I play games regularly, and the sad reality is that it forces me to use Windows on my desktop. There's a Linux installation on there, but rebooting into it is such a massive interruption that I usually just move over to my laptop for programming. Working on a laptop leads to all sorts of ergonomic issues, and it felt like a massive waste to not develop on the desktop hardware I invested so much in. So after extensively researching what the VFIO community has been doing, I've deleted my Windows installation and moved all my gaming into a virtual machine on a Linux host.

Normally VMs are too slow for gaming, but thanks to a feature called VFIO you can run games at near-native performance by passing graphics cards and USB controllers directly to a virtual machine. The only requirement is that your board supports IOMMU, which most modern systems have. In this guide I'll wal
