If you follow id Software's John Carmack on Twitter (and can understand even half of what he's talking about), chances are you're aware he's beehn playing around with Head Mounted Displays (HMDs) and, specifically, has been working on getting Doom up and running with the tech.

We reported a little earlier that the freshly announced Doom 3: BFG Edition was also made ready for 3D TVs "and head mounted displays". This is key to Carmack's project where recently members from website The Verge made a trek down to id's Dallas-based studio to have a closer look at Carmack's toying with modern virtual reality.

Essentially, the Oculus Rift contains a 1280 x 800 screen split in two — 640 x 800 for each eye — with an image that really needs to be seen to be believed. While the images themselves are relatively low-resolution, the immersion factor is pretty fantastic. That's due to the Rift's 90 degree field-of-view, something you won't find in most other HMD's (including Sony's recently-launched 3D head mounted display, which Carmack praised for its high quality and relatively low price point).

The site features a video of journalist, Ross Miller, using the HMD, as well as more in-depth analysis of the tech, but everything is sounding positive for VR's return to glory (it all but dropped off the planet in the late 80s and early 90s). Their only concerns come in the low-resolution display, but concede that over time this is likely a component that will update.
