Gran Turismo 4 reddish hue on certain screen transitions

[paokkerkir]

Hi guys, I have an issue that I cannot seem to find anyone else having with GT4 (all versions).

It happens every time at race start when the camera changes to my selected view, and in certain camera transitions in replay mode.

It looks like the last frame is blended with the next one but in purple for a second.

Please look at attached screenshots to get a better idea.

I have tried with all renderers, all settings toggled, without increasing the internal resolution, with/without cheats, with/without dithering, Normal and Full Clamping, Manual fixes, but whatever the case it still happens. I'm on the last nightly release.

Only with the software renderer this issue is eliminated. Surely there is a setting I'm missing or a specific hardware quirk?

Thanks for any help

In order to help you further with your problem, please make sure the following are all provided.

• Your hardware specs - CPU, Graphics Card, Memory, Operating System.
  
• The version of PCSX2 you are using.
  
• Any non default settings you are using, such as speed hacks or presets.
  
• Your GSdx graphics settings (a picture of the settings dialog is preferred)
  
• What games you are trying to play and if you are playing them from ISO or DVD.
  

Thank You.

PCSX2 v2.1.169
Intel Xeon 2698v3, GTX 1080, 128GB, Win11
Only Non-Default settings are: Optimal frame pacing, Enable Fast CDVD.

Graphics settings attached.

The above behavior as mentioned happens in Gran Turismo 4 PAL, NTSC, and Gran Turismo 4 Online Beta - all ISOs.

I have toggled every setting and all renderers in graphics in order to isolate the issue but was not able to find out something.

The only way the above behavior does not happen for me is to use the software renderer.

After some research it looks like the same bug as in the below thread:

This was apparently fixed back in 2023, maybe there is a regression made here?

Can you post a gs dump of the issue when it occurs?

Gs dumps attached.

Can be replicated at every race start.
