Image Quality and Framebuffer Speculations for WIP/alpha/beta/E3 games *Read the first post*

Well one render target we know is 720p is the HUD..lol

 

They are just describing pretty much every game out there, and it isn't really and explanation! Games frequently use mixed resolution framebuffers, like quarter-resolution particle buffers on PS3, and then combine everything into the final output. "720p" here means outputting a 720p composite of mixed-rendering framebuffers, without any clue as to what's rendered at 720p native or not. Everything so far is pointing towards a 960x540 main rendered opaque geometry framebuffer, what we gamers consider the game resolution, with a 720p native HUD/UI overlaid. This official response is a PR-phrased explanation of what they mean by 720p given that the game was described as 720p, and as usual '720p' is used when the output is 720p irrespective of the render resolution.

 

I think that when the gameplay releases and pixel counting starts and the resolution will be added to the official resolutions & tech thread, Alan Wake's resolution will be split in different chapters

 

That what I think also.

 

Thanks for the explanation Shifty that was the first thing I thought of.

 

Well, much of the post processing appears to be done in 720p though. I'd say it is sort of a weird area. I do agree that the geometry framebuffer is 960x540, but that doesn't necessarily tell the whole story of how the game we rendered. It wasn't necessarily a lie to say that it was 720p. It just wasn't the whole truth, it left out certain details.

 

Ok, so what in the post processing is being rendered at 720p then?

" These are used for example for cascaded shadow maps from sun & moon, shadow maps from flashlights, flares and street lights, z-prepass, tiled color buffers, light buffers for deferred rendering, vector blur, screen-space ambient occlusion, auto-exposure, HUD, video buffers, menus and so on. "

What in this list besides the HUD is 720p? And if they rendered the HUD in 1080p should they then be able to claim the game is in 1080p even though everything else is half or less of that?

 

No. I don't know exactly what is rendered at what resolution. I just think relying purely on the opaque geometry buffer is a bit dated when you consider modern engines... There is simply too much going on elsewhere...

I think it would be looking at it a bit too simply to say "This is 540p" and ignoring a lot to say "this is 720p." I think for the purposes of the resolution that get posted, go with 960x540. But, there is simply too many other factors to just call it 540p when discussing it...

 

Thanks Shifty. But when the final image is 540p (upscaled by the Xbox to 720p): does it even make sense that one of the "intermediate" buffers is > 540p?
As I understand it, you use typically smaller intermediate buffers (to save GPU) and not larger ones?

 

Well if I have understood some elements are 720p but the engine runs at 540p; where is the weird to say runs at 540p? No one said graphically is garbage but yeah the engine runs at 540p at the end.

 

I've moved the last three pages of Alan Wake talk to this new thread for discussing the game and choices. Please use that thread and return this thread to the determining of framebuffer and IQ methods of unreleased games. Thanks.

 

Did anyone see the last ViDoc from Bungie?

what about the res.? 1152*720 as before?
looks so beautiful anyway

 

Not too concerned at this point. One of their better improvements is that the specular aliasing is rather minimal throughout. The more pronounced motion blur (camera and per object) helps quite a bit as well.

SSAO is also present.

 

There's per object MB ?

 

I am not concerned at all, the game looks (and plays) sweet
I was just curious

 

Guys, what you can say about majin and the forsaken kingdom?
http://www.gamespot.com/ps3/action/majinandtheforsakenkingdom/images/0/19/?full_size=1

I get vertical resolution only 514p, am i wrong?

 

looks like 720p to me... The ladder itself is rather 1:1

 

I haven't seen anything, it appears they are showing the X360 version exclusively.
Does that mean ps3 version is running behind the X360 build ? Or is it a marketing decision ?

It's been 2 years since the release of GTA4, so hopefully they've improved the engine.
It would be nice for PS3 to have 720p native, and no dithering problems with X360.

 

do you think bungie implemented AA? or is it post processing doing a better job at hiding the aliasing.

Looks like QAA vs. MSAA to me They used SSAO or technique used in SCC
