It really depends whether he got the devs of "Lutris, Heroic, Legendary, Bottles, etc." to agree to use the unified runtime before starting this project. As long as he gets most of the big players to join then it will actually become the only standard worth using.
From the naming it's clear that GE wants this to be the new standard, but it's not really a new standard. This is porting Steam's launcher, which already exists, to non-Steam clients.
Unification of standards only works if everyone agrees to use it and only it (i.e. mobile phones and USB C), otherwise you're just adding another one to the pile.
This is a bigger issue for hardware than software. This is why we can use heroic, proton, lutris, or whatever. And most programmers who can offload a part of their code onto another project that is doing the job well will. That's exactly how Linux started.
My worry is Valve will look at the project and shut it down. Remember, Valve doesn’t care about your Linux, it only cares about money. Not having users on their Client side platform means less revenue and less ads to show.
This is great. Proton is getting a lot of testing just based on Steam's userbase and it is backed by Valve. We also have a lot of data on proton's performance and potential game-specific fixes in the form of protondb. Making sure that non-Steam launchers can use all that work and information is crucial to guaranteeing the long-term health of linux gaming. Otherwise it is easy to imagine a future where proton is doing great but the other launchers are keep running into problems and are eventually abandoned.
One thing that I am curious is how this handles the AppId. If this AppId is used to figure out which game-specific fixes are needed, then it will have to be known. Do we have a tool/database that figures out the AppId from the game you are launching outside of Steam?
I hope it makes pirated games easier to launch on Linux. 👍 I've got about 5 different games I've yet to play cos I can't be arsed looking into Proton command line flags.
Given Proton can actually be faster on some windows games, there might be a legitimate use case for this.
It would also be useful for developers to use for testing. Low friction access to a Linux runtime environment would make it a lot more reasonable for Devs to support Linux as well.
That's mostly down to DXVK, not Proton in general. You can't really translate Windows API calls from Windows to ... Windows. It wouldn't change anything. Running games with Vulkan might though, especially with Intel Arc for example.
Sounds like this would be easier to setup and use than Lutris though - dunno about everyone else but I'm always so very confused trying to get non-steam games running on linux, with all the custom paths, simulated folder structures and prefixes while steam apparently does it on its own out of the box.
