E3 2013 - Oculus VR is kicking off their E3 experience with a major upgrade to the Oculus Rift, which now is able to display the virtual-reality world in full 1080p glory. The company has upgraded the virtual-reality headset not by creating a custom display but switching out the original non-HD display developer units received to an off-the-shelf 1080p HD display used in cell phones.
Early reports are stating that the new display makes a huge difference and the immersive world created actually feels like you're really there. The 1080p screen is actually split in half and each eye sees a 960x1080 portrait display.
Word is that the company was worried about how the switch from landscape to portrait mode might affect games but he said that there have been no issues reported. Additionally they have not noticed any issues in with the existing games created by the 10,000 developers who now have Oculus Rift development kits.
