Hello,    I'm running Primary GPU passthrough using Seabios after extracting my vbios from the card, it's working but I believe my performance issues could be fixed by OVMF amongst other things.   I've seen some threads suggesting that I may need an updated vbios for my card. Any suggestions?   It's this card. https://www.techpowerup.com/vgabios/124862/gigabyte-gtx670-2048-120708   From the page I've linked :  UEFI Supported - No   https://w
