Symptoms

Winterbottom has two paths, a D3D10 path and a D3D9 path. With the current Proton build, the game picks D3D10 but immediately hits a snag with Effects:

wine: Call from 0x7b43c6bd to unimplemented function d3dx10_43.dll.D3DX10CreateEffectFromResourceW, aborting

This is unimplemented in both Wine and DXVK. AFAIK D3D9 should work just fine, as the Effects for 9 are just SpriteBatch-like shaders and Wine's current implementation should be able to handle it. (And if not, this may be a good time to look at my implementation in MojoShader...)

Note that the game uses XACT for audio; this is known to work with FAudio but may not work with stock Wine.

Reproduction

1. Boot game
2. Wait
3. Read logs

Start with steam-40930.log and the reported D3DX10CreateEffectFromResourceW failure. Compare the game's D3D10 and D3D9 paths, including the noted XACT/FAudio dependency, and verify whether the D3D9 path works. Done means the game starts without the reported Effects failure and its compatibility behavior is documented.
