Wuthering Waves (version 3.3) crashes when loading into the game with raytracing enabled.

Software information

Game is Wuthering Waves, as of the version 3.3 update raytracing broke in the game and launching the game with raytracing causes it to hang or crash (it crashes with proton 10.0-4 and with later versions of proton, like Proton 11 Beta it hangs).
Aside from my gpu being a AMD 7900XT I have a intel 13700K in my PC.

A notable item in the Proton 10 log is:

13578.999:0138:01e8:err:msvcrt:_wassert (L"!succ->pred_back_edge || succ->pred_back_edge == &entry",L"../src-vkd3d-proton/subprojects/dxil-spirv/cfg_structurizer.cpp",3045)

System information

  • GPU: 7900XT
  • Driver: Mesa RADV 26.0.6-2
  • Wine version: Proton 10.0-4
  • VKD3D-Proton version: Proton 10.0-4

Since it crashes in dxil-spirv, it's probably helpful if you could dump and attach the *.dxil shaders here using VKD3D_SHADER_DUMP_PATH=/some/existing/dir.

@mbriar should I dump with Proton 11 Beta or Proton 10.0-4?

RRabbyDevs 2026-05-03 github

actually ill just do both

Mmbriar 2026-05-03 github

It doesn't matter the dumped dxil shader don't change depending on proton/vkd3d-proton version.

proton10-shader-dump.tar.gz

Let me know if anything else is necessary, I'll respond as soon as I can.

Since theres a hang involved in this, should I do breadcrumbs debugging on it?

Reproduced the CFG failure. That's more than likely the root cause here, so you can hold off until that is fixed.

@RabbyDevs https://github.com/HansKristian-Work/vkd3d-proton/pull/2985 should resolve the crash/hang.
