> I shopped around for computer parts with complete IOMMU support just so I could map the discrete GPU to the virtual machine and achieve near native performance... So just any standard/decent motherboard bought within the last 3-4 years? > I wish they'd make it more virtualization friendly. Which games do you have issues with when virtualizing? I've only been locked out of Halo Infinite and I enable all hyperv flags in libvirt. > Just yet another reminder not to "buy" games on these platforms, I guess. If you buy a game on Steam and you're unable to play it they'll refund you straight away, which is why everyone loves Valve and Steam even when the client is crappy. I couldn't be happier with my setup, which I assume is similar to yours. (2 GPUs)

> So just any standard/decent motherboard bought within the last 3-4 years? It isn't at all obvious that IOMMU is supported by even current top of the line motherboards. I looked at a lot of products and have yet to see the VT-d and AMD-Vi keywords mentioned in technical specifications. To confirm support I had to read their UEFI firmware manuals and look for instructions on toggling the virtualization support. https://pcpartpicker.com/forums/topic/466120-ecc-ram-and-iommu-motherboard-support https://pcpartpicker.com/forums/topic/466120-ecc-ram-and-iom... At least ECC memory support has started to show up in technical specifications. Looks like IOMMU is not quite there yet. > Which games do you have issues with when virtualizing? From what I'm reading many games take virtualization as evidence of cheating and have no regard for false positives. I'm currently assuming any game with battleye or easy anti cheat will issue permanent bans on virtualization detection. > If you buy a game on Steam and you're unable to play it they'll refund you straight away Somehow that doesn't bring me much peace of mind.

  I guess I'm just lucky, because I've had one MSI and two ASUS boards with this setup without issues, I guess it isn't listed everywhere, my strategy of just buying boards hoping it works seems to be the way! > From what I'm reading many games take virtualization as evidence of cheating and have no regard for false positives There's a lot of misinformation on the internet, I haven't heard about any cheats used in the wild using a VM and haven't had issues. >> If you buy a game on Steam and you're unable to play it they'll refund you straight away > Somehow that doesn't bring me much peace of mind. If zero risk purchases doesn't bring you peace of mind I recommend dual booting or running two rigs instead of using bleeding edge technology
