I was under the impression that the GPU couldn’t be used for Apps either, I’m totally down to skip the VMs and mess with that with HyperV.

For example, when I installed Plex from the apps section, my GPU wasn’t available to use for encoding. Maybe I missed something…

From my understanding, it isn’t so much Windows or GTA5 and more like car vs bicycle. If I can virtualize the NAS within Proxmox and use my 1080 for other things then my usecase is supported, having Truenas use the 1080 only for the host is non-viable for me.

Interesting, thank you for the rundown! It sounds like I may be better off running with Proxmox? Assuming I go down that route, would I go with TrueNAS Core instead?
