Sony announces no 1080p resolution for 3D games on PS3; will leave strictly in 720p.

According to Joystiq , PlayStation 3 games in 3D will have their HD resolution capped. While demonstrating the newest version of the system at the Develop Conference,  Sony representative Simon Benson announced that games that run at 1080p resolution will be downscaled in 3D mode -- per eye -- to 720p.  

Speaking to
Joystiq, Benson stated that although the PS3 has the capability of displaying a 1080p image, a  resolution higher than 720p has been restricted because Sony contends that a higher frame rate would impact the quality of viewing.  

Blu-ray movies will retain the 1080p resolution.  Blu-rays run at 24 frames per second, but games run at 60 frames per second -- upping the resolution for games would compromise the smoothness of the frames.  While a "more cinematic game" could be equipped to handle the 1080p resolution at the cost of frames, Sony's current guidelines won't allow users to change settings, Benson said.

A true 1080p image consists of 2M individual pixels, about twice the amount shown in a 720p image. Benson added that even trained computer graphic artist could barely tell the difference between resolutions.

On the Newbies Inc. website, Benson indicated that  that online gamers with a 3D TV may have a competitive advantage over those playing on HD sets.

"It all depends on the gamers to be honest. Initially we were slightly concerned about this because we were thinking, what if it makes it twice as easy or something like that."

He also stated that 3D can have the effect of making games more accessible for inexperienced players.

"I think what’s basically going to happen is that anyone who has stereoscopic 3D televisions and, for example, is playing a driving game, I would imagine you’re likely to find that the accessibility level is higher, that people would generally perform better on their first go. But I think at the high end with the hardcore gamers you’ll still see a [3D] advantage there, potentially, but the margins will be far smaller."

Quite obvious...

To render a stereoscopic image you need to render two images, one for the left eye and one for the right eye, anyone who reads up on technical websites like this will probably know that.

That means that the PS3 would have to render TWO images at 1080p at 60 frames per second, even a beefy PC would struggle doing this.

The Cell may be a powerful chip but that doesn't render the polygons, textures and shaders, that all happens on the GPU which is an Nvidia card which is quite a few generations old now.

Also most people won't notice the difference between 720p and 1080p unless they are sitting so close to the screen that they can see the individual pixels, at which point they have more to worry about than noticing the difference in resolution.

Slightly off-topic, I'm wondering how many games that make use of 2D sprites for effects will look as with the 3D aspect you can tell as there isn't the ability to lock a billboard to a single perspective (following the camera etcetera).

Actually, it has 2 root problems:

First, 3D need double frame rate over tradition 2D display. Say a 1080p60 under 3D mode means two 1080p60 stream for 2 eyes. Together it would be 1080p@ 120Hz. Even fastest PC based GPU today may ran into trouble into rendering such high frame rate!

Second, even though PS3 was over-engineered as a 2006 hardware. The PS3's HDMI 1.3 can handle 3D transmission at 1080i60 only. We need HDMI 1.4 in order to achieve 1080p60 3D mode transmission. Furthermore, as we can observed in Samsung 3D-TV, in practise interlanced flickering is very obvious when image is displayed under 3D mode. Even the European Broadcasting Union recommend 720p over 1080i for stable and clear video transmission!
