However, there are some things worth considering.&lt;p&gt;For one, the frame relay program will need to start in your guest before Looking Glass can connect. Last I checked the best you can do is have it start at login, so you need autologin to have a somewhat seamless setup.&lt;p&gt;Secondly, the cursor is sent through using the SPICE protocol, which is convenient. Unfortunately Looking Glass has no support for also handling audio, and no intent to merge such functionality in the future. So if you want audio, you’ll have to set up Qemu to forward audio directly to the host.&lt;p&gt;Finally, GPU passthrough setups is the thing that sold me on NixOS. If you’re a fairly experienced Linux user, setting up this complicated and multifaceted setup in a mostly reproducible way using a single file of configuration is pretty pleasing. Most of my configuration was this:&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;gist.github.com&amp;#x2F;jchv&amp;#x2F;b0e4b39679e450536a17cc6a5d69169a&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;gist.github.com&amp;#x2F;jchv&amp;#x2F;b0e4b39679e450536a17cc6a5d69169...&lt;/a&gt;&lt;p&gt;Really, all you need is to substitute the right IDs and it should practically work anywhere, all you have to do is setup a VM with the requirements met (UEFI, PCI-e device passthrough, Looking Glass device attached, and KVM FR server running) and run Looking Glass.&lt;p&gt;Ultimately, I dropped Looking Glass and GPU passthrough. It was a little cumbersome and performance wasn’t perfect. I ran GPU passthrough on a physical monitor for a little while, and then dropped it entirely after finding out that Steam Proton and Wine actually covered all of my bases anyways.</text></comment>

I&amp;#x27;m considering installing Windows 10 in a guest VM so I can run a few modern games that do poorly under Steam &amp;#x2F; Proton.&lt;p&gt;Anyone suggestions for good sources of info regarding which software stacks (e.g., Ubuntu 19.10 + VMWare) are likely to provide a good experience? Graphics performance matters.&lt;p&gt;I&amp;#x27;m unwilling to run Windows 10 as the &lt;i&gt;host&lt;/i&gt; OS because of personal feelings about telemetry.</text></comment>
