Linux Mint vm problem - Running in software rendering mode, and GPU pass-through question

I am a total linux newb - no experience with linux at all. Also, it's been about only 3 weeks, since I started using unRAID. I am in the process of migrating files form my old windows server to unRAID atm.

• 1) I have installed a Linux Mint vm on unraid, and I always get this warning, after booting up the vm: Running in software rendering mode. I guess it's got a problem with GPU drivers? So how do I install the virtual gpu drivers? or is there something else needs to be done? As it is now - the vm is practically unusable. I have attached the screenshots of the warning and my Linux Mint vm settings in unRAID.

I would really like to be able to pass-through the gpu to a LibreELEC vm and use it as a Kodi player. Down below are my IOMMU details. It seems my GPU is not alone in the group. 

These are my PCI Devices and IOMMU Groups:

• 2) Would changing a PCIe slot on the mobo, that the GPU is plugged in have any effect on IOMMU grouping? I think that's a USB3 card in group 10, and it's alone. Would putting a gpu in that PCIe solve my issue?
• 3) If not, should I use the Enable PCIe ACS Override option? I am worried that it says right there in the info: Warning: Use of this setting could cause possible data corruption with certain hardware configurations.

Thanks in advance for any help.
