This latest update to the Proton 5.0 series, which in turn is based on the Wine 5.0 stable code-base, has continued performance enhancements, work around the Denuvo digital rights management, and also pulling in the latest DXVK. DXVK 1.5.5 was released at the end of February with Direct3D 9 additions, various D3D10/D3D11 fixes benefiting an assortment of games, and other corrections for this Direct3D-over-Vulkan implementation.

Proton 5.0-4 pulling in DXVK 1.5.5 is significant enough but there is now also a fix for Denuvo DRM failures hitting games like Batman: Arkham Knight and Just Cause 3, fixed mouse cursor behavior for Ryse: Sone of Rome, and improved game launch times. The performance improvements are for when emulating display resolution changes and for titles like Monster Hunter World.
