No acceleration GTS 450 - whatevergreen - mojave

Build:

CPU: i7 4790k

Mobo: ASUS ROG Maximus VII HERO

GPU: Asus GTS 450

RAM: HyperX Fury 8GB 1866MHz

​

I installed macOS Mojave 10.14.1 with no issues (and even updated to 10.14.2). But there is no acceleration on the graphics.

I installed using nv_disable=1. Once inside the OS, I tried installing nvidiagraphicsfixup(got no display output at all) and whatevergreen latest version with latest lilu (it kinds works). The screen looks crappy. I am able to run dual monitors no problem.

Note: I tried the kexts on separate installations and didn't mix anything at all.
