Gran Turismo 4 progressive scan issues

[FinnishFish]

So, I feel like I am beating a dead horse, but I can't find anyone with this same issue. In Gran Turismo 4 (SCUS-97328) on the nightly 1.7 releases, on Windows and Linux, the in game setting to set the resolution to 480p will not stick between restarts of the game. I don't think this has anything to do with the pcsx2 settings unless its something to do with how the game saves or something. Its pretty darn annoying to have to go in and change a setting in game if you don't want the game to be looking like a blurry mess.

Steps to reproduce:
Enable "show resolution" in the OSD
Boot the game and start a race, OSD should say interlaced
Go in the in game settings and set the resolution to 480p
Start another race and the OSD will say 480p
Save the game and restart it
Start another race and progressive scan will not show up in the OSD, it will stay on interlaced like the menus

Expected result:
Resolution should be saved with the save game like with all the other settings.

Unless I am totally misunderstanding and it is normal behavior, but it sucks either way... So I only see 2 solutions here, get progressive scan to stick or force progressive another way.

I have spent the night trying to get no interlace patches to work, but I have no clue what I am doing. I tried just throwing in the below patch from the no interlace patch thread, but it would just make the screen shake or cause horizontal black lines, but then I changed it to this and set deinterlacing to automatic and maybe it did something??

Its still not a totally clear image, but I feel like I can make out distant turns without them being obscured by a interlaced mirage. OSD still reports it as interlaced, so I know the patch isn't forcing the mode.

Anyone have any better ideas?

That's the intended way. GT4's 480p/1080i mode won't activate until you entered the gameplay.

You misunderstand, I know it is supposed to only be progressive in races. My issue is that if I want to race with progressive scan I have to enable the setting every time I start the emulator.

[BloodRaynare]

Ah I see now. Unfortunately I think that also was the intended way. I booted it on my PS2 and yep it reverts back to "Normal" even when I saved it after and then rebooted the game.

Thanks for checking that. Boy, thats annoying and a very odd limitation. And I am assuming GT4 on console doesn't automatically set to 480p if it is set in the bios?

Any other good way to force progressive. Unfortunately deinterlacing does not look as good as progressive scan.

Probably Polyphony set it that way so people with standard CRT TV w/ composite cable could still access the menu without it blackscreened/no signal'd on them. But it was annoying indeed and even don't make sense since the 480p/1080i won't active until you enter the race anyway.

And PS2 has no way to set output modes in the BIOS unlike Xbox.
