Hey there. This might not be the right place for this discussion, sorry ahead of time. I wasn’t sure how to fit it in. Please accept my apologies for any grammar or spelling mistakes—I’m still learning English. My computer is getting pretty slow lately; some GPU ports are no longer working and I can only use half of the mainboard USB connections anymore. Performance in new games is dropping fast. It’s time for a fresh PC—especially if I want to enjoy ray tracing and other features. But what about the operating system? I used Fedora Linux for about a year before switching back to Windows 10 a few months ago. Fedora with Gnome felt much more natural; I really enjoyed the shortcuts and the overall feel. The downsides are real: some software isn’t available, certain games can’t be emulated with Wine because of issues with AC implementations, and Nvidia drivers kept pushing my limits. That’s why I went back to Windows 10 for now. Now I’m thinking about a new setup—new ideas needed. Basically, I want to install Proxmox on this PC. Spin up a Nobara VM and a Windows 11 VM. Assign the graphics card output to the Nobara VM, dedicate a GPU to the Windows 11 VM. Only configure Proxmox through the web interface moving forward. Setup Passtrough for all USB and PCIe devices (like Streamdeck, sound cards, Scarlett Solo 3) on the Nobara VM. Use Looking Glass to stream games or apps from my Windows machine to the Nobara system (I know Moonlight/Sunshine works, but Sunshine isn’t compatible with Valorant yet). I’d wake the Win-VM over WOL or whatever Proxmox offers, and run a custom client on it for specific apps so I don’t have to use it as a full VM—like a modified terminal server. Questions / sanity checks: Are there any major issues I’m missing? This should work in theory, right? From what I’ve read, it might add around 20ms latency and reduce performance by about 10% to 15%, depending on several factors. Any other significant drawbacks? Have others tried something similar? How does it actually perform? Thanks a lot! First edit: Proxmox is still flexible; I’m also exploring other hypervisors like Unraid.

I think you're complicating things by introducing Proxmox. A simpler approach would be using Nobara as your host OS and managing the Windows VM with virt-manager, which relies on QEMU and LibVirt. I currently run Ubuntu as my host system and use virt-manager for my Windows VM that includes a NVIDIA 1080TI passthrough. My configuration is more involved because I also added a NVIDIA 1050TI for the host OS, which required some challenges with the drivers but now functions smoothly.

I agree with your assessment. The main goal was to deploy a few lightweight VMs for home automation and background synchronization. By now, everything runs smoothly on a single Raspberry Pi 4, which is much more efficient. It looks like experimenting with virt-manager helped me avoid detection by most anti-cheat systems, though Vanguard AC still poses a challenge—probably I’ll need to dual boot if it becomes bypassable again. Thanks for the insight!
