Rendering 3D Slows Down PS3 Game Performance

[gti88]

Of course, developer are going to have hard time considering that 3d stereo requires 100% more grapfix power.

this is kinda've a duh.

You have to produce either 2 pictures or a single larger picture and do some postprocessing and replicating to get 3D to work. For 3d to work you need 2 images that are displaced a distance approximately the width between human eyes. Postprocessing is the most time consuming programming in games. More of it is naturally gonna cause large frame count hits especially if 2 pictures are done with independent postprocessing.

i'm pretty sure the slow down apply to existing game converted to '3D'.. if a game is written natively for 3D, the performance/graphic should be on par with regular game.

Whatever happend to VR headsets??? 3d stereos has been out for donkeys "woohoo" .... Not

Just make only a few games 3-D then. problem solved.

[citation][nom]surfer1337dude[/nom]I would think that if a game was reduced to 720p then games that come with 720 would not need to be reduced since it would be its "limit".[/citation]
That's not how it works. Two entirely separate images need to be calculated, so the framerate will always be about cut in half.

A game that runs 720p30 in 2D will become around 500p30 in 3D. Or in other words: SD

[citation][nom]blevsta[/nom]Why don't they just increase the width of the standard resolution and each eye gets the same image either shifted left, or shifted right? It can't be that easy can it? People higher than my paygrade better be able to think of that![/citation]
People higher than your paygrade apparently understand why your proposed "solution" doesn't work. You have to shift the virtual camera to get a different perspective. Simply cropping different parts of a wider image doesn't give you stereoscopy.

sky aint actually blue... just in case u didn't know
tho the sun is hot. u got half of it right

Said this when I first heard the PS3 was going to have 3D games. On the PC, playing in 3D usually cuts frame-rates by 40%. No way can the PS3 handle this when they can't even render in 1080P 90% of the time.

I don't know the specifics of HDMI 1.4 but I suspect that it's mostly hype. If you can run 3D bandwidth over a DVI cable, I don't see why it wouldn't work with HDMI 1.3

Maybe if you connect two consoles, one to one screen, and one too another screen, and mount the screen one on each eye...... Uhhh......Nevermind.

Wtf, the bare sky without clouds refracts light in such a way that when it meets our eyes it appears as blue.

How on Earth can you say it isn't blue?

[citation][nom]frostyfireball[/nom]looks like its time for the PS4 and the XBOX"720" to come out if they want to implement 3D with any decent results. I definitely saw this coming ever since they announced their intentions of adding 3D support[/citation]

Agreed, the notion of adding additional rendering overhead without sacrificing something else does not work. What they are doing with WipeoutHD is a work-around to maintain usability.

There are other games that run at acceptable frame rate, at 720P, that I predict will suffer greatly due to this change.

As much as I hate to admit it...
... enter PS4.

The headline confused me too.

 

[ksampanna]

Well that's what you get when your graphics are nothing better than an 8800gt.

 

[anamaniac]

Why can't the feature of multiple point of views (such as used in 3D and FSX) be added to more games? Just to point it out, 3 point of views would reduce FOV stretching when running multiple monitor setups, even if at the cost of frame rates.

Sony, why don't you just throw out a new 3D version of the PS3? You sure don't seem to mind screwing your users over on a regular basis, and you could replace that crappy 200GFlop GPU with a 400GFlop one to fix the issue. My lowly 5770 has 1360 ponies under the hood...

I wont buy any 3D stereoscopic system with glasses, be it a home monitor or tv or a game console.
I will wait for something with no glasses or hologram like.

This 3D systems have being trying to penetrate the market for decades and they fail to standardize because they soon become an expensive curiosity. This time they come cheaper than ever but still depend on the venerable glasses. All in all great if you want to get closer to a real 3D, then this is an option.

No shit Sherlock.

This just in, Using an Eyefinity setup slows down game performance.

I would personally rather see bettering looking 2D games than 3D games.

 

[zybch]

[citation][nom]bogcotton[/nom]But so much of the data is exactly the same from frame to frame, there is just a slight shift of the image with a little extra info.If this was coded well I would expect only a 5% performance decrease frame for frame.It just seems software guys have lost their artistic passion for coding.[/citation]

You're right, sort of.
For bluray video content in 3D, the 2nd video channel ONLY consists of the changes compared to channel 1, this adds less than 20% to the bandwidth/processing required.

However, for a PS3 RENDERING the 2nd channel in a game, its going to take up 100% more processing time, extra frame buffers, and potentially some extra RAM out of the paltry amount Sony stuck in the console in the first place.
Now you can be sure that the game developers will be able to work a bit of magic and not require a full 100% more resources, but its still going to be asking more of the current PS3 that it is able to give, especially at 1080i/p.
