I have a desktop and a steam deck. I would like to setup some old games I have on disc on the desktop. Then compress them and decompress on my Steam Deck without doing the full install again. I understand that with wine/proton prefixes they should be installed to a “fake c:/ windows hierarchy” can I just compress that and copy to a different Linux machine? Does it save which proton version was used? If I use something like Lutris or bottles can I import into them?
What about graphics drivers? What if the desktop has an Nvidia GPU and the steam deck is AMD. Would that even matter?
No, you can copy wine prefixes around all you want. You may have to adjust the graphics settings in the games though.
Makes sense. I wouldn’t want to have all of my games in one wine prefix. I would like to keep them separate like steam/proton does. From looking it up, it seems the issue is that there is a lot of duplicate data that would need to be deduplicated. Steam supposedly does symlinks to solve this. But, if the symlinks points to /home/user/ as the base then that would break on /home/deck.
If you have any experience with Lutris/bottles. Do they do separate wine prefixes? If so, how do they handle it?
Lutris uses separate prefixes and doesn’t do any deduplication. You will need a separate tool for that or just use a filesystem like btrfs that supports deduplication.
I’ve never used bottles, so I don’t know how it handles deduplication.
Thanks for your help!
