Does this work with IOMMU?

it would be at a low enough level to reprogram IOMMU unless a hypervisor will prevent it.

if you have a hypervisor you can prevent the other to do the dma freely in memory because u can use iommu and things like amd-vi to separate it good. but if you dont have the hv below it, any devices with dma can do the duty across entire ram.

Unknown, but there were a few obvious bios options I saw that are needed to make the kits performant with some systems.

I still find it absurd people would go that far to cheat at a game. =3

I guess it turns the cheating into its own meta-game!

True, but a blacklisted $5k GPU seems like a bit of a risk. =3
