The equivalent of the nVidia 3D vision technology for PC will be introduced on Play Station 3 consoles as well. Along with the 3D content offered by the Blu-Ray disks, a series of games will be displayed with stereoscopic signal. Unfortunately, the people over at Sony decided that all titles to be limited at the 720p resolution when displaying stereoscopic images. The reason is very easy to guess by people with knowledge in this area.
The game needs to run with at least 60 frames per second to be able to be displayed at least for each eye. If on the PC this limitation can be solved without reducing the resolution by adding a video card in SLI configuration with the already installed one, in the case of Play Station 3 this option does not exist.
The Play Station 3 console has a fixed video card and programmers need to work with limited graphical performance. A good chuck of latest generation games run at 1080p resolution, however with a framerate that usually goes below 30 frames per second.
Reducing the visual effects is also an option, however it will be very visible for players. Sony thinks that only a few will notice the difference from 1080p to 720p. This actually is true for screens with 50” display,if you look at them from a good distance. Practically, players sit close to the TV the game is being played on.
