Would it be possible to run two OSs simultaneously by hibernating one of the OSs?
the way i understand it hibernating an OS dumps ram to a file and powers off, so could it be possible to run two OSs "simultaneously" by alternating between hibernations?
Yes, this works. However, you can not (or should not if you possibly could?) modify data on partitions mounted by the hibernating OS. If E.g.Windows and Linux are installed and Windows is hibernating, the NTFS partitions can only be mounted read-only under Linux.
proton and wine are great but far from perfect.
i wanted to play a small indie game demo just a few days ago, installed it through proton and it didn't have audio. ran it through wine and that was even worse. the overhead of a vm is too much for my machine to run games well
If you tried running it outside steam through wine, you should try again using GloriousEggroll's wine instead of default.
Wine isn't really made for games and (iirc) doesn't include support for a lot of commonly used graphic/audio api's, which GE's version does.
Or if it is through steam and it still didn't work correctly, you could try his version of proton. It gets more frequent updates and some other fixes as well.
Or you really just found a game that doesn't work under proton, in which case you could open an issue so they can fix it at some point
