You can turn off the upscaling of PS2 games. IIRC there are a couple of different settings for this. I can't look at mine, I sold my 80gb BC unit a few months ago.

PS3, PS2 games, 480i, and lag

Really it probably comes down to your tv. While obviously scaling adds input lag and the tv having to deinterlace adds input lag it can vary whether it is HDMI or component that performs better. It varies tv to tv.
In fact in theory HDMI should be better as with component you have an extra digital to analog conversion because it has to be converted from digital to analog from the PS3 to your tv on component and then at the tv it has to be converted back to digital for deinterlacing at the tv, but again this isn't set in stone on which will be better. It depends on the circuitry of the tv.
I think you will be able to impact input lag much more by what type of post processing is going on at the tv level, advanced picture controls and all that entails.
If you are already in game mode then you should check your tv and see if any of your HDMI inputs are labled as PC inputs and try that as it tends to cut down on post processing.
The bottom line is like you have stated, since the tv has to both scale and deinterlace the PS2 games are notorious for this, any differences you are seeing are from your tv panel circuitry and how it handles the signal.

To combat this I have hooked up component cables, and when I play PS2 games I force 480i through display settings, as I understand this might help with the input lag, since the ps3 is no longer de-interlacing. The problem is, I have been so compulsive about this that I'm beginning to wonder if that helps the input lag or not; I'm driving myself crazy with it and I'm starting to wonder if the lag is still there through 480i component or if I'm just imagining it. Does anyone have any experience with this? |

Doing it at the player should cut down on input lag rather than doing it at the display. The same reason why many people who play fighters actually force 1080p at the PS3 rather than the tv because it reduces the input lag. They choose poor scaling at the PS3 for less input lag. I don't see how you would create more input lag at the player end.
I mean input lag is a delay between the signal being sent and your display showing that signal. When you scale or deinterlace at the player all of this is being done before the signal is sent. I don't understand how it would be worse unless it is your tvs specific interal circuitry and how it deals with the signal and that simply can't be changed.

I should have been more specific - HDMI through PS3 disallows 480i entirely in all cases, so all native 480i games are de-interlaced and up-scaled poorly by the PS3 itself, creating input lag (not to mention horrible artifacts and jagged edges). I have discussed this with others and tested this against a PS2 proper on length before with results confirming my suspicions (on my television). When hooking up through component the PS3 allows you to output 480i, and my question was simply does the 80gig PS3's software-driven PS2 emulation still create input lag, or was that simply a result of the de-interlacing of 480i games to progressive, be it 480p or 1080p. |
