# dxgi.enableHDR = True
# Allows the Vulkan driver to opt-in to exclusive full-screen mode on
# Windows. Certain features, such as variable refresh rate or HDR, will
# not work without this setting, however enabling it will break certain
# games that use additional GDI windows, and it will also break alt+tab.
#
# This setting has no effect on non-Windows platforms.
#
# Supported values: True, False
# dxvk.allowFse = False
# Enables Unreal Engine 4 HDR workarounds for games that do not follow
# the standard -Win64-Shipping.exe naming scheme. May be needed to avoid
# crashes in D3D11 games on HDR-enabled systems due to statically linked
