Oculus Rift

Though the Oculus Rift headset is indeed a technological marvel (and one step closer to realizing gamers' virtual reality fantasies), it isn't without its share of problems in its current state. The Oculus Rift headset only displays 1080p and combined with many games' use of motion sickness, causes nausea. 

According to Oculus VR CEO Brendan Iribe, the consumer version of the headset (which still hasn't received an official release date) won't have such problems. Iribe explained that increasing the resolution of the display and decreasing the latency of motion in games will help with these issues, promising that "It is going to work. It's going to work for everybody."  

This means that the Rift will eventually come packed with a 4K display, resulting in alleviating any induced nausea as a result of the 1080p display.  

"You can't imagine what it's going to look like when it's 4K,” Iribe stated. "It's not now, but it's coming."
