What are the best ways to run a game on sandboxed mode with only game HDD shared to it. There should not be network access for the game and there should be GPU (intel integrated) pass-through.
I have tried Gnome boxes, but GPU pass through is not working and checked distrobox, but that too shares HOME folder.
I’ve done this before by packaging it in a snap. No filesystem access except its own snap directory, no network access because I didn’t request it in the snapcraft.yaml, but yes GPU and audio access through the desktop plug.
