[Windows][Vulkan/D3D11][Graphic issue] GOD EATER BURST (NPJH50352)

[nassau-tk]

What happens?

At some talking scene the graphic will not appear correctly.
It's will happen Vulkan&D3D11.
Like below.

If drawing correctly is below.

This issue is occurs by decided timing.
Glitch=>Correctly=>Glitch=>Correctly...in the 1 talking scene.

Please see attached GEdump files.

"This GEdump is scene of the issue."
NPJH50352_NG_DUMP.zip

"This GEdump is same scene of correct drawing."
NPJH50352_Good_DUMP.zip

OpenGL is not happen the any issue.

D3D9 is not happen the same issue but some graphic is over light.
(Only Face?)

What should happen?

What hardware, operating system, and PPSSPP version? On desktop and mobile phone, GPU matters for graphical issues.

Please test newest version in https://buildbot.orphis.net/ppsspp/

PPSSPP Ver.：1.10.3-1608
OS：Windows10（64-bit）Japanese
CPU：Ryzen7 3800X（8-core）
GPU：RADEON RX5700XT
Resolution：2560×1440
RAM：32GB

This is another one that looks related to depth clamp.

That said, an interesting thing to potentially correlate with other issues: this has cull face enabled during the clamping. Maybe that interacts with the clamp/clipping it does in interesting ways.

496/2174 is the first problematic prim. If I flip from CW to CCW, it culls all triangles which are a strip. All depth values in this case are 6 digits and positive.

The draw here seems to be properly culled based on the rules noted in #12058 - all vertices are outside Z in the same direction.

Can you try adding this game to DisableAccurateDepth compatibility?

Added this game id here's the result using your dump.

@nassau-tk how about this now?

@nassau-tk how about this now?

Yes! These issue was solved!!
Tested on @1.12.3-1411-gb233c2c9a

Vulkan and D3D11 both!!
Thank you!!

Well, this is only solved for GPUs that have user culling (i.e. not Mali, etc.) or while using software transform. We do have other issues for that already, though. There are actually several issues still open that are solved for many, but not all, GPUs.

Mm, that's right. Let's keep it open.

This should at least now be resolved for devices with user culling OR (working) geometry shader support OR using software transform.
