Ok, so this is starting to look really really bad for NVIDIA graphic card users, especially on macOS Mojave. Month after month is passing and there's still no new NVIDIA Web Drivers yet.Nothing. You know what that means ? Any hackintosh user with NVIDIA graphic card is forced to use older os. High Sierra recommended. macOS Mojave is still lacking support for most popular NVIDIA graphic processors. Just follow that thread full of angry NVIDIA users. There's also some official statements:

Developers using Macs with NVIDIA graphics cards are reporting that after upgrading from 10.13 to 10.14 (Mojave) they are experiencing rendering regressions and slow performance. Apple fully controls drivers for Mac OS. But if Apple allows, our engineers are ready and eager to help Apple deliver great drivers for Mac OS 10.14 (Mojave).

It appears that it's dawn of NVIDIA in macOS. Really. If you're careful observer, you'll notice that Apple is forcing Radeon graphic cards and integrated graphics.

EDIT 1: At tonymacx86 they say that NVIDIA is actively working on new drivers.

I apologize for any inconvenience this may have caused. We are working on it and the drivers should be available at the earliest.

EDIT2: Still no drivers yet. Nvidia on macOS is dead.
