d3d11: Chained Echoes: broken / flickering shadows
Just tested with the dxvk-master-e9ad90562cf4f785f33038bd27bc8c58f5222008 Github Actions artifact and the shadows are still broken.
Hi there and thank you for the issue.
If able then try to get a apitrace of the game. Also attach log output.
Not seeing any issues when running the game locally, probably an Intel driver issue.
(or missing information on how to actually reproduce the problem)
@doitsujin, yeah it's probably an Intel issue... I'll try getting the logs that @Blisto91 requested, but other than using Mesa 25.2.6, Wine 10.17 and opening the game with overrides for d3d dll needed for DXVK, everything is set at their defaults. I don't have any weird / exotic setup going on here.
Should I open an issue with Mesa?
Update: I just tried playing with MESA_LOADER_DRIVER_OVERRIDE=zink with WineD3D, to test anv instead of iris and the game plays fine...
I don't think this is an Intel driver issue.
WineD3D with MESA_LOADER_DRIVER_OVERRIDE=zink:
I'll try updating to Wine 10.18 and see if that helps.
Updating wine isn't going to do anything. Keep in mind that running wined3d through zink isn't equivalent to running dxvk from a driver point of view (nevermind the fact that wined3d also has a Vulkan backend now that can be used with WINE_D3D_CONFIG="renderer=vulkan").
If this is somehow supposed to be an actual DXVK bug then I need instructions on what exactly to do in game and which settings / resolution to use in order to reproduce the issue. Just by running around on the ship after starting a new game doesn't trigger it here at least.
Okay. Using GALLIUM_HUD=fps shows that I'm using iris with WineD3D, so I don't think I'm using the Vulkan backend. My display is 3840x2160 / 60 Hz. All that is needed to trigger this issue for me is to launch the game and, without changing any in-game settings, start a new game and immediately the screen flickers from the shadowed areas seeming to work right and then going black. Sometimes I need to move the character for it to happen, but other times it flickers immediately upon starting a new game. I'll try getting an apitrace (I'll need to read up on how to do that first). I've attached the terminal output, if that helps.
I'm having trouble getting the apitrace. The game immediately crashes after copying the d3d11, dxgi and dxgitrace DLLs from the apitrace-13.0-win64.7z into the game directory. I double checked that the game executable was 64bit with file ./"Chained Echoes.exe".
Attached is the Wine Debugger log.
Edit: I also tried launching apitrace.exe with wine apitrace.exe trace -a dxgi "Z:\mnt\ramdisk\chained_echoes\Chained Echoes.exe" but the game still crashes. I' not sure how to proceed here.
I manage to get the apitraces for the game. One for the beginning of the game and the other in the middle of the later chapter. https://drive.google.com/file/d/1wMKa9NWXikZbySSljcNtjuWoB2SK-yIv/view?usp=sharing
Thank you! After testing more games, I now believe that this is more of an issue with ANV and not DXVK.
EDIT: I just retested on both 2.7.1 stable and the latest github actions master build and this no longer happens in the latest Chained Echoes release from GOGs. I am using CachyOS with mesa-git, so it seems this is fixed for D3D11 titles. However, I do still get random black flickering textures with D3D8 games like Unreal II or with D7VK and D3D6/7 games but setting d3d9.ffUbershaderVS = False fixes that for me. The random black textures doesn't happen with my AMD RX 7600, only on the Intel iGPU. So clearly an ANV bug.

When using DXVK 2.7.1 with the GOG version of Chained Echos, the shadows are broken and flicker while moving around. When using WineD3D they render correctly.
