gt4 does 1080i ingame

The fact that an official name has been attached to the mode ("Hi-Vision") suggests to me that it is real.
i wasnt gonna rush out and buy GT4 either but if it does indeed have 1080i in game +1 sale from me.Hehe, GT1's "hi-res" mode was just false advertising. 
It ran at the same res, but at 60fps. At least the japanese version had the decency to call it "Hi-fi". Reduced detail was almost worth it...what a different the framerate made.
Anyway, at best this Hi-Vision mode will be similiar to Hi-Fi/Hi-Res. Still, *extremely* impressive(consdering this is GT4 we are talking about), if true. Strange that Polyphony kept it underwraps.

That's what's being suggested on the GTPlanet thread:
"it's real 1080i dude
the 480p mode even use Antialiasing for some objects and leaves are polygons this time!!!!
for 1080i, objects are become simpler than 480p, but you can see really far and really clear"
I'll take it.

Well, Faf seems skeptical, and given his credentials, i'd be more inclined to believe him than some random dude on a GT fansite forum.

What Faf doesn't take into account there is that 1080i does not have to be 1920x540. Horizontal resolution can be smaller.
Neither of those options actually renders HDTV spec 1080i though, you're cheating with up-scaling.pcostabel said:
And if that's the case, my guess would be it's simply rendering "720x480P" internally, which is the second HDTV mode PS2 outputs, and then if TV supports 1080, this is upscaled to 1080i with CRT. (and with interlacing, giving you 720x960).
Especially taking what you said about HDTV sets into account, this mode would be the most obvious way to go - it's marginably lower then 960x1080, and basically has no special requirements or performance sacrifices from the game. (the game could very well use 720x480 backbuffers in every display mode).
As for ideas with no double buffers or no ZBuffer, they are all pretty absurd in a 3d game. Even doing multiple passes and swap blocks in/out of main memory would be more feasible, although you'd sacrifice a lot of performance that way.
I debated the feasibility of 1080I, not the upscaled workarounds (I did mention the possibility at the end though).Marc said:
And anyway, above is my take on that issue too

Hey Faf, I remember the HDTV feasibility thing came up years ago when discussing the frame buffer probs for the eDRAM. But since you guys were doing a racing game, didn't I ever mention Kaz's claim of GT3 running at a higher internal resolution before being supersampled? I thought he said something along those lines. Meh.
BTW, I expect we'll be seeing graphics like this in-game next gen:
Anyone got a link to the GT4 intro FMV? PEACE.

I am not an expert about the issue at hand, but someone said that even by the HDTV spec, 1080i can be less than 1920. They mentioned 1440 as one confirmed option. Also, it's been said that many TVs can't even show full 1920 (or even 1440?) pixels anyways.
LOOK -- it's more than a safe assumption that GT4 will run in progressive scan (480/1080/whatever). It's confirmed on the SITE. 5 pages to argue over something that's easily verifiable with a few clicks.
From what I understand, 1080 is solely for photo mode. Still, this engine running on 480p is impressive enough, is it not? GT4 is clearly poised to be the most impressive game this generation has seen.
jinx, I think much of the incredulity on display in this thread is attributable to a good number of people here not wishing to give the ps2 any credit. I understand that cobragt3 is being a tad bit effusive, but he does have something of a point.

xs, you mean good but you must realize that 1080i has been suggested usable in gameplay. I doubt the res format for photomode would be in the menu screen for the game, instead it would be in the photomode menus. I can understand why alot of people find this not true, I mean, gt4 looks so damn realistic it's crazy and it's on the ps2. But rest assure this 1080i or 480p in gameplay is true and I hear leaves on the ground are made of polys now. I got that little info from one of the members of gtplanet who has gt4 and has mentioned 1080i ingame 
He was referring to what basically every game running on interlaced display does - sampling data from 448/480 lines into 224/240 that is actually shown on TV every 1/60th of a second.Duane said:
Which is why I brought up 720x960I as the likely actual resolution used.Marc said:
GT3 was already rendering at 480P(much like 95% of PS2 games do) - only the front/output buffer was half height, which has no bearing on performance.XS said:
Anyway, like I suggested above, running 1080I video mode with an upscaled smaller picture is a viable option without performance sacrifices - it's not "really" 1080I, but it would look sharper then regular NTSC.
It is entirely possible that the PS2 may have been pushed to do something previously thought impossible. As a PS2 owner (though not all that much of a racing sim fan), I'd be damn impressed and excited -- I'm not rooting against progress. However, there are some valid reasons to be incredulous. I agree with you -- 480p with an optional 1080i mode for more-or-less "still shots" sounds possible.XS+ said:
However (as the old saying goes), extraordinary claims require extraordinary proof...and cobragt3 has not brought ANYTHING to the table except hearsay. That's why I'm pissed at him.
That's something I never got. Apparently by using half size front frame buffer you gain a few KB for texture usage (loved when Guerrilla said that because the gain is ridiculous)...but you don't save any kind of performance since you are building a full back framebuffer for interlace filtering...Why don't we render rear buffer at half the size too ?

"WTF is DCharlie doing?"
... working?
It's 2:36pm here - i have to make a living!
Saying that, just been to Akihabara.
GT4 is running at most places, but if it has 1080i then nowhere is using it...
or 480P for that matter...
I never understood this - why demo a game and then have it running on big HDTV screens but via composite! Sofmap have it running on a large screen via composite but with only the white audio plug put in....

I don't want to see your excitement result in a ban. Calm down and bring us something more definitive than unverifiable accounts from another forum. I do think GT4 supports progressive scan in some shape or form, from what's related on Sony's official site. Still, none of us know if it's implemented ingame or restricted to the photo mode.

I'm sorry, but the "hearsay" is you. I'll usually side with board members over juniors when rumors and stuff are concerned but this is not remotely a rumor. It says so on the official site and it has been confirmed by several people in Taiwan with the game. The fact that the press is slow on their import coverage and that Japanese stores themselves don't break street dates don't make a single difference. You're acting all hostile and stuff but you don't even really bother to check YOUR facts, I'm a little disappointed.

Well good then because GT3 is unplayable on an HDTV. It's like daggers on the eyes.

Okay - 30 mins of work left.
I'm gonna check it like this - if i force my projector into a mode (480p or 1080i) , if it doesn't get a valid signal, it scrunches the screen up into the top half of the screen.
Rather than me saying "oh, well it looks like it's 480p" this should tell me exactly what the rez is and exactly when it's using it.
Note that i've played the arcade modes of GT games mainly, very little Garage mode experience, so i'll be as much use as a condom machine in the Vatican in terms of comparison based questions (e.g. : "How is the garage mode compared to GT3?" etc etc)
I will be concentrating on the vital stuff : How good does it look? and what is photo mode like?

Cool as ever Maskridermaskrider said:Just bought the Japanese version.
When you have time (and mood) it would be cool if you could try to do gameplay shots at different resolutions to see the effect
Edit: Now that I think on it it's impossible through a TV-Capture...pehaps with a camera.

Is there a noticeable degradation of the graphics in 1080i? PICS!!!!

I want to, but I don't have a device to take screenshot for higher than 480i sources. Well, may be a digital camera.
Later. Have to start playing now.
Someone copy this to the first post, let's sticky this thread and end the fucking speculation already. Jesus, when did we get THIS skeptical? There's been vaporware and lies before, but this one had no such signs IMO. Good to hear, and once again, I must say, Polyphony Digital >>>> *. Bow down to your digital rulers. :lol PEACE.maskrider said:
