Announced in February 1997, N64.com (IGN) wrote the following...

The company has plans for at least three other Nintendo 64 titles to arrive in either late 1997 or early 1998. The second may be VR Golf. While Gremlin, in the UK, will most likely develop Actua Golf for N64, the game, when it arrives in the U.S., will appear as part of Interplay's Virtual series as VR Golf.

Details of the game are vague at present, but as with other VR sports games, it's likely the game will include multiple perspectives, will be polygonal in nature, and that characters will be motion-captured for fluid movement.
