rjorgenson Posted September 15, 2020 Share Posted September 15, 2020 I have an Asus Prime x370 Pro(latest BIOS, 5603) with a Ryzen 1700X, GTX 1080, and a Samsung 960 Pro NVMe SSD that I am currently running windows on. I am attempting to run unRAID on this system and virtualize my windows system(for gaming) so I can consolidate my computers down a bit. I am also currently acquiring parts to upgrade this host to a Ryzen 3900XT on x570 a bit down the line (or maybe Ryzen 4000, or 5000? who knows). I put unRAID 6.9 beta25 on a thumb drive and am giving this a go to see how well it might or might not work before migrating all my unRAID stuff from my actual server to this new one. So far I am having terrible lag and stuttering on the VM when gaming, though it seems to run pretty much okay for normal desktop stuff(web browser, video playback, etc). Here is how I have my VM setup. Host passthrough on the last 4 CPU cores and their threads(8 total, all isolated in unraid settings) emulatorpin set to the first core and it's thread 8G of memory for initial and max (I initially tried 16G as I have it to spare but read that more can cause issues so I tried with less) i440fx-5.0 OVMF hyper-v off (nvidia card) passing in my game storage drive via /dev/disk/by-id with SATA driver passing through my GTX 1080 with ROM BIOS from techpowerup and hex edited (only GPU in system) bother motherboard and GPU sound cards being passed through bridged networking stubbed (via vfio plugin) NVMe samsung 960 pro (it's in it's own IOMMU group) USB mouse dongle (wireless) USB keyboard (wired) Here is a list of the things I have tried, all with no success. cpu isolation/pinning (with 4 core and their threads[8 total] as well as 3 cores and their threads) emulatorpin setting motherbaord audio only graphics card audio only no audio at all passing just the NVMe drive and not the storage drive rebuilt the machine using q35-5.0 instead of i440fx-5.0 installed a completely new instance of windows 10 to a vdisk not passing through any drives various permutations of CPU cores/pinning/isolation I am at a complete loss as to what to try next. I am hoping someone can point me in the right direction every thread i've found so far has been a dead end =/ Any help would be greatly appreciated! As far as testing goes i've been using latencymon(seeing interrupt to process latency up to 71416 microseconds and DPC routine execution time as high as 30911 microseconds) as well as just firing up a game and seeing how it plays.
