trying to debug ray tracing dragon dogma 2

[andrew-ld]

hello, i'm trying to debug a gpu page fault that happens when activating ray tracing on dragon dogma 2, however by activating qa checks i can't compile a shader, i don't know how to continue debugging

Software information

game: dragon dogma 2

i am using amdgpu pro vulkan driver because radv driver have a lot of crashes (latest mesa commit) even without ray tracing, amdvlk is stable but gives less fps than amdgpu pro

System information

• GPU: 7900xtx
• Driver: pro
• Wine version: proton ge 9.0-5 + vkd3d compiled with qa checks
• VKD3D-Proton version: f7289b7

VKD3D_DEBUG=trace VKD3D_LOG_FILE="/home/andrew/dd2-debug/log.txt" VKD3D_SHADER_DUMP_PATH="/home/andrew/dd2-debug/debug/" VKD3D_CONFIG="dxr,descriptor_qa_checks" MANGOHUD_CONFIG="no_display,fps_limit=48,fps_limit_method=early,fps_sampling_period=333,vsync" vk_pro gamemoderun mangohud %command%

I tried using radv instead of amdvlk/pro and it seems to compile, I played for a while and some faults were logged by vkd3d.

shaders with faults: https://github.com/user-attachments/files/15537081/shaders-with-fault.zip

i dont find in shaders directory c73feef558c73116 and daf3394534fa70c

[andrew-ld]

anyway I forgot to specify that to enable ray tracing you have to edit the dragon dogma 2 binary or hide on wine the symbol wine_get_version

you can simply bypass it by doing

sed -i “s/wine_get_version/win3_get_version/g” DD2.exe

Could you try running with https://github.com/HansKristian-Work/vkd3d-proton/tree/dd2-heap-robustness-hack? Maybe it'll workaround the hang.

it still crashes after few minutes
