| Slimebeast said: I am trying to draw conclusions. Good. In the KZ2 (or KZ3) example. Lets say the 2-d version is 30fps. WIll the end result be that the PS3 outputs 30 frames per second (every other frame is meant for separate eyes, but that's something for the shutter glasses to sort out)? And the gamer will experience it as 15 frames per second since every other frame is blocked for one eye? Now Disolutiude mentioned the framebuffer and double resolution in the 3-D version and that could explain why he talked about 8 frames per second per eye, but in my eyes that's practically the same thing because the end result is the same - the viewer gets his framerate halved due to 3-D. |
In simplest terms its like this.
Killzone 3 (2D) = 1280 by 720 resolution at 30 frames per second.
Killzone 3 (3D) = 640 by 720 resolution at 30 frames per second each eye. So half the resolution but twice as often considering you need one unique frame per eye.
So the experienced framerate of each is the same, its just that in the case of 3D imagine that its outputting the image on two seperate TVs each running at 30 frames per second. So the TV on the left is the left eye and it has a slightly different view to the TV on the right for your right eye.
How this works with shutter glasses is like this:
Eye 1: Frame - Blank - Frame - Blank - Frame - Blank - Frame - Blank
Eye 2: Blank - Frame - Blank - Frame - Blank - Frame - Blank - Frame
Where blank = no light allowed due to the shutters being closed and Frame = whatever needs to be displayed. It works the same way as a CFL light bulb does, it doesn't offer continous light but an illusion of it which gives you the 3D effect.
Tease.
