Installing PortProton (Using WINE Proton without STEAM) linux-gaming.ru
PortProton is a project that aims to make it easier for both novice and experienced users to run Windows games on Linux. The project aims to make the process of running games (and other software) as easy as possible, but at the same time provides flexible settings for experienced users.
Attention Official website of the project from September 2022: https://linux-gaming.ru. Any other site is fake!
