powerful your pc, was terrible because the screen door effect present from the low resolution screen was absolutely shocking.
Yeah, but no one has made a mobile VR headset using a "big" 6.2 in. screen before. You would not have to magnify it so much. It might help a little.
Categorically wrong, hundreds of VR googles intended to be used with smartphones have been made, with support for mobile phones with screen sizes between 4 and 7 inches.
And many, many, many more.
