# Create the VkSurface on the first call to IDXGISwapChain::Present,

# Supported values: True, False

# dxgi.deferSurfaceCreation = False


# Enforce a stricter maximum frame latency. Overrides the application
# setting specified by calling IDXGIDevice::SetMaximumFrameLatency.
# Setting this to 0 will have no effect.
# 
# Supported values : 0 - 16

# dxgi.maxFrameLatency = 0


# Override PCI vendor and device IDs reported to the application. Can
# cause the app to adjust behaviour depending on the selected values.
#
# Supported values: Any four-digit hex number.

# Report Nvidia GPUs as AMD GPUs by default. This is enabled by default
# to work around issues with NVAPI, but may cause issues in some games.
#
# Supported values: True, False

# Override maximum amount of device memory and shared system memory
# reported to the application. This may fix texture streaming issues
# in games that do not support cards with large amounts of VRAM.
#
# Supported values: Any number in Megabytes.

# dxgi.maxDeviceMemory = 0
# dxgi.maxSharedMemory = 0


# Override back buffer count for the Vulkan swap chain.
# Setting this to 0 or less will have no effect.
#
# Supported values: Any number greater than or equal to 2.

# dxgi.numBackBuffers = 0


# Overrides synchronization interval (Vsync) for presentation.
# Setting this to 0 disables vertical synchronization entirely.

# image n times, and a negative value will have no effect.
#
# Supported values: Any non-negative number

# dxgi.syncInterval = -1


# Enables or dsables d3d10 support.
# 
# Supported values: True, False

# d3d10.enable = True


# Handle D3D11_MAP_FLAG_DO_NOT_WAIT correctly when D3D11DeviceContext::Map()

# games which do not expect Map() to return an error despite using the flag.
# 
# Supported values: True, False

# d3d11.allowMapFlagNoWait = False


# Performs range check on dynamically indexed constant buffers in shaders.
# This may be needed to work around a certain type of game bug, but may
# also introduce incorrect behaviour.
#
# Supported values: True, False

# Assume single-use mode for command lists created on deferred contexts.
# This may need to be disabled for some applications to avoid rendering
# issues, which may come at a significant performance cost.
#
# Supported values: True, False

# d3d11.dcSingleUseMode = True


# Override the maximum feature level that a D3D11 device can be created
# with. Setting this to a higher value may allow some applications to run
# that would otherwise fail to create a D3D11 device.

# improve performance in titles which overuse tessellation.
# 
# Supported values: Any number between 8 and 64

# d3d11.maxTessFactor = 0


# Enables relaxed pipeline barriers around UAV writes.
# 
# This may improve performance in some games, but may also introduce
# rendering issues. Please don't report bugs with the option enabled.
#
# Supported values: True, False

# d3d11.relaxedBarriers = False


# Overrides anisotropic filtering for all samplers. Set this to a positive
# value to enable AF for all samplers in the game, or to 0 in order to
# disable AF entirely. Negative values will have no effect.
# 
# Supported values: Any number between 0 and 16

# d3d11.samplerAnisotropy = -1


# Enables SM4-compliant division-by-zero behaviour. Enabling may reduce
# performance and / or cause issues in games that expect the default
# behaviour of Windows drivers, which also is not SM4-compliant.
#
# Supported values: True, False

# Clears workgroup memory in compute shaders to zero. Some games don't do
# this and rely on undefined behaviour. Enabling may reduce performance.
#
# Supported values: True, False

# d3d11.zeroWorkgroupMemory = False


# Sets number of pipeline compiler threads.
# 
# Supported values:
# - 0 to automatically determine the number of threads to use
# - any positive number to enforce the thread count

# dxvk.numCompilerThreads = 0


# Toggles raw SSBO usage.
# 
# Uses storage buffers to implement raw and structured buffer
# views. Enabled by default on hardware which has a storage
# buffer offset alignment requirement of 4 Bytes (e.g. AMD).
# Enabling this may improve performance, but is not safe on
# hardware with higher alignment requirements.
# 
# Supported values:
# - Auto: Don't change the default
# - True, False: Always enable / disable

# dxvk.useRawSsbo = Auto


# Toggles early discard.
# 
# Uses subgroup operations to determine whether it is safe to
# discard fragments before the end of a fragment shader. This
# is enabled by default on all drivers except RADV and Nvidia.
# Enabling this may improve or degrade performance depending
# on the game and hardware, or cause other issues.
# 
# Supported values:
# - Auto: Don't change the default
# - True, False: Always enable / disable

# dxvk.useEarlyDiscard = Auto
