I still remember playing Doom and thinking it was just incredible at the time, but to fast-forward to now and think our smartphones have superior resolutions to the once superior 320x240 is scary.
Well, a Deviant Art user going by the name Elemental79 has converted a simple 320x240 pixel screenshot from Doom, to an absolutely gorgeous 9600x7211. This includes textures, lighting and 3D effects, all done within Photoshop. Elemental79 has said that:
Each frame represents ten seconds of work. The image spans across 7 PSD files at a resolution of 9600x7211 pixels. The project took 35 hours to complete over the course of 8 days.
I wouldn't mind playing the game if it were like this, just give me Oculus' Rift VR goggles and I wouldn't come out of my office ever again.
