Hey @Josh.5,
first off.. awesome project this is perfect for a gaming system for my kid.. he got a chromebook from santa and I was looking for a system to have him still play proper games..
But that leads me to the problems I'm having: I know it's not really made for it yet I'm still trying to make it work... minecraft.. specifically modded. I got to a point where I am using flatpak to install PolyMC, with that I can command line start an instance and even connecting to a server which seems to work even in Steam (I can just add an external game and boom it's there) ...
Just it's so extremely slow.. it's got a beefy machine available, 6 cores with 6 HTs (it's an Epyc 7282), all the ram in the world (128Gb), a 1660Ti and it's on a NVME disk... so I can't imagine it's the machine.. could it be that docker's IO just doesn't like the amount of loading Modded Minecraft does? (tho a server runs fine, which I'd imagine has the same IO available to it)
Help me Josh-i-one-kenobi.. you're my only hope.
Oh and an issue I'm having is: It seems to ignore "NVIDIA_VISIBLE_DEVICES" I have 2 graphics cards in my server but only gave 1 card access to the docker (with the guid and all on capabilities) yet steam / minecraft seems to still recognize there's 2
