How Does Proton Affect Gaming on Linux and What Is it for Steam – Guide
Proton is a compatibility layer for Microsoft Windows games to run on Linux-based operating systems. Proton is developed by Valve in collaboration with developers CodeWeavers. It is a collection of software and libraries combined with a patched version of Wine to improve performance and compatibility with Windows games. Proton is designed for integration into the Steam client as “Steam Play”. It is officially distributed through the client, although third-party forks can be manually installed.
What is a proton compatibility layer?
First, to understand what Proton is, we need to understand two technologies, DirectX and Vulkan. Consider them a game driver. These are APIs for communicating with graphics cards on your computer. These are programming apps. While DirectX is a closed source API developed by Microsoft and Windows, Linux is using the open source Vulcan API. There are many other APIs such as OpenGL, but we will only focus on Vulkan and DirectX. As DirectX is one of the most well-known Windows and Windows-only APIs in the world, game developers are focused on DirectX game development. Proton comes in here, as Linux doesn’t run Windows games. Proton made by Valve is a new fork for translations from DirectX to Volcano, via libraries such as DXVK (DirectX over Volcano). Think so. Think so. Your DirectX graphics card is the subject of Games. DirectX collects and allocates game resources. DirectX contains Direct3D (which is responsible for rendering 3D graphics in applications). To convert these Direct3D calls into understandable volcanic calls, Proton uses libraries.
What can you play with Proton?
Proton’s 2018 release saw just 27 games. However, in three years, the list of supported games grew to around 16,000. Proton, however, is limited because games with built-in anti-cheat mechanisms cannot be played. Players cannot, as the name implies, cheat the mechanisms. Spiel companies have partnered with anti-cheating mechanisms to improve the spawning experience. Some of the popular anti-cheat providers are BattlEye and they are easy through Epic Games. To find out which games are currently being supported, go to the official ProtonDB website. Of the top 1000 games, over 77% of Proton can be played with over 21% Native (not Proton), 21% Platinum (out of the box), 56% Gold (running after tweak), 66% Silver and 71% Bronze (runs but crashes often).
