![]() If not, put it off till your next upgrade. If you have a reasonably new graphics card and your BIOS allows you to set an option named something similar to “VT-d” (Intel) or “AMD Virtualization” (AMD), you should be good to go. ![]() GPU passthrough relies on some specific virtualisation technologies, so you’ll need to make sure your hardware supports it. This is a long, detailed post, so here’s a table of contents for easy traversal: Reports I’ve heard indicate that this is only a problem on CounterStrike: Global Offensive servers (as of ), but it could potentially become an issue for other VAC-protected games in the future. WARNING: GPU passthrough and VAC: Competitive gamers playing on servers protected by Valve Anti-Cheat may want to think twice before setting something like this up as their primary gaming machine, as VAC may detect it’s running in a VM and ban you. Part 3 is a bit rarer: it contains a number of small, important things you’ll want to do post-setup to get everything working nicely so you can actually use your setup. Parts 1 and 2 detail getting passthrough and your VM setup, and are largely similar to the most popular guides already extant. I’ve also got some help and input from a couple friends and colleagues who’ve also set this up and had slightly different experiences with it. You’ll probably need to refer to them and others while setting this up, because what worked on my machine may not work on yours. ![]() Much of the guide to follow is paraphrased from other sources, to which links have been provided. It wasn’t completely straightforward, and I did experience a couple moments of despair where I thought some tiny but important feature or behaviour was impossibly incompatible with my setup, but ultimately I got everything working, to the point where I’m writing this guide to save others the same despair and frantic googling. ![]() That was a few months ago, and so far I’m very happy with the setup. Once I was sure that everything worked (a much quicker process than anticipated) I replaced that Windows install with a Windows VM and went full passthrough.įallout 4 below, screenfetch above, Synergy in control Luckily, I had a spare SSD I wasn’t using for much, so I was able to isolate an experimental passthrough Ubuntu install to that SSD without touching my Windows installation on my PC’s other SSD. GPU passthrough seemed like exactly what I needed. It’s also incredibly annoying when Windows 10 runs into a :( face BSOD 2 and decides to restart immediately, crashing my poor, innocent Ubuntu VM along with it – if there’s one thing you can say about most mainstream Linux distros, it’s that full system crashes don’t really happen. And while I enjoy plenty of Windows-only games and programs, I vastly prefer the heavily configurable and less opaque Linux way for doing everything outside of running those games and programs. This virtualised usage also meant that I couldn’t really use Linux to operate my PC: the VM only got started for programming tasks. But I could never get sound to work on my Ubuntu VMs and would often accidentally make the storage too small and have to go through the chore of extending vmdks. Virtualising Ubuntu on a Windows base improved on that by allowing the use of both operating systems simultaneously: I could put full-screen the Ubuntu VM on one of my monitors and use Windows programs on the other with only the occasional Ctrl-Alt breaking the flow. So at best you tend to spend a few weeks in Windows, a few weeks in Linux, and at worst you forget about one of the OSes entirely. If you’re on Ubuntu and want to play a game, or on Windows and want to do some programming, you have to stop, close everything you’re busy with, reboot the computer, choose the other option on your Grub screen, and then log in again. With dual-booting, the other OS on your system is a full reboot away. Neither of these approaches fully satisfied me. I’ve tried the obvious options: I dual-booted Windows and Ubuntu on my laptop for most of my university career, and more recently I’ve tried just running a Windows host with a virtualised Ubuntu in VMWare. ![]() GPU passthrough: gaming on Windows on Linux 8 September 2016įor a long time, I’ve been trying to figure out just how to get the best of both worlds in terms of running Windows and Ubuntu 1 on my desktop PC. ![]()
