# Enable Vulkan library.
# DXVK is a Vulkan-based compatibility layer for Direct3D 11.
# It allows running 3D applications on Linux using Wine.
# To fully leverage the DXVK, you need the following:
# 1. Vulkan library installed;
# 2. Capable GPU that supports Vulkan;
# 3. Latest GPU drivers which support Vulkan;
