It is still using nvapi, in the log you'll see lots of;
fixme:nvapi:unimplemented_stub function ...
You are adding deviceid and vendorid as strings, they need to be dwords, this
should work;
wine reg add "HKCU\\Software\\Wine\\Direct3D\\" /v VideoPciDeviceID /t
REG_DWORD /d 0x67df /f
wine reg add "HKCU\\Software\\Wine\\Direct3D\\" /v VideoPciVendorID /t
REG_DWORD /d 0x1002 /f

There's an alternative for the registry hack, start the game with "-GPUCount 1"
command line argument (yes, even if you have only one gpu).
But it may cause other problems problems. E.g. Settings -> Graphics -> Video
Memory always shows something like xxxx / 512 MB due to unimplmeneted
NvAPI_GPU_GetPhysicalFrameBufferSize. Probably best to use the registry hack
for now.
