GloriousEggroll announces new project to unify Proton runtimes
(files.catbox.moe)
https://github.com/GloriousEggroll/ULWGL
From the github:
WHAT DOES THIS MEAN FOR OTHER LAUNCHERS (lutris/bottles/heroic/legendary,etc):
- everyone can use + contribute to the same protonfixes, no more managing individual install scripts per launcher
- everyone can run their games through proton just like a native steam game
- no steam or steam binaries required
- a unified online database of game fixes (protonfixes)
Wine attempts to translate Windows calls into Linux, its developed by Codeweavers whose focus is/was application compatibility.
Valve took Wine and modify it to best support games, the result is called Proton. For example:
Someone built a library to convert DirectX 9-11 calls and turn them into Vulkan ones, it was written in C++ and is called DxVK.
Wine has strict rules on only C code and their directx library handles odd behaviour from old CAD applications.
Valve doesn't care about that, they care that the Wine DirectX library is slow and buggy and DxVK isn't. So they pull out Wines and use DxVK.
There are lots of smaller changes, these are 'Proton Fixes', sometimes Proton Fixes are passed on to Wine. Sometimes they can't but discussion happens and a Wine fix is developed.
Fairly accurate except that Wine predates Codeweavers. They do contribute to Wine but Codeweavers did not make Wine.
Codeweavers makes CrossOver, a paid product.
