PS2 [Open PS2 Loader] Game Bug Reports

[Agrippa]

And if you record content shown at 50 fps, make sure to match your camera frame rate with it.

I could, but for me it already works perfectly, so I don't see the reason to waste HDD space

We aren't trying to figure out what's causing the micro-stutter, it is present in the og DVD as I said.

The problem is the stutter that happened to @Tupakaveli which I'm not longer able to reproduce.

...However I never tried to change DMA settings on GT4. I'll see if slowing down the DMA the stutter will reappear

 

[Grahf]

Nothing stutters from the original DVD, dude. If it really does for you, maybe your PS2 is having problems reading DVD9 games. It was very common on PS2.

Testing being the reason, you know.

 

[Peppe90]

WinHIIP INTENTIONALLY tries to fit games into some of the empty 'slots', when a game has been deleted 'in-between'!

WinHiip is able to make fragmented installations even with just formatted HDD.

@Grahf Sure your HDD is fragmented. I'm not saying that it is causing you problems. Maybe yes, maybe not.

Ah yes, I'm just waiting my Canon EOS C300 Mark II to arrive from China lol

Jokes aside, you're right. My phone is pretty old (Nokia 530), I thought to can catch the thing with it but I'm thinking it was better to not upload the videos...

I agree indeed. Anyway those video previews requires the pulldown 3:2 conversion, being recorded at 24 or 23,976fps as @TnA said

My Ps2s (I've 4 at the moment, tried GT4 with 3 of them) don't have nothing wrong, I Always saw this little stuttering in GT4 previews.
I remark this is not the problem. When you'll have the game you'll confirm from yourself

 

[Grahf]

I had the game in the past and there was no stutter in those vids.

 

[Peppe90]

It isn't a real stutter. You can notice the stutters in DVD films?? I think yes, but GT4 is even less noticeable.

Anyway I done things just a little better:

The stutter is really noticeable in the Nurburgring preview (since the first turn to the left)

The PAL version seems a little more blurred

EDIT This is just how things have to be. The problem is when this microstutter becomes much noticeable than that (it's like micro-freezes when it happens).

Are we even talking about the same things here?

The game itself has some FPS drops here and there and those videos were made from in-game graphics. However, there is some stuttering in the actual video playback from HDD. It doesn't run as smooth as it should. This happens to me with GT3 as well if I don't set the right DMA mode. It's probably because PD (the developers) used very high bitrate videos and they need perfectly smooth playback.

The one from preview video aren't fps drops. They're exactly the same as ntsc DVD pulldown stutter (PAL DVD doesn't stutter 'cause them are just accelerated to match 25fps). You know what I'm talking about?? If not, just ask or google for it, I'll not be repeating the same thing forever!

I think we can trust the @TnA experiment. I'll do it too, so I see if I can confirm that video previews run at 24hz.

 

[Grahf]

They are FPS drops of the game's graphics engine. The gameplay drops frames like that as well. GT4 is pushing the PS2 to its limits and it has been one of the major complaints about this instalment in the GT series. Its framerate is not as stable as in GT3. The videos were recorded from the in-game graphics and that's why that turn at Nürburgring doesn't look smooth. What I am talking about is that the video playback itself isn't perfect from the HDD for whatever reason.

We're not even talking about the same thing, as I had suspected from the start. *sigh*

Have you seen the Nurburgring preview on the PAL DVD version?? (PAL version is the first video), the stutter seems more noticeable then the usa version I'm running from HDD.
The stutter it's not continuous, previews are smooth most of the time. They stutters in quite precise points.

I can't find a video on YT to show you the pulldown effect… You can experience it if you have a Ps3/Ps4 just disabling the 24p output option, making sure your output is 60hz. You will see the pulldown stutter

I played GT4 almost throrougly when it comes out, I'm aware about frame-rate drops.

It's possible that video previews have been taken from game's footage, but your fps-drops theory is not standing.
Indeed there aren't fps drops when reproducing the same situation in game

 

[Grahf]

I told you from the start not to compare the NTSC and PAL version. They run at different scan rates.

Possible? It's obvious.

The videos were made from the in-game footage. That's why the video recorded actual FPS drops in the game, especially when taking that curve you were talking about. This is NOT what I am talking about. I am talking about the video playback. Stop with that pulldown talk because it has nothing to do with the problem here. The PAL version was obviously converted to 50 Hz, so that's what's causing the effect and it's typical in PAL games. What I am talking about from the start: the video playback is smoother from the original disc, so there is something wrong with that when this game is played from HDD, at least on some setups.

 

[Peppe90]

@Grahf Probably the Nurburgring preview stutter is more easilly noticeable on the NTSC version 'cause my phone recorded the video at 30fps, actually matching the game as @Agrippa was saying. Therefore this video is more faithful of what is happening on my tv.
I can assure you that the PAL version (from DVD) stutters exactly as the NTSC (from HDD).

I tried changing the DMA setting to MDMA 0, but the stutter doesn't increase.

 

[Peppe90]

Possible? It's bloody obvious.

Yes, Probably

The PAL version was obviously converted to 50 Hz, so that's what causing the effect and it's natural in PAL games. What I am talking about from the start the the video playback is smoother from the original disc, so there is something wrong with that along when this game is played from HDD.

You're talking without seeing. We'll talk about it again when you get the game

 

[Grahf]

I had the game in the past and I know how those videos play. I've seen those menus a ton.

Something is wrong with the video playback. Besides, as I've already told you, I have the same problem with the FMV playback in GT3, needing to adjust the DMA mode for them to play smoothly. There's some underlying issue here.

You could notice it only if you're really looking for it I too, never noticed it before, and I played the game as much as you at that time.

Are you talking about the GT3 video previews, the intro FMV, or both??

 

[jolek]

I was talking about the sound buzz. Maybe I could solve it on previous builds with only MDMA 0 due to differences between PAL/NTSC versions. I never used the Ps2 Logo simply 'cause for me, the faster the games boot, the better it is

The buzzing sound is present on both versions (PAL & NTSC).
MDMA, UDMA settings are blind spot because other devices will not use it.
It may only works for HDD.
Unfortunately it is not working with my config.
Other solution that works previously was cold boot -> E1 launch keys.
But I think currently this "method" is not working.
I can't find with what OPL rev this "solution" worked.

I rather enable PS2 logo, wait a bit longer to get rid of this annoying sound.

 

[Grahf]

All FMVs in the game.

How can you know how much I played it "at that time", lol? We're really talking about different things here. You refer to the actual video content, which isn't perfectly smooth because it's only a record of the in-game footage, which has framerate dips. I am referring to the actual video playback, which seems to have some stuttering from HDD, at least on some setups. There has to be some underlying issue here because I have the same problem with FMVs in GT3 (which are also of a very high bitrate, for PS2 standards).
