Are previously downloaded Steam games transferable from Windows to Linux?
Are previously downloaded Steam games transferable from Windows to Linux?
I've backed up many of the Steam games I had installed in Windows. Am I able to use these on Linux or do I need to re-download them?
Yup, you'll be fine. If a game has a Linux version though, you'll still need to download some portion of it. By the way, just don't use NTFS to play on Linux.
In my experience it works perfectly fine as long as you perform the steps outlined here, as per Valve's official recommendation. The section about preventing read errors is particularly important, but the whole thing is worth a read.
Might be useful for dual-boot users or the people in transition, but doesn't worth the hassle for exclusive users. However it will still cause some problems one way or another because it's just a workaround.
Why not NTFS? Back when I used to dual-boot, I always used the NTFS on my shared games drive. Never had any problems, especially with ntfs-3g on Linux
It is possible that you didn't have problems but it has a huge potential for that. WINE uses Linux symlinks and that's the main reason why it's not a good idea using NTFS for that, since when you boot Windows it'll correct those files because Windows and Linux have different case-sensitivity. Basically Windows will corrupt those files and you will have problems regarding that. If you don't boot into Windows you probably won't have problems though. On the other hand if you don't boot into Windows, why use NTFS. :)
Most games were fine but some wouldn't even launch off of ntfs
Thanks. I don't mind dling some additional stuff I just would prefer to avoid the bulk of it.
No problem! By the way, if Linux version of a game is broken (you'll encounter those), or if you want to use Proton regardless, set a Proton version for that game before installing and you can restore your backup without downloading anything.
Most of them can be transferred over as is. For games that have a Linux version Steam will download the Linux stuff. But usually all the assets take up most of the space and those are normally shared between all versions of a game.
Thanks!
For proton games, yes. I still have some games in my old windows installation and they work just fine.
If you manually set your games to use proton, that will work for all of them. For the ones that have a native linux version, steam will detect that you have the windows version and download the extra files needed for the linux version automatically.
Thanks!
My uncertainty with copying a Windows install over to Linux has to do with proton/wine prefixes. From my understanding, when installing a game using proton it gets its own prefix installed along with it.
How does that work when copying a game over and adding a non-steam game to Steam? Does adding the exe to Steam create the prefix automatically?
The prefix is created on first run. The game files do not reside in the prefix.
Yes, steam will create a prefix for any game or exe that you add when you first launch it. That's why the first launch always takes a minute or two.
The same exe can be used by windows and proton, so having a dual-boot setup with all games on the windows partition is feasible.
But there's one very important thing about that: Turn off fast boot in windows before mounting the drive in linux, otherwise you will have to wait hours when booting windows the next time (which can't be cancelled because microsoft).
Yes they can be. However, if you want to use a compatibility layer with them like proton the game files have to be stored in exFat (Linux file system format) format. If you have them on a drive formatted for NTFS (windows file system format) the game won’t start and wont tell you why. Games with native versions will run fine from a NTFS partition.
@beesterman @lightnsfw What?!? I run games using proton on an NTFS partition just fine...
If you do this it's safer to use lowntfs-3g so everything is forced to lower case... And yes using a proper linux filesystem is way safer.
I'm guessing symlinking the compatdata folder to a Linux friendly filesystem, like Valve recommends here, would probably fix issues like that. I'm sure there must be edge cases but, in my admittedly not extensive experience, I haven't encountered any myself.
So currently my backups are on my media server which is ext4. These would be moved to my gaming system when I wanted to install them. I would just need to make sure that was formatted in exfat for this to work?
Sometimes running applications from NTFS will have issues so I recommend doing rsync to a Linux FS before running
