--- Comment #2 from Henri Verbeet  ---
Windows file handling APIs (like fopen() and CreateFile()) are supposed to be
able to handle slashes as separators, and VKD3D_SHADER_DUMP_PATH is indeed
working for me with the bundled vkd3d. (And I tried a couple of different
variants to be sure.)

Chances are that the issue you're seeing is slightly more subtle than described
here. What is the specific path you're setting VKD3D_SHADER_DUMP_PATH to? Can
this be reproduced with either of (the Windows builds of) the vkd3d demos
"vkd3d-gears" and "vkd3d-triangle", or does this issue only occur in specific
applications?
