Are you able to create a GS dump in roughly the same location but in hardware mode (so the issue isn't there) and upload it here?

[GitHubProUser67]

Yes of course, I did the next best thing, and took 2 GSdumps at the same place, one with software, the other with hardware :

I managed to find the exact same place and position you are, and mine looks like this:

Here it is a single frame gs dump if it helps: Test Drive Unlimited_SLUS-21490_20240822020642.gs.zip

and a save state file, if can help too: texture test drive save state.zip

Mine is SLUS-21490, Idk if this interfere some way or a lot.
