>After getting my chance to mess around with the PS3 today, I stumbled upon a very unfortunate discovery.
>PS3's HDMI out only supports 480p, 720p, 1080i and 1080p. It cannot output a 480i signal from HDMI. But all PS1 and most PS2 games are only 480i . . . so what does this mean?
>Basically, the PS3 performs deinterlacing on the 480i signals from PS1/PS2 games so that it can output via the minimum 480p through HDMI. However, it does a very poor job of deinterlacing! Not only are there severe combing artifacts, but there is also a built in 2-3 frame lag, the same lag you would feel if you were to feed a 480i signal straight to your HDTV.
>Currently, the only way to avoid the lag is by outputting to an external scaler which can properly (and quickly) deinterlace the 480i signal. However, since the PS3 forces 480p on PS1/PS2 games through HDMI, there is a built-in input lag which affects all games and cannot be avoided. That means that the PS3 owners who paid large amounts of money for the iScan VP series will not be able to play PS1/PS2 games lag-free via HDMI, even with the "Game Mode" enabled.
>The PS1/PS2 games DO output 480i with Composite, S-Video, and Component cables. However, with Component cables as you know, the Blu-ray constraint token prevents you from getting a 1080p signal. Additionally, most HDTVs can't even accept 1080p via Component.
>This means that you'll lose 1080p if you go through Component, but if you use HDMI all PS1/PS2 games will have built-in input lag.
>No 1080i support was one thing, but I'm in a state of utter disbelief that the PS3 cannot properly output a video signal via Component nor HDMI. Since the PS3 cannot output both a Component and HDMI signal simultaneously, the only way to work around this issue currently is to tediously change output modes in the system settings every time you want to play a Blu-ray movie or PS1/PS2 game. This is completely unacceptable and should be addressed immediately.
>There are many possible fixes for this problem that could be implemented in a future firmware. Here are just a few of the ways that Sony could fix this issue:
<1) 480i output could be allowed via HDMI so that users could properly deinterlace PS1/PS2 titles with seperate hardware.
<2) There could be an option to automatically switch to the AV Multiout (Component) for PS1/PS2 games, while using HDMI output for other material.
>or, the best solution,
<3) Actually use a decent deinterlacing algorithm on PS1/PS2 titles, so that they don't lag and suffer from terrible combing artifacts.
>Now, while #3 would be the best solution, it's the solution I see the least likely for Sony to actually implement because it would take actual work. #1 and #2 are simple workarounds that could be applied, but they still don't do anything about the real problem.

>Yes they all have lag, no matter what.
>There's nothing you can do about this either. It's very slight, but it is there.
>Very noticeable on LCDs. Not so much on CRTs.
>Trust me, I've done extensive testing with multiple PS1/PS2 fighting games.
>This is why PS3s aren't used for fighting game tournaments at all (PS2 games).

>This time it's not caused by emulation but by the video post processing. The games are internally rendered at 480i and then deinterlaced and upscaled by the PS3 graphics processor. If you have a game which supports native 480p output and you set the PS3 to 480p output, then the lag is reduced a single frame

>On the PS3 side of things. Yeah it's pretty bad. I too own a release day Japanese unit, however I'm lame and Have a 20gb model. (You win this round, Fudoh) Gradius Gaiden is completely unplayable, and that game can be pretty forgiving. I haven't thrown Gradius III and IV in there (because I fucking hate those ports for being so bad. Why subject yourself to that when you have MAME for Gradius III and own a real Gradius IV PCB?) and tested it yet, but I'm sure it's just as bad. Shockingly, beatmania IIDX 10th Style was ALMOST playable on my PS3 when I tried it back with a CRT, although without a controller it's pretty fucking hard. Dualshockmania IIDX is pretty lame to begin with, but the timing did feel reasonably on spot. That test was done however with Component cables going into an Extended Definition capable television running at 480i (because at the time I was dragging my PS3 to and from school, where 480i over component cables was the only option) so maybe there's hope yet for using a PS3, but it's not worth the effort right now considering how fucking cheap PS2s are.
