I've seen this issue occur in a number of games, but never to this degree. Usually in games like Ratchet: Deadlocked or Prince of Persia: Sands of Time, this issue can be corrected by playing around with the GS Hardware Hacks and enacting a Sprite Merge with a Half-Pixel Offset or something similar.

That said, those games usually only have a single artifact where the image separates/ghosts. As you can see from my screenshot, the image splits into 3 ghosts regardless of any movement. There are actually 4 ghosts, but the Half-Pixel Offset: Normal (Vertex) aligns 1 ghost with the rest of the image, so it only looks like 3. As others have tried, Sprite Merge/Align and Auto Flush do nothing to mitigate the other 3 ghosts.

Here are other scenarios I've tested which replicate the same issue:
  • Latest PCSX2 x32 Stable or x64 Nightly
  • Render API agnostic (D3D11/12, OpenGL, Vulkan or Software)
  • Cheats or no cheats
  • Render resolution/ratio agnostic (From PS2 Native 480 4:3 to 6x 2160 16:9)
  • A myriad of different configs I've not taken the time to properly document
I've read elsewhere that this is supposedly an archaic "bloom" effect present in the original release that has been made to look worse by rendering at a higher resolution than native. The issue is still present at native resolution 4:3, albeit much less noticeable. I've seen others articulate this issue over the years to no avail. Is there any possible fix for this issue? This is my first time posting here, so please let me know if there's any additional information I can provide.

Yes.

It's a bit more difficult to perceive due to the lower resolution, but the artifacts are very clearly still there.

Software 3D renderers on the stable release? or the software renderer on the nightly release?

Edit:
Tested the Stable release with OpenGL and D3D11 software renders. This was the product. Ghosting is still evident, it just gets clouded due to the loss of information. I will update this comment after I test the Nightly release's software render.

Edit 2:
Same effect as the stable release. Widescreen patch is applied to the above image, which is what is modifying the UI and compressing the gameplay. Regardless, the effect is still present.

I wonder if that effect isn't supposed to be here...
What if you try on your PS2 ?

I don't own a PS2 anymore. That's why I use an emulator lol.

Using a BIOS file with PCSX2 which you have downloaded from the internet or from a PS2 console you do not own is illegal. You must own the console the BIOS file came from (even if it's broken) to be legal.
