Oculus Rift is one of the greatest products ever, and Ima let you finish, but this is even better for multi-monitor gaming.
At least Oculus Rift had identified and addressed the problem of distortion, even though their solution loses image quality. Multi-monitor gaming has been garbage for a decade because everyone seems content with horrific distortion at large FOVs.
I know, it's all a matter of screen placement and eye positioning. That's dumb. I want a wrap-around image. I want to aim a projector at each of three walls and have the result make sense.
If you've tried Fisheye Quake, you know it's hell on your system, and still doesn't look great. If this technique is at all performance, everyone needs to start shipping with support, and they need to start yesterday.
