It just gets more and more confusing lol.
So let's say we have Killzone 2 or 3 and normally the PS3 outputs it at 30fps. In 3-D, will the PS3 output two frames at 15fps and the TV fixes the rest???
|
If KZ2 is running at 30 FPS natively, in 3D it will run at 15 frames per second per eye only if they drop the resolution or do some major optimizing. They have to render 2 images at the same time, hence it won't be running at 30 fps once that is done.
|
But why do they have to drop res? No they don't. It takes the same computational power to output 720p in 30 frames per second as it does to output 720p in 15fps plus 15fps (one to each eye).
|
lol its cause it isn't 720p any more. You are rendering 2 images at the same time. 720pX2.
PS3 uses "frame packing" 3D format.
Here is an image which illustrates what frame packing format looks like. (top one)

Ok, cool Im learning something new! But this sentence u wrote, it just can't be true:
"If KZ2 is running at 30 FPS natively, in 3D it will run at 15 frames per second per eye only if they drop the resolution or do some major optimizing. "
I don't accept that 30fps native becomes 15fps to each eye and with lesser quality.

lol, thats fine, I don't expect you to trust what Im saying if ti doesn't make sense...I guess you need to see it in a real world application.
I don't see why its so hard to understand. 1 single 30 fps video stream becomes 1 single ~15 fps video stream when both images are rendered at the same time. Afterwards the shuttering glasses cut it down even more and make it 8 frames for left eye, 8 frames for right eye.
If PS3 was able to render left frame, right frame in a proper sequence and sync it with the glasses and send that signal to the TV, you wouldn't need a special TV.
