Armored Core 2: Floating/misplaced shadows

[Helium-4]

PCSX2 version:
v1.5.0-dev-2334-gefc1274b2

PCSX2 options:
Default

Plugins used:
Default

Description of the issue:
Shadows often are misplaced or appear wrong, especially when moving near some pieces of geometry, in a few area they even float above you, standing directly below a piece of geometry can sometimes lead to your shadow being projected above you instead of below you.

This problem also partially affects the other Armored Core games (up to Silent Line at-the very least) but in a much lesser way.

How to reproduce the issue:
1.Start a new game
2.Go near geometry and run against it, functional doors especially

Last known version to work:
None

PC specifications:
Intel i7 4770K
Nvidia GTX 1070 (390.77)
Windows 7.

EDIT: Still present and completely unchanged in v1.7.0-dev-332-g271bec0f1

Does this happen in both HW and SW renderer? It could just be how the game handles shadows, there's always edge cases where they won't cast on the correct plane 😛

[Helium-4]

It does happen in both renderer, but the first issue does not happen on real hardware (I pretty much checked everything I submitted against a real hardware play through I did alongside.), the second one I'm not 100% positive because it only triggers that badly in one specific case and I forgot to retest it exactly in the same conditions before putting my PS2 back in storage.

@Helium-4 is this still an issue in current master?

[Helium-4]

Yes

Can you provide a savestate using the latest master please? Also make sure your pad plugin is lilypad, else I'm gonna have problems :P

Thanks for the savestates :) I checked some stuff out, it isn't what I was hoping it was so I'm kinda stumped :( Hopefully we can find out what it is at some point. No settings seem to affect it either.

Tested the scene of first pic on v1.7.4338, it looks still same as well.
Here are my GS dumps and Savestate:

Is this still a thing on the latest nightly + could anyone post pictures straight from ps2 for comparison sake? Not a single person on this thread posted how this is suppose to look correctly lol

Replicated on real hardware. Not an emulation issue.
