PS3 PS3 backwards compatibility lag

[Saltygram]

Some people say the backwards compatible ps3s introduce a ton of lag to ps2 games, others say they don't. Has anyone here ever experimented with this?

I can get a cecha ps3 for pretty cheap and am wondering if I should do it, or if a ps2 with an upscaler is better.

What kind of lag are we talking, input lag or lag from the hardware itself?

tf u on about?

ur ps3 must be at the end of its life cuz im having no problems with "input lag"?

Input lag, I've heard that when the ps3 upscaler is used for ps2 games it gets really bad.

Not really, you are running under a PlayStation2 Hardware, the input lag is pretty much the same, unless you are a Hardcore Retro Gamer which are demanding with the equipment.

Upscaling the PlayStation2 Format Software on a PlayStation3, doesn't produce any form of input or hardware lag, the Upscaling is all handled by the Reality Synthesizer or the RSX.

If you are really worried, which fear not, you need to be, use a CRT or a real PlayStation2 if you are worried, Digital TVs have a slight input lag, due to how the digital signal is handle, from the Analogue Counterpart, or use a High End TV or Monitor with a faster response time, but generally speaking there is no input lag on the Backwards Compatible PlayStation3s, i own a 60Gb myself, and i see no noticible difference between a real PS2 Hardware and the PlayStation3.


Now if we are talking about lag within games, then yes, on Backwards Compatible PlayStation3s, there are a few minority of PlayStation2 Software Format, which you can experience a bit of incompatibility, thats on the CECHA/B Models, for the Semi-Backwards Compatible, the CECHC/E, PlayStation2 Format Software incompatibility its a bit higher, but nothing deal breaker, its expected from a console that hasn't got a complete PlayStation2 Hardware, even the A/B is missing a PlayStation2 Hardware part, which is the I/O Processor, which has been replaced with the CELL B/E, both 4 models, use a conjunction of PlayStation2 Hardware and Software Emulation, but the C/E Model uses 25% PlayStation2 Hardware and 75% Emulation to replace the missing PlayStation2 Hardware, but both handle PlayStation2 Format Software almost flawlessly.

I guess using a wireless controller for PS2 games when you are used to a wired controller must add a little input lag, maybe thats what you heard about. You can connect the pad with a cable if you want.

I like to play Capcom vs. SNK 2 and the input lag is very bad on the PS3 FAT. I've the original disc and thought "well, digital must be better"....purchased the PSN version, but nope...the input lag is still horrible (no matter what your settings are). It's true, a CRT TV helps but it's still not fun to play, even with a wired controller/arcade stick (at least for me, someone who likes fighting games). For just button smashing or games were the input lag is not important, I guess it's okay

untrue. ps3 analogue output has lag

it does produce lag. the framebuffer is always activated no matter what, resulting in a guaranteed delay

This is a very interesting topic and should be looked into it. Input lag depends on how bad deinterlacing is on BC PS3 and how it handles frame buffer. Would be nice to test it.

PS3 Full BC only has lag while playing PS2 on the analogue video output, even if it's outputing to a CRT. If you connect the PS3 by using HDMI while playing PS2, the only lag you will have is from the TV/Monitor itself, not from the console. My Life in Gaming has tested it long time ago in one of their videos about the ways to play PS2.

Full BC PS3 for sure adds input lag even with HDMI. There's quite a night and day difference with the input lag between a real PS2 and a BC PS3. It's most likely caused by a triple buffering, so it buffers couple frames to the RAM before sending the frame out to display. One thing that supports this theory is that games such as Outrun 2006 have a 480p mode, and the resolution change happens so quickly that the PS3's image signal to the TV does not blank out basically at all. So the PS3 immediately notices that the resolution has changed from 480i to 480p, and that can be done without dropping the signal with triple buffering. That is really hard to do without having a buffer, like with some upscalers you have to use the triple buffering to get the HDMI video signal not to blank out when there's sudden resolution changes.

And let's say that if the full BC PS3 didn't have any kind of triple buffering in PS2 mode, then the input lag caused most likely by controller input handling. One thing I'd like to try but I don't have one is using Dualshock 2 on BC PS3 with a USB adapter. I've heard that with BC PS3 PS2 games can work with official Dualshock 2 with USB adapter. I don't think that it would make any difference to input lag, but who knows if Sony had to make the PS2 mode input handling with DS3 in a way that adds input lag.
