Ah yes, after trial and error, 3 takes recording this, I finally got my Windows virtual machine to take the AMD GPU with PCI passthrough. These are the steps I took and the guide I followed. This guide should work for both AMD and NVIDIA dedicated graphics cards. NOTE: If you're using an AMD GPU you may run into some issues as I did. For me the fix was disabling CMS in the bios. Also IOMMU needs to be enabled in bios no matter your hardware. 📖RESOURCES AND MENTIONS Guide*: *There are some additional steps and information in this video that are not included in the guide. Primarily during the VM setup process because of minor changes with Windows 11.
