I've been waiting for some time to be able to implement this, but finally was able to do it today. I needed to do the following:
1. Download a BIOS update for my 3080 graphics card (this was the last thing to become available, and was why I couldn't do it until recently).
2. Download a BIOS update for my motherboard.
3. After updating the motherboard's BIOS, go into the BIOS settings and turn on resizeable BAR.
What you need to do will depend on what graphics card and motherboard you have, and not all hardware can support it at all.
My framerate for the FH4 benchmark improved from 160fps to 176fps at 1440p Ultra with 8x MSAA.
Edit: I should add, it also requires a pretty recent Nvidia graphics driver, which I already had, but they only added support for it fairly recently, so if someone had an old driver, they'd need to update that as well.
