I do not have firsthand experience, but have read about it in a few places.
For some reason, Ryzen/AMD appears to tank framerates unless you disable NPT (Nested Page Tables).
Disabling it, though, degrades CPU performance; the extent of which seems to vary on who you ask.
We've only got a few places it's referenced, but the story is still fairly similar all around.
It's been posted on this thread, at reddit (twice), and on the VFIO mailing list with no response.
Hopefully a less harmful workaround than disabling NPT is found; the second reddit post looks interesting.
How did i miss this within this thread. Ugh. Thank you for this information. I'm going to try and give it a whirl tonight, see what my results are. I'll report back when i have anything meaningful.

So has anyone who has bought the Ryzen chip had any good luck in terms of playing games at around 60 fps? At the moment games just jump all over the place from a steady fps down to the 10-20 fps. Portal and Portal 2 work like a charm, but any game like dying light, witcher 3, borderlands, or anything with some extra umph seems to go all over the place in terms of performance. Running on 3d Mark had no issues. I'm at a bit of a loss on what to do.
I've changed the minimum cpu frequency to match the max to try and reduce any latency that may be causing any issues, changed some performance metrics, etc. I'm not sure on where else to go from here.
I'm loving everything else about unraid, just this last hump i'm trying to get over and this system will be great. Any and all help will be appreciative! -

Picking the right motherboard helps, and using AMD graphics seems to make the process a bit easier and perhaps cheaper, though you can go nVidia too, just with a bit more work to do the BIOS passthrough. If you use HDMI sound passthrough that seems to alleviate much of the issues of bad IOMMU groups on sound devices and crackling on USB sound, but it seems there are solutions for both of those issues as well, all described in this thread.
I haven't tried this myself, still testing up-time with Global C-state Control disabled. Today I reached 14 days of uptime.

For all those who are interested in using Nvidia cards, spaceinvader one on youtube did release a new way where you don't need a second gpu any further. The files from techpowerup will work just fine now. What the files had were special headers for Nvidia flashing cards. The youtube video goes through a guide on opening up a Hex editor to remove all the unnecessary junk so you can pass through the vm. This saved me a bit of frustration as my first attempt i somehow created a blank bios dump.
Congrats on the long up time!

Some combination of spiking to very low framerates and/or very low resource (both cpu and GPU) utilization with low framerates as well, but yeah, this isn't consistent enough to have traced yet... I've actually been leaning to there being something about Dirextx 11 that messes with performance on VMs?
I've been having some of these issues as well where the fps changes all over the place. Tested on two different games. First game I tested was Portal 1, smooth gaming experience. Next game I tried was Borderlands the Presequel and had dips and changes quite often. Moved the game to the cache drive I have installed and still had same issues. Thought cache drive may fix it, but that wasn't the case. Changed resolutions as well hoping that would fix it and didn't. I game on a 2k ultrawide monitor. Has this ever been a problem with the Intel boards?
Post Edit:
Display Port/HDMI sound passthrough works. Never looked too much into getting the sound card on the motherboard to work as I finally found what was causing the issue I believe. Changed the cpu cores from 0-7 to instead use the cpu cores 8-15 for the windows vm. Playing around with dockers and haven't had any issues. Only one so far i've really dedicated too any time is Plex. -
Finally have my unRaid system up and going. I have a MSI X370 GAMING PRO CARBON motherboard with an AMD 1700x. Currently only have an 8tb HDD with a 1 TB cache drive. I'm willing to dump any information that is needed to put together a data base of useful info.
I finally have a windows 10 VM up and running. Nice and smooth for the most part, but video and audio seem to be the issue. I'm passing through a gtx 1080 for audio and video. Going to play around with combinations of whether its the audio passthrough for hdmi causing issue, as well as try through the motherboard. If anyone has any information to pass my way to pinpoint it, i'd greatly appreciate it. I'll be poking around in the mean time. -
Hi everyone,
I've been lurking on unRaid and reading up as much as I can. I've been wanting a storage solution for a while and when I came across unraid I was pleasantly surprised with all the features. Was very hesitant at first about waiting for more Ryzen support or tackling head on. From everything that i've read, I decided to invest into AMD and help out Pauven with his stakes in it!
I purchased the MSI X370 GAMING PRO CARBON, mainly for the m.2 drives. Eventually i'll be going into that as my cache drives. Initially i'll only be having one data drive and one cache drive with gpu pass through for some gaming, then eventually expanding my storage.
Looking forward to troubleshooting with the community in making unraid a killer option for Ryzen. Once I have everything set up, i'll be more active within the community.For all those who have put in the hard work before myself and others jumping in, thanks!
Anybody planning a Ryzen build?

If you're concerned with how to passthrough the gpu, I would look up spaceinvader one's youtube tutorial on it. I linked it earlier in this threat. No longer do you need two gpu's to do passthroughs. You'll still need another computer to edit a hex file.
I was able to get mine up and running without any issues. I am using cpu cores 8-15, it should be the same since you're on the 1700 and i'm using a 1700x. 30GB virtual hard drive, 10 gb of ram (there is a bare minimum of at least 2), stored within the domains folder that unraid creates for VM's. Are you still having issues setting up a vm?
I'm still having issues getting to turn off npt tables. I found an older discussion lime tech (https://goo.gl/4aRAoL), but it doesn't seem i'm making any good changes. Even looking up else where. I'm most likely doing it incorrectly as even if I have it set the npt to 0 or 1, game's still have some issues. Were you able to have any success phbigred?
