New Mod Successfully Brings 'Doom 3' to Virtual Reality. SweViver walks and runs about naturally using only the Vive controller's touchpad, and he says multiple times that the "perfect" 90 frames per second keeps him from suffering motion sickness. Beyond that, the video shows him jumping and using the mod's impressive hand-tracking to handle his gun and flashlight separately as they float before him in place of the controllers in his hands. At one point, he even whips out virtual fists that let him pummel things with the controllers' left and right triggers.
