Nvidia GTX 970M + Nvidia drivers 381.22
[snip]
Tested with: [HKCU\Software\Wine\Direct3D] MaxVersionGL=0x00030002
You should not set MaxVersionGL when using proprietary Nvidia driver. If you really won't to set it use 0x00040005 in order to not limit OpenGL version.
A bit of an OT digression...
Eh, I don't think setting it to 0x00040005 would make any difference currently, wined3d is creating the GL context with the version set in gl_info->selected_gl_version, which is one of the supported_gl_versions[] elements i.e. version 3.2 at most.
This was intentional; we probably want to change it though. I can look into it.
