Unlike the Pascal GPU Passthrough, AMD does not have VM-limiting drivers. Q35 seems to perform better most likely because of how it implements the PCI / PCIe ports rather, that it implements PCIe vs PCI

In my experience, the driver installation will stall (in some cases at 99%) and not complete. Though i440FX was perfectly fine for nVidia and Q35-5.1 was available, both seem to work until driver installation for the AMD cards. Not sure if this is strictly necessary, but the previous VM was built on 0.1.173, so it seemed like a good time to upgrade. Download the most recent VirtIO Drivers.I have been able to confirm most of the issues from a similar forum post on this topic.

I’ll update this post when I do get a chance to diagnose this.) We’ll talk through just the first part, since the latter will be obvious. (I haven’t been able to get this working quite yet with the AMD GPU Only configuration. 2) Reconfigure the VM to only have the GPU interface.

I highly recommend doing the configuration in two stages: 1) Create a VM with VNC + the GPU to install / configure the drivers, etc. That was of course the first clue 6.8 wasn’t going to work well. In 6.8 the RX 6800 showed up as “AMD Graphics Card” versus “AMD Radeon RX 6800/6800XT/6900XT”. This also changes the display of the new AMD cards, as they are now known and supported in Unraid. This will bring along an update to the latest LTS 5.10.x kernel, as well as new Q35 and i440FX versions to use for VMs, we’ll need these. Plug in the USB drive and then run the USB Creator. Next, download the USB Creator software from the Unraid Downloads page. Unraid is actually loaded into the system’s RAM during boot and runs from there, so there is very minimal boot disk IO. I was still running Unraid 6.8.3 at the beginning of this, so first things first, upgrade Unraid to 6.9 or higher. Clean out the contents of the drive and name it Unraid, this is going to be your boot drive. Combine this with the RX 6800s being quite new, there’s a few complications involved in getting Unraid AMD passthrough running. Unlike the nVidia GPUs, however, AMD’s have been previously plagued with a reset bug which requires rebooting the host OS when the guest is shutdown / booted up. Luckily, I was able to get my hands on an XFX Speedster XICK 319 Radeon RX 6800 Black from Best Buy with 10 windows open, wildly refreshing during Best Buy’s last restocking. However, really any GPU is hard to come by these days as we’re in the midst of a global silicon shortage. Given the 1080Ti’s performance, it’s actually quite difficult to beat it on any sort of budget. Though I would love to upgrade to a 30-series Ampere GPU, the new Navi AMD GPUs are actually better at traditional rasterization workloads (at least per dollar). However, after fiddling with some settings to make it not look like crap, it seems like either the CPU ( hopefully fixed here) or the current 1080Ti is holding it back. Recently, I tried my iRacing / NAS rig in VR with an Oculus Quest 2 that a friend of mine brought over. XFX Speedster XICK 319 Radeon RX 6800 Black
