And you have 8 pixels of black bars on both ends.

The screenshots show a slightly lower resolution horizontally (maybe 1024?), but it could be the capture card not sampling at a high enough frequency.

Dot50Cal, can you show us a screenshot of a known 720p game w/o AA, like Gears, and find a near-vertical edge? That XBox screenshot you posted doesn't really tell us how good the capture quality is. Antialiased text scales pretty well.

In any case, I don't think it's a big deal. Lack of AA is affecting the edges more than upscaling.

a la the Gamespot images which are native 1280x704

Heh, well we all remember Halo and the released screen grabs, right?

[Dot50Cal]

My 360 red ringed a few days ago, so I cant provide any 360 shots But Ill see what PSN demo's I can get that have no AA.

Gears does have AA though, and it seems Heavenly Sword does too, this might be hard without the 360.

Though I do have some shots from Halo 3, if you are trying to determine the cards vertical scaling capabilities then it would probably work.

Open Dir. Though I believe these might have slight artifacts due to capturing them rather than direct screenshots of raw gameplay, so ignore them if you find them.

Edit: Is the Sigma demo 720p? Heres a shot from that:

Gran Turismo 5 Prologue Demo is out. 1440*1080 still, no AA, sigh...

Most assumed it was this, based on GTHD

Is this confirmed, anyone done the necessary testing?

[Dot50Cal]

Looks like it has AA to me. Im not sure if these shots will help in the step counting, as the 1920x1080 shots are 1080i (my card does 1080p at 960x1080) but I thought they would help.

I took this quick snap last night whilst playing in 1080p:


Same place in 720p:

[Quaz51]

GT5 prologue demo is 1280x1080p (yamauchi know than in car game the vertical resolution is the most important for the visibility) but with MSAA 2x now ! it's a very good Compromise
they also very Improved the display of grills and electric wires and aliasing problems (compare electric wires in GT-HD and in this demo, it's big big gap), the texture filtering is very clean and the HDR ligthing is awesome! all this in 60fps with 16 photorealistics cars, it's Impressive!

the show room and the pit/garage is full 1920x1080 no AA

[Quaz51]

they improved the 720p mode too, it's MSAA 4x now

Are you sure? lol

I don't have street cred lol True I did say it as if I was certain, but I trust Quaz. Hasn't let us down so far. And when I look at that 720p screenshot I also see 4xMSAA. Meh.

I'm just messing with ya

What do you think about the aliasing? Some people seem to be annoyed by it. I'm guessing it's much harder to do AA for close objects that have straight lines.

How does it fair with PGR4?

[Shifty Geezer]

Could it be HDR? AA averages samples, but where samples are of a highly contrasting amount, the average could still be beyond the bright limit after tone-mapping. eg. If you have one sample white 1.0 and another black 0.0, the average sample would be grey 0.5, adding to AA. Whereas if you're bright spot is of intensity 5.0 in HDR, the average would be 2.5, and if you tone-map that image to 2.0 being the white limit, the averaged sample will be 'overexposed' and rendered white, contributing nothing to AA.

You sure?. I've got a 60" 720P tv, and run it in 720P and the game looks pretty jagged to me.

[Quaz51]

for me GT5 prologue is more clean than all other cars game like PGR3, Forza2, PGR4... (2x PGR4 framerate, 2x PGR4 MSAA, 2x PGR4 nb cars, better filtering, photorealistic lighting...) replay with this others demo for compare
the visual comfort and the visibility is awesome in this GT5 prologue

Wait. 720p 4xMSAA in replays only, or gameplay?

Because I've come to realise that F1 on PS3 is the cleanest racing game with it's 4xAA (and HDR :P)...I mean that's almost buttery smooth.

[nAo]

F1 has HDR..

Oh ok...pretty spectacular then. One of the few games to do 4xAA and HDR along with Heavenly Sword. They had an impressive engine then.

do you mindposting a in game screenshot? or is 4xAA during replay?. Cause Ise gets lotsa jaggies might be my tv settings though.

i often noticed in lot of games that bloom/tone-mapping have a bad effect on MSAA, Partly disappears in Some cases ( distrust this when analysis msaa on game)

[wco81]

So are the people who did F1 working on anything else? Isn't Sony's exclusive license for F1 running out?

i talk only in game situation

F1 is AA 2x, too blured and 30fps, GT5 prologue visual is very more cleaner and pleasant
