Hello @Jens14L, sorry, but all Terascale hardware does not support Vulkan, and the PROTON_USE_WINED3D runtime option is also not considered supported which makes your system unsupportable in general. For this issue to be evaluated on the game side, then you need to reproduce the issue with vanilla wine and report it to the upstream wine project.
That said, you've identified that your issue is a video driver regression and you should report that issue to your video driver vendor first.
