How to "tell" Preview to use pcie gpu? I always had Intel gpu disabled.
You need to enable IGPU but set your external graphics card as primary in your motherboar's BIOS so Preview and hardware acceleration will work.

This doesn't solve the hardware acceleration issue so it's better to enable IGPU to get hardware acceleration. NoVPAJep is for motherboards without IGPU.
In my case, was the only procedure that solved the preview problem, even with iGPU enabled.

It's a common issue that Mojave breaks the preview of .jpg files. Install and inject the last version of Lilu.kext and NoVPAJpeg.kext inside your kext folder, and reboot, preview should be back working normally.

This helped. Already had Lilu, added novpajpeg and Preview now works.
I wasn't aware of this issue, because I replace a Nvidia for amd card just before update to Mojave. Thank you all for help.

No I noticed funny font, already applied terminal command "defaults write -g CGFontRenderingFontSmoothingDisabled -bool NO" but can't see improvement (same) compared to High Sierra. Monitor is 1920x1200 (non-retina).

Hi BillG66.
can you tell me which kext did you load ?
do you had any prob with your rx580 ?
does acceleration works ?

Many thanks in advance
Fabrizio
No, I haven't had any problems with my RX 580... I'm quite pleased with it. And, yes, I have acceleration.

As for kexts:

In clover/kexts/other, I just have:

FakeSMC.kext (version 6.26-322-g1b20eab7.1765)

In Library/Extensions, I have:

AppleALC.kext 1.3.2
Lilu.kext 1.2.8
NoVPAJpeg.kext 2.0
USBInjectAll.kext 0.6.4 (with a custom ssdt)
WhateverGreen.kext 1.2.4

Hope that helps!
