Everyone is going 3D; from Movies, to TV to personal gaming systems. It seems like the 3D craze is back. Many of these systems are quite good, others not so good and a few almost funny. One of the funny ones is the latest from Sony. They were talking up their 3D for the PS3 and finally had to admit that it was going to come at a price.
This price will not just be in money but there will also be some loss of detail and even the need to upscale to get to proper resolutions. It seems that to get 2D games to run 3D Sony broke the 1080 stream into two 720 streams at 30Hz. This is not exactly what you would have expected (1080p at 120Hz) and for games that already run at 720p they have to upscale to get the proper video information.
Of course you have a different story if the game is coded to run Sony's 3D natively.
