+# My gpu passthrough vm powered by a Nvidia Geforce GT 1030
+
+This document describes how I managed to get my gpu passthrough vm up and running for gaming purposes.
+
+I took most of knowledge from the Arch Linux wiki article on [PCI passthrough via OVMF](https://wiki.archlinux.org/title/PCI_passthrough_via_OVMF) and from [SomeOrdinaryGamers](https://www.youtube.com/user/SomeOrdinaryGamers) [video](https://www.youtube.com/watch?v=h7SG7ccjn-g&t=1677s) how he built the "poor shamed computer" and managed to get it all running with no complications.
