I just wanted to say this thread sent me on a dark path I had been planning for a while but finally made me pull the trigger I also have been wanting to switch to Linux full time, really the only thing holding me back was multi-boxing. I tried the Wine path but ultimately decided I could not live without ISBoxer. I had been dual booting for a while but I have finally gotten around to running Linux as my primary and I am running a VM of Windows 10 for WoW/ISBoxer. I am directly passing my 2080Ti and 9 of my 12 cores (18/24 with threads) to the VM. One nice thing is video card also has built in USB C so I bought a USB c to USB 3.0 hub and I can hang my headphones from that for sound. I am using evdev to pass my keyboard and mouse through but I think I am going to end up with a KVM for that just so I can run the native software. I bumped my system RAM up to 64Gb and I am passing 32 to Windows. I have not booted back to full Windows to verify but I believe I am getting close to 80-90% native performance in my VM. Scoring 6226 with Cinibench 20, 4880/4275 sequential in CrystalDiskMark (qemu RAW file on NVMe drive.) This is with no overclocking and no performance tweaks yet. I have a second smaller NVMe I was thinking of passing through and installing Windows directly on the drive but I don't think the performance would be any better.
