Gigabyte X470/ X570 Aorus BIOS mod thread

The Resizable BAR DXE driver worked as intended.

Still not as pretty as having the option from Gigabyte unlocked in UEFI, but it does the job.

So my Intel Arc GPU is not stuttering like crazy any more (I mean it still has micro-stutters left, but this is what I get with Intel Arc I suppose).

Just move the option above the suppress if function, simples. And again, you never needed to enable ReBAR, Above 4G Decoding does exactly the same thing - allows the CPU to have full access to the GPU memory in addressable space. If enabling 4G Decoding didn’t do much for you then that would be a GB issue, most likely where they broke the option.
