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."

Movies can be displayed at 1080p@24fps because they are temporally aliased, that is, they are 'blurred' over time. A single frame in a movie consists of all the light from 1/24th of a second blurred together, a single frame in a video game is a snapshot of the exact position of all elements at the time of rendering. Because or brains can notice these exact frames, kind of a like a flipbook, we need more frames in order for our brains to interpret them as motion. So while 1/24th looks smooth for a movie, 1/60th looks smooth for a video game.

Regarding 1/24th of seconds for cinema, you are incorrect. When shooting a movie you can capture a frame at anywhere from 1/25 second (if shooting at 24FPS) to around 1/10000 of a second depending on the camera and available light. What's more you could easily simulate what you call temporal aliasing in a video game. In fact many games already do this, even for the PS3. This is one of the benefits of the Cell processor...

I think you mean 1/48th of a second @24fps, 180degree shutter. With no shutter, you could capture at 1/24th, albeit with a lot of smearing (film) or blurring (imager). But who would do that?

And if you compare 1/25 of a second to 1/10000 of a second, you'd see smoother results with the former as opposed to the latter when played back at 24fps.

Sure you can simulate temporal aliasing in video games, but it requires a substantial amount of processing power, it's not trivial, it's actually easier to just output 60fps than to output nicely temporal alias'd 24fps, the point is that the processing required to produce smooth 3d video games is greater than is required to output smooth 3d video. (As for the shutter speed stuff, I didn't want to have to post an entire wikipedia article to tell someone that you can't say "you can do it in movies, why can't you do it in video games").
