As requested by GT in the *Post your Pics* Official Thread here are some screenshots grabbed in 720p and 1080i.
I posted all 208 on TaxiGamer's blog, check it out.

How we proceed :
All captures where pure digital signal through Playstation 3’s HDMI output.
As our hardware can only capture 1080i streams, we had to capture steady shots so no interlace fields are visible and ruin the comparison. And this way we get a 1080p “illusion”!
We recorded a “race” with a stopped car. We saved the replay and then captured 104 pictures at each resolutions, 1080 and 720.
Original screenshots were grabbed almost uncompressed (YUV 4:2:2 16 bit) and we share them as PNG files to avoid losses on our Flickr Photostream and the slideshows below.
The only thing we’ve added is the watermark. We didn’t de-interlaced them or adjust anything else.

You'll notice that 1080i screens look blurred, this is certainly due to the 1440x1080 resolution upscaled to 1980x1080.
But on my LCD (Sony KDL-32D3000) 1080i/p signal looks way better because it is downscaled to native resolution (1366x768)...

Ugh, 1080i is horrible for gaming.
I have a Samsung 2493hm and can play the game in 1080p, and this looks much better than those screens you posted.
But its still nice to see the direct comparison between the resolutions in size.
 
That mess in frames upon Ferrari engine is the worst issue of GT5p graphics, in every game frame it's jagged differently so it's almost hypnotising to eye and it immediately attracts attention.
 
This is a bad comparison, the 720 images should be upscaled to the same resolution as the 1080 images to show the real difference between them.

@G.T.Ace, there is no difference between 1080i and 1080p in terms of picture quality, 1080i is essentially 1080p at half the frame rate.
 
In Daytona road picture you see the polls in dictance dissapear because of jaggies, I didnt think that happend on 1080p/i ! Im happy too see 1080p/i picture dont look any better then my 720p :)

There was no need to quote the whole first post, dude. :)

Unless that's sarcasm, in which case I apologise, but he didn't quote the post, he upscaled the 720p pictures to 1080 resolution as suggested by the previous poster to allow a better comparison. 👍

Not if your TV has to scale the image up and down and whatnot.
The images here are a bit washed out and way too dark compared to what the game looks like on my monitor (note that i see the pics here on the same monitor so it has nothing to do with callibrating etc).
One thing that sucks a bit is that the image is slightly stretched in height because the PS3s output is 1920x1080 (16:9) and my monitor has a native resolution of 1920x1200 (16:10), but its okay, not that bad.
I also have the feeling the ground textures are more pixelated in your screens, but that could be my imagination. lol
 
R0M, I would really like to thank you for all the trouble you've gone through. Seriously, I absolutely appreciate the effort and I thank you again. The folks at GTP really amaze me; obviously most of us are car nuts and hence love the GT series. It is nice to know that at least some people (that's us) can behave with respect to others.

Again, thank you R0M! Great job!

now on to the interesting parts. First of all, the reason I wanted the GT-R from the cockpit view was because of the stitching of the leather on the dashboard; it is a good indicator what the real difference between 720P and 1080P would be. I curiously enough it seems to me that the difference is non-existing; or at least very difficult to actually see (one might even go so far as to say that 720P version looks better...)

Overal it gives everyone a good indication of the difference in quality, and that is important. Now let's see what everyone thinks :)

I'm no expert or anything, but I've heard that 1080i is horrible for videos, but fine for gaming. I only have a few games that run 1080i on my PS3 (some upscaled?), and the others play in 720p. While I can see a little difference in picture quality, they both look damn good and a lot better than the old 480i picture I had to put up with years ago.
 
No 1080i is "bad" everytime a fast changing image is used, videos, games etc.
i=interlaced, which means the image is made of single vertical lines that rapidely change to give you a full image, same method as on old CRT TVs, just in a higher resolution.
p=progressive, which means the image is really one image.

Personally i would always choose 720p over 1080i.

By the way, for anyone who doesnt know what the numbers mean:
720=1280x720 pixels
1080=1920x1080 pixels
 
my 2 cents
I do not compare 720p and 1080p by the screenshots. I'm lucky to have that compared by my two TV's with my own eyes.

LCD Toshiba 32'' 100Hz HD Ready
I used this TV for GT5P from Aug.07 till Nov.08. Now it's in my bed room ).
It handles 1080p input.
Experience:
720p native resolution - good, very good picture quality. Some jaggies and flickering here and there.
1080p downscaled - to my strong opinion the picture was a bit sharper and definitely less jagged.

Plasma Panasonic 42 Full HD
I've been using this TV for GT5P since Nov.08.
1080p native resolution - very very sharp picture, way sharper than that on my previous LCD. No jaggies whatsoever.
I was impressed to see digits sharply in most of the cars. To check that I compared the Vette, Viper, R8 and some other cars' interiors, also noticing "X 1000 rpm", "audio" and other letterings and symbols not visible or readable before.
The tacho at the bottom right now has single lines, no mess there.
Overall picture is sharer and deeper.

720p downscaled - The picture looks washed out. This is definitely more visible that that on the 32 LCD due to the bigger size of the TV.


I do not compare plasma vs LCD, 32 inch vs 42 inch, I just compare 1080p native, 1080p downscaled and 720p resolutions.
Conclusion: 1080p native resolution wins hands down. But 720p will do fine unless it's 40'' and above.
 
Thanks a lot ROM!:cheers: 👍

Too bad it won't capture 1080p

But its nice comparison.


By the way, could you stretch the 720p pictures to the same size as 1080? Because you only play on ONE TV ;) its the resolution that changes not TV size HAHA!

On my setups, when I switch between 1080p and 720p, it looks much more jagged on 720p then 1080p, I notice it mostly in cockpit view.
 
The stretching of the 720p images with a program like Photoshop would destroy the comparison, because it will scale the image too good.
 
My tv looks much better if I play in 1080i. My tv is an HDTV CRT Sony Trinitron Wega.
So the people saying that 1080i is terrible compared to 720p are not correct. It truly depends on the TV.
 
Thanks for all your comments guys.

Enlarge 720p screens to match 1080i/p size isn't a good idea for comparison. Simply because there are so many resample algorithms out there, nearest, bilinear, bicubic, Lanczos etc. Also because algorithms are different from a TV to another, some have good scaler, other produce ugly results. And we don't even know witch algorithm Playstation 3's internal scaler uses.
I think, a fair test is to download some screens I made on your PS3 and look at them downscaled/upscaled by the Playstation's XMB. This way you can determine what fit best with your installation.

About 1080i versus 1080p. As I grabbed steady 1080i screens, results would have been the same with 1080p input.

I was surprised like you by the results. I don't notice this difference on my 32" screen. 1080i/p signal don't look that blurred. It's even the opposite, 720p upscaled to 1366x768 is blurred as hell!
 
There is some dragging/lag with moving images on my aging Panasonic 1080i rear-projector (component only, no 720p). I've been switching from this TV to a recently purchased 23" Acer HDMI 720p monitor (they are very close to each other in the living room, the PS3 is between them) over the last week or so. My still images are very similar to the pictures, but the monitor is better than the TV when both the camera and the subject in focus are moving during both gaming and movies. The TV is still very good for games and stunning for movies when the camera is stationary and focus-locked on it's subject.

Obviously any comparison is subject to variables, the Acer is not the greatest gaming monitor ever, and I have to get the convergence (alignment of the projector lenses) perfect :scared: for the Panasonic to be at its best.

The overall impression when viewing each type, both in the above captures and during GT5P gameplay, is that 720p is sharper, but the 1080 is somehow more lifelike. I felt the same watching the Bladerunner BR movie. Right now I'm really enjoying 720, and finally playing F1CE at its proper resolution has been a revelation. I honestly can't say which I like better, each seems to have advantages for particular uses, I'll enjoy having them side by side.:)
 
You should warn ADSL and lower speed broadband users too. :P Page is about 25% loaded after 3 minutes.

I'm out of here before i run out of my monthly quota, but from what i saw some of the shots looked great in 1080, and some looked a bit crappy. (like the first one which i spent 5 minutes waiting for it to load. :grumpy:
 
Sorry about that.
I published PNG to avoid compression artifacts.
Here it's more the browser that slowdowns, not my 100Mbps connection :D
 
GTAce: I have same monitor. I have same picture as you said - it looks much nicer and crisper than 1080i shown here on these screens.

PS: I had the problem with stretched image too, but after a couple weeks I found an option somewhere in menus and The picture is now better with 2 small black stretches. I have no idea, what exactly it is, as I was just playing and trying out settings and next time I used PS3 it was perfect. And when I use it for PC, the image is nice 1920x1200.
 
P or Progressive Scan is always going to be better than i or interlaced..

When I looked at the pictures, I thought that 720P looked better

1080i is def junk.. I think 1080p ould be a lot better, if the game could pipe that signal..A lot better than 720P
 
I think that the comparison of these images is wrong. You must submit two images the same size: increase the image 720p or decrease the 1080i.
Ideally decrease 1080i images.
 
Having read the news section about this thread I have set my PS3 to 720p instead of 1080i, and I can't believe how much better the picture is. Straight away I can actually see at distance the writing on my XMB. U have had to squint to make out certain letters previously.

Excellent Thread.

Uh, no, not junk. Did you read what I wrote? There are advantages and disadvantages to each format. If you don't have a decent 1080i set to base this opinion on, why persist? All HD television is broadcast in 1080i, is that junk too?

I still fail to understand how a captured 1080i image is any different than a captured 1080p image, it's all up on the screen when the capture is "taken". If there is a difference, why do we see the entire image with the 1080i, shouldn't half of it be missing? As I understand it, they are different only when displaying images in real time, not for stationary captures.
 
Because the TV has a different resolution than 1920x1080 and scales the image which leads to missing picture information, just like you can see in the pics R0M posted.
The 720p images are sharper because they're not upscaled.
If you have a 1080p native display you have a higher resolution and sharp textures.

There are TVs that do the scaling better, but in motion, interlaced pics cant be better than progressive at least in motion and when the image has to be scaled up and down and whatnot, also in static screencaps.
