To answer your two additional questions: "when starting the VM Windows reports most of the ram is taken (over 95% of 10GB), but it doesn't show what is using it, is that normal?" Yes, this is normal behavior of UnRaid, the VM will use however much ram you have allocated to it in the settings, if you want to see specifically what is using ram you can use top or htop in the terminal. "what does setting the GPU bios in VM options do?" The primary use for setting the GPU bios is to allow resetting of Nvidia GPUs for unraid upon boot. Also certain GPUs may require having a bios file selected to work at all.

I finally figured it out. For anyone else who may run into this problem and has tried everything they can think of, remove the Vbios file in your VM settings. You will suddenly find performance is much closer to what it should be.

Hey everyone, I have been using unraid for a month or so now and I absolutely love it, however I do have one nagging issue. I am getting REALLY poor performance in games on a Linux guest system with Ubuntu-Mate 18.04.1. I have no idea why, my Windows VM on the same machine performs flawlessly. Specs are as follows: Dell Precision T5500 with dual Xeon X5680 CPUs 36 GB DDR3 ECC Memory EVGA Nvidia GeForce GTX 970 The video card works and is properly set up with correct drivers, ect. I have tried damn near everything I can think of to get better performance, including switching between Q35 and i440FX, enabling/disabling hyperthreading, changing the number of CPU cores for the VM, and I have tried various versions of the Nvidia driver as well. As far as I can tell, performance in games is about half of what it should be. I am getting 30 FPS in games like GRID: Autosport. A game which I know for a fact ran at 60 FPS (or more) when I was running it on bare metal. If anyone has any idea what I can do, please let me know. Thank you
