Beware, faint of heart turn back now. John totally geeks out on new ideas he has for refresh rate times, advanced display drivers and head-tracking/render optimization.
He is one of, if not the greatest game engine programmer in history. We should feel very lucky to have John leave ID to join the Oculus team and devote his focus to VR and the Rift headset. I doubt anyone alive today is better skilled and experienced to advance the new industry than Mr Carmack can.
Here is a priceless reaction from a guy experiencing “remote presence” for the first time during a simple miniature roller-coaster demo using the Oculus Rift. Notice how he ducks to avoid obstacles.
What’s happening is your body believes the input so much, that it refuses your own abstract understanding that you are really not moving and believes you are in danger. It forces you to duck using the fight or flight response. This is why people like Mark Zuckerburg have invested billions, he realizes just how ground-breaking this technology will be moving forward.
