Proton is based on Wine (Wine Is Not an Emulator, the compatibility layer capable of running Windows applications on several POSIX-compliant operating systems) and includes additional components like DXVK (Vulkan-based D3D11 and D3D10 implementation for Linux), a library that translates Direct3D calls to Vulkan on-the-fly.
