It is enough, provided that you have your system configured correctly. Which, in this case, is designating a graphics card to use. Without that it defaults to using CPU rendering.
Most people don’t want to deal with the headache of configuring their systems and would rather use something more automatic.
That’s what Proton does for you. If you’re using Proton then it can assumed that you’re gaming and so defaults can be set to support that.
Whereas people use Vulkan for many different projects and so it chooses safe defaults and depends on further configuration by the user (which Proton does for you).
Native Linux games work just fine (I play native Rimworld every week or so), you just have to configure your system manually.
Or just use the preferred method of running Windows games via Proton. You’re going to be doing it anyway in order to game on Linux and so it is often more work to run the native version than it is to run the Windows version and let Proton handle the automatic configuration.
I’m confused. Shouldn’t me downloading the native Linux factorio and native Linux Steam be enough? Why would it default to something else?
