# Enables frame rate limiter.
# The frame pacing is coordinated by Metal (w/ CoreAnimation)
# rather than simulated on CPU. Thus you will get a beautiful straight
# line for the frames time graph. However, the system may not provide
# the frame rate you'd requested, for example, you would get 30Hz if
# you request 40Hz on a 60Hz monitor.
#
# Supported values: Any non-negative integer, preferably a factor of 
# the monitor refresh rate

# d3d11.preferredMaxFrameRate = 60

# Adjust MetalFX Sptial Upscaling factor.
# It is multiplied by source output width & height to get the
# final output resolution. 
# e.g. To get 1440p from 1080p you only need a factor of 1.33
#
# `DXMT_METALFX_SPATIAL_SWAPCHAIN=1` environment variable MUST be
# set for this to take effect.
#
# Supported values: Any number greater than 1.0

# d3d11.metalSpatialUpscaleFactor = 2.0
