There's a guest-adjustable override for the Direct3D video memory using 
the registry key:

HKEY_CURRENT_USER\Software\Wine\Direct3D\VideoMemorySize  (in MB, 
text-mode key).

More similar details can be found in function wined3d_dll_init() in

I haven't found out much more about this.
It must have to do with the host-guest GL communication, I think.
