Well, the older driver will not work properly since it does not support Metal. In High Sierra, we could use Sierra's drivers and would get a acceptable result with passable or almost minimum stutter and jagger on screen.
But for this update, does not matter if is the latest driver from High Sierra or Sierra since Mojave makes heavy use of metal. Nvidia, as already mentioned and stated, does not care enough to write new drivers as Macs come around. Even little fixes like changing a version name of the driver ( literally one line ), they last 1 or 2 weeks to update.
I wouldn't expect anything soon for Mojave. I'm ready to wait at least 3 months ( or even more ) for this update. And yes, I am waiting as much as you, because a made a mistake to buy a 1050 TI
