The Core Upgrades

Proton is the “secret sauce” of Steam Play, combining a heavily patched version of Wine with state-of-the-art graphics translation layers. The 10.0-3 release ensures all these moving parts are running the latest, most stable code:

VKD3D-Proton	Updated for more robust and faster Direct3D 12 rendering via Vulkan.
DXVK-NVAPI	Updated for better compatibility with NVIDIA-specific features and functions.

The Crew Motorfest
Mary Skelter: Nightmares
Fairy Fencer F Advent Dark Force
Grim Fandango Remastered (Improved on AMD & Intel GPUs)
