The game crashes on start, works fine with WineD3D and d3d8to9 + dxvk. May need msvcp70,msvcr70=n overrides to start properly with latest Wine.

The game now starts up fine with d8vk 0.10 🎉 , but there are some missing textures in game. I'll record a relevant trace shortly.

Edit: I've replaced the initial trace with one that reproduces the problem (same link will work). There are a lot of memcpy: dest buffer overflow warnings when playing back the trace, so not sure what is going on there, but it doesn't look good...

The textures could be due to it trying to CopyRects from MANAGED to DEFAULT which is not implemented yet.

Not sure what is going on with the vertex buffers though lol

The underlying problem is with whatever the game is using to render terrain shadows (namely of trees and other non-movable objects, since dynamic object shadows will behave correctly).

Disabling all shadows fixes the problem, while enabling any type of shadows (even spot shadows) will make it manifest.
