When completed your registry should look something like this. Then create a DWord Value named MSISupported and set its value to 1. You'll need to create the following regkey and sub-regkey, Interrupt Management -> MessageSignaledInterruptProperties. Under your GPU regkey, locate the Device Parameters key.

Locate your GPU regkey under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\ plus the Device instance path we found in Device Manager. GPU Device Instance PathĬopy or take note of the path (Yes I know its really, really long) and next open up regedit. In the Properties window, click on the Details tab and select Device instance path from the Property drop-down menu. Device Manager -> Display Adapters -> GPU

Once logged into your Windows VM, go to Control Panel -> Device Manager and open the Properties of your GPU under Display adapters. My gaming VM is running Windows 10, but this fix should work all the way back to Windows 7. Now it's time to login to the VM in question and apply a reghack that will enable MSI. If, however, you're fortunate enough to have a modern GPU with MSI support, you'll want to check if your GPU's Audio has MSI enabled.Īs you can see, both the Video & Audio portions of this NVIDIA GPU support MSI, but currently don't have MSI enabled. If you've discovered your GPU doesn't support MSI then you can stop reading and head to Amazon or NewEgg to order a new GPU. It's important that the VM you're passing your GPU to is running as MSI will always report as disabled when the VM is off. If you don't see MSI listed at all, that means you're out of luck and it may be time for an upgrade. MSI: Enable+, means MSI is already enabled for your GPU. If you see MSI: Enable-, that means your GPU supports MSI, but it currently isn't enabled. Look for the line that begins with Capabilities. With your VM running, you'll want to SSH to your unRAID server as root and run this command. Now this fix will only work for NVIDIA cards that support MSI or Message Signaled Interrupt.ĭoing the Same for your Audio Performance The problem was so severe that I couldn't even play Youtube videos on the VM.Īfter much research I found a Windows registry fix that seems to have made everything all better. This was very frustrating to say the least as gaming on my VM was effectively crippled. I would occassionally have some audio stuttering issues with unRAID 6.1, but never really saw any video problems until I upgraded to 6.2. Now the setup for GPU passthrough with unRAID is fairly straightforward, but one of the bugs that has become more noticable with version 6.2 and above is video and audio stuttering. Keep in mind that this isn't exclusive to unRAID and you can accomplish the same thing with QEMU on a standalone Linux box. Say bye-bye to virtual graphics that can barely run Minesweeper let alone Minecraft. This allows users to play the latest titles on a VM with little to no performance loss. One of the surprising features that led me to eventually purchase unRAID is the ability to passthrough NVIDIA GPU's to your VM.
Now I know that unRAID's bread and butter is functioning as a NAS, but in recent releases they've added a ton of features, one of them being VM hosting support via QEMU. This helps supports the channel and allows us to continue to make videos like this.I tried out unRAID last year as an alternative to VMWare vSphere because getting non-server hardware to work with vSphere is getting more difficult with each release. 🕹 Chat with me on Twitch (Live Streams) 🕹ĭISCLAIMER: This video and description contain affiliate links, which means that if you click on one of the product links, I’ll receive a small commission.
