ProtonDB

What is Proton?
Proton is a new tool released by Valve Software that has been integrated with Steam Play to make playing Windows games on Linux as simple as hitting the Play button within Steam. Underneath the hood, Proton comprises other popular tools like Wine and DXVK among others that a gamer would otherwise have to install and maintain themselves. This greatly eases the burden for users to switch to Linux without having to learn the underlying systems or losing access to a large part of their library of games. Proton is still in its infancy so support is inconsistent, but regularly improving.

What is ProtonDB?
The goal of ProtonDB is to gather reports from other gamers as they test games with Proton on Linux and provide aggregate scores of how well games perform. A growing pool of suggestions provides tweaks that you can try to get games working while Proton continues development. In addition to this, you may explore the Steam game catalog on this site to browse and discover a wide range of titles that were previously unavailable for use on Linux.
