Valve literally runs the proton development team lmao. It’s a downstream of wine with lots of additions like dxvk which translates GPU instructions from DX to Vulkan. Without proton, wine would be like a solid several years behind. All open source of course, so feel free to pull request or fork (which many people have).
I would bet actual money that the Switch 2 will be less powerful than the current Steam Deck. Nintendo is really good at making low powered handhelds. The Switch was the first Nintendo handheld that actually used any serious hardware.
The current switch is highly customized for Nintendo’s design and game development. It absolutely struggles to even emulate GameCube games because it doesn’t have enough juice to run anything besides native Switch games.
Steam Deck on the other hand has more than enough power to comfortably emulate Switch games, and easily any older consoles. Additionally, linux has been shown to run both native and windows games better than windows.
Wine Is Not an Emulator. All it has to do is translate APIs for windows only games, not emulate a whole windows machine. It is extremely effective, which allows Linux to provide equivalent if not better game performance.
Valve cares a lot more about making all games accessible to their customers and allowing the community to participate in modding. Nintendo cares a lot more about making AAA games and protecting their IPs. They are almost complete opposites in the video game industry lol.
No one in Valve works in Proton’s development. You can’t lie your way out of GitHub contributions history, you can see it and i can see it.
