Plugin is in development, not fully ready yet.
There’s also the plugin “pause games” that can suspend a game, stopping it from having any CPU/GPU load while you play something else. However it doesn’t free up used memory, and sometimes controls don’t work when multiple games are open, with one game intercepting inputs meant for the other games. So this would be pretty cool if it works out.
I really hope that all the work that has been going into the process freeze/unfreeze functionality on Linux at some point leads to the ability to have universal save states for every game.
Would be so cool to just restore to one of the last savestates in any game, no matter how crappy the save system in the given game might be.
Sadly I don’t think that’s possible. Modern games are much larger and more complex than the traditional games that you could use save states in.
Not only would you need to save several gigs of RAM to disk, you also need to somehow capture the state of things like graphics cards and potentially the filesystem and other devices, none of which are trivial.
I’m fine if it works only with smaller/older/simpler games.
GPU is the reason CRIU can’t do it which is a shame…
It could potentially work like save states in emulators do. Even if its only a single state like on XBOX, it would be so good if this works reliably someday.
