Might be working now, oddly I thought I used the format modules-load=
and no luck but it is at the moment. Only issue, when I rebooted I had
to reset my dual monitor config. Any issues with kernel modules listing
other drivers, or is the only thing that matters the kernel driver in use?

My grub line :
"GRUB_CMDLINE_LINUX_DEFAULT="rd.modules-load=vfio-pci quiet
intel_iommu=on,igfx_off pcie_acs_override=downstream" (igfx_off is
because i cannot boot otherwise, got some graphic glitch at boot,
if you don't have it feel, free to remove itr"
Don't forget to update grub afterwards. It is weird though,
rd.modules-load is on others tutorials but not on arch wiki.
I believe that was the issue i had when first trying to get vfio
to grab the device on antergos first time i wanted to do this.

To start I am now running Arch with the VFIO kernel, I did
not compile with the i915, my machine failed to boot with
that last time. Currently I can't seem to get VFIO to
claim the devices I want to pass-through. You can see
kernel driver is still nvidia. I added my configs below.
I even tried a script. Every time I modify
mkinitcpio.conf I regenerate my intramfd with mkinitcpio
-p linux-vfio
What am I missing?

You're applying Fedora instructions to Arch, rd.driver.pre
apparently doesn't do anything on Arch. Look in the archive
for the past couple weeks, I believe there are some working
instructions there.
