When Proton was brand new I remember Okami being among one of the first titles I tried to run, but never to any success. I’m happy to say that has changed, at least with Proton 5.0 hard at work. The only problem I’ve found with it is a random crash that can occur at anytime during any particular cutscene, and given that you have to manually save at certain locations this can be a little annoying if you’ve covered a lot of ground and barely made it to a save point before crashing. Still, it’s much further along than it was when Proton was in its infancy.
Now that I know how well it performs on my desktop I’ll have to install it on the laptop to see how Proton handles the game on an NVidia GPU… because science!
