Question about Progressive Mode

[Killerwatt]

Does anyone know whether or not playing GGAC in progressive mode (480p as opposed to 480i) causes lag? Does it have a noticeable effect if you play in 480p then play on 480i? I'd like to know since I've been playing in 480p at home on my HDTV but most tournaments run it on SDTVs at 480i resolution. Thanks.

I'm not entirely sure about using 480i versus 480p, but there isn't an HDTV on the market that doesn't induce lag right now. If you switch over to an SDTV it will be very noticeable if you're used to hitting FRCs regularly.

the reason most tournaments don't use progressive scan is because most crt tv's don't support it. 480i is the standard resolution supported by almost every crt tv released in an ntsc market (us, japan, etc), and likewise game consoles output at that resolution.

the only difference as far as the signal goes is that 480i is interlaced, which means that one half of the screen is drawn during the first half of a frame and the other half of the screen in the second. this explains it pretty well.

480p, on the other hand, is progressive. this means that instead of drawing each half of the screen separately, the whole screen is drawn at the beginning of the frame. the majority of crt tv's don't support progressive scan, sadly. monitors do, but that's a whole other bag of worms, especially as far as the ps2 is concerned.

so yeah, it's just a different signal. it doesn't lag and it doesn't change the speed at which you view the game; it's just a different way of creating the same image while making it look better.

i should note though that if you're playing on an lcd tv, you should always play in progressive scan. the reason for this is so that you can bypass the input lag caused by deinterlacing.
