I Tried Gaming on a Virtual Machine (Windows on Linux)

Can you actually play games on Windows inside Linux without dual-booting?
I tested GPU passthrough on CachyOS and tried real gaming with minimal issues.

In this video, I install Windows in a virtual machine on Linux using full GPU passthrough (RTX 3070) and test how usable it really is for gaming.
What I cover:
Problems faced while setting up GPU passthrough
VM configuration and PCI device isolation
Windows running through Looking Glass
Installing and playing games inside the Windows VM
Audio, latency, and stability issues
Is this a real alternative to dual booting?

System setup:
Host OS: CachyOS Linux
GPU Passthrough via VFIO : RTX 3070
Windows VM with dedicated GPU : GTX 1660 Super

If you’re a Linux user who still needs Windows for gaming, this setup might surprise you.
