Dear Sony, fix the damn PS2 emulation

Trying DQ8 is fun. It looks good, but all the fine lines due to the art style create alot of shimming/jaggies. I don't know if this was the case playing directly from the PS2.

DQ8 looks much better on PS2 via S-video than on the PS3 via HDMI on my display. The jaggies are distracting enough that I couldn't play it on PS3.

I'm surprised that Sony hasn't even acknowledged the problem yet. It just sucks to wait.

Huh? Why on earth would anyone expect any different? We are still talking about the same people that told me 2 of my PS2's in no way, shape, or form, had any laser problems. They said this after they were presented the huge mountain of evidence before the lawsuit. They still stuck to their guns and only changed tune after losing. Do I expect any different? Not really.

EDIT: However, with their recent willingness to update stuff rather frequently through firmware, we might just see an update with no talk about it ;)

I don't think anyone asked my earlier question about why you shouldn't run any PS1/PS2 games with the display settings at 720p or 1080i/p. What's wrong with that again?

I don't know what's wrong with that since your PS3 outputs in 480i/p ONLY. So even if you change the settings in XMB, it'll still output the same.

Don't PS2 games look like this on an LCD HDTV anyway?

Edit: Don't have a PS2 but I plugged my gamecube into a HDTV for a game of F-Zero a few weeks ago and it looks jag-tastic. Even Ocarina of Time seems more jaggy.

I tried SSX3 over lunch. As you said, it clearly runs in 512x512. Enabling progressive scan produces an image no different from that of the PS2, however (expected, as the PS3 is no longer de-interlacing the image). I also tested Silent Hill 2 and Tekken Tag.
Silent Hill was also known for using a different resolution and the results are every bit as terrible as those Square-Enix logos floating around. Tekken wasn't nearly as bad as expected, however. A bit flickery, but overall clean enough.
That just confirms what I've said in the original post.
Horizontally misaligned pixels (like the Squenix logo) happen when title output an odd horizontal resolution (eg. 512). Tekken (as most early titles) was using full 640, so it will not be affected.
Progressive scan "fixes" things because titles change their Output buffer to 640 (so in case of SSX and others like it, title renders 512x512, then scales contents to 640x480. When the same title runs interlaced, 512x512 is copied to 512x512 and CRT handles the "scaling").
The issue is not in deinterlacing per se - it's scaling of the 512 signal to fit 640.
This is also why ICO works (640x240), while SOTC has problems (512x512, except when running progressive).

Anyway ... I do wonder if there are any progressive games that use non-standard output resolutions?
No, if you tried outputting progressive in non-standard res, it would just get displayed in a smaller window (which wouldn't pass Sony Q&A). See above how games handled this.

are we sure the PS2 even scaled the images at all
It's "scaling" by outputting a different H frequency (as you noted yourself). So pixel just becomes stretched on the CRT display.
But this only worked for interlaced outputs - PS2 CRT wouldn't allow this on progressive (so we would scale the buffer before outputting it in that case).

manp said:
a combination of non-standard buffers and deinterlacing algorithm, may be something like this?
Well, it appears (on PS3 at least) to be horizontal scaling problem, but yea, it's clearly a problem of how scaler works. My Samsung LCD doesn't do this, so I can't say if TV has the symptoms with same titles.

Afaik software emulation on PS3 is already better then 360 ever was, whether it'll ever be 97+% I wouldn't know though.

This looks exactly like what happened when I tried to play Gundam: Climax U.C. with the Xploder disc @ 480p. Except, that looks even worse than the current PS3 problems since it looks like there's a ghost following everything when I did that

But the titles that do work don't end up looking like total ass.

Both solutions are lacking. Hopefully at some point we see solutions with the compatibility level of the PS3, but with smooth graphics for all old titles regardless of original framebuffer resolution.

? The PS3 isn't doing software emulation for backwards compatability I thought? Or are you referring to something else.

So it all comes down to lack of scaling on PS3. Fixing scaling could fix so many issues if that's even possible.

Thanks for the corrections & info. As always ... you kick ass!


Would you agree that if they can't find a clever way of scaling the image digitally ...

... then they should at least update the PS3 to do passthrough over the analog outs (assuming that is possible)?

Fafalada,


Actually, this brings up an interesting question. Does the PS3 have the ability to do 'scaling' (h synch) on it's analog output?

If so, this would be a relatively simply solution for PS1/2 games - other than the configuration of video outs being a little convoluted, as well has being forced to use analog (at least for interlaced games with 'odd' resolutions).



If it is the case that the PS3 can do this ... the bigger question is ... can it be used for HD resolutions?


Think about it ... that could be the solution for PS3 games as well!!


The people that have TV's that do not accept 720p ... they could use analog outs if the PS3 can scale the image to 1080i. That would be perfect.


People with HDMI do not need to worry, since basically all HDMI TV's accept 720p. Any that don't (are there any?) must be 1080i CRT's. In their case, there really isn't a reason to actually use HDMI/DVI since the TV has to convert it to analog anyway. Those TV's don't really benefit from a digital signal ... so they might as well use analog.

If all this theory about the resolution being the key factor is actually true then I guess RRV might be like a really "nice" thing to see on a PS3... Because if the original one was already a bit jaggie, with this pixel messing could be almost incredible to see...
I don't think this is really hard to fix... Isn't the PS3 just soft-emuling all those titles ?

No, it has an EE/GS chip inside of it.

The question is whether the output controller has the ability modify the h-synch in order to 'scale' the image.

Also, note ... this will only solve analog output - not HDMI.






As for RRV, I'll dig it up and test it this weekend. Whether it looks terrible will be based on what resolution it was actually running at. The jaggies it had were not directly related to the resolution, but were the result of field-rendering, no interlace filtering, and 60fps to my knowledge.

This is an honest question.

Do we really know enough about the PS3's internals to make blanket statements like this? There is some sort of software layer running during "PS2 mode" on the console, otherwise the system wouldn't have return to XMB, "connect controller" dialogues, or this attempt to scale to 480p in the first place, right? Do we really know the limitation on what kind of software solution they could shove in there?
 
i request psone test!

btw seems sony should embed edram to rsx. take out ee/gs. put in forudja dcdi scaler. it be awesome like ps2. too bad so sad.

It's not actually trolling if you don't admit it
MGS3 already tested?

What about GT4? The GTA games?

Gradius V? Contra Shattered Soldier? Dark Cloud 2? ZOE2?

I ran a few PS2 games for fun to see what worked.... after a few I got pissed and stopped :lol

here are the results:

Yakuza - FAIL
MGS2 - FAIL
MGS3 - FAIL
ZOE - FAIL
CMR3 - FAIL

Street Fighter Alpha Anthology - PASS!
GT3 - PASS!
Ace Combat 4 - PASS!
Radiata Stories - PASS!
Gulty Gear X - PASS!

tried to hit a few that haven't been covered. ZOE2, GT4, and Katamri are all out on loan sorry (I need to get that shit back!)

PS1 games I tried all looked OK for what they are GT2, Bushido blade 2, and Soul Blade didn't seem to have any issues.

One cool thing I noticed, if you put in a PS2 CD it shows up as blue in the XMB :lol

I wish I could take cool pics like DCharlie to document this but my digicam is officialy dead it seems :(

SMT looks terrible, I tested yesteday through HDMI in a 26" Bravia. Really, really bad, you don´t want to see screens.

Is a disgrace, hope they fix this and fast.

I was playing Abyss on PS3. Looks like utter trash. Has the same blocky issues as Okami and FF12.

what model is your Samsung LCD? which connection do you use?
just to know :p

Do these graphic problems only happen when using HDMI?

Here is a thought. When you run PS1 generation games of anything higher composite the graphics are horribly pixelated. Perhaps component is the highest PS2 games can go before they suffer from the same problem?
