Proton 8.0 expands Linux gaming with new game support and bug fixes for Steam Deck.
Valve's Proton 8.0 update adds support for 18 new Windows games on Linux, including Chex Quest HD, a remastered version of a 1996 CD-ROM game. Proton is a compatibility layer that allows Windows games to run on Linux-based operating systems, and the update requires a GPU with Vulkan 1.3 support. The update benefits the Steam Deck, but it's an open source tool that can be used on any Linux PC.
