Here's a small maintenance update for you!

New Features

• the toggle key can now be changed with e.g. toggleKey = F1 in the config file
• added the image sharpening filter that's used by nvidia

Build

• adopted meson as the new build system
• shaders will now be included in the main binary
• most headers are now included in the source to avoid version mismatch (looking at you, arch)
• fixed building with clang and gcc10

Bug Fixes

• floats in the config file will now be parsed locale independent
• fixed crash when a option was present in the config file but had the wrong format

Misc

• deband is now deprecated because the reshade shader works better, it might be removed in a future version
• renamed the layer to VK_LAYER_VKBASALT_post_processing to be more conformant with Khronos standards
• updated the reshade compiler to 4.7 including support for new primitive types
• upgraded Vulkan layer version to 1.2
• more possible locations for config files have been added
• it's now possible to use "quotes with white space" in the config, this should be useful for filenames
• there will be no prebuild packages because of dependency and install issues on different distros

🐸 🐸

New Features

• applied effects can now be toggled on and off with the HOME key
• the amount of debug output can now be controlled with the new Logger

see the README for more info

Misc

• updated reshade shader compiler
• fixed potaintal issues if the game uses the newer vkGetDeviceQueue2 function

Known Issues

• amdvlk-pro will have issues with some reshade shaders, this is a bug in their shader compiler

🐸 🐸

New Features

• vkBasalt can now use a big number of reshade fx shaders, please read the README for more infos
• FXAA quality has been improved by always applying the changes in the sRGB color space
• VK_KHR_swapchain_mutable_format is now used for sRGB <-> UNORM format conversion if available
• Vulkan 1.0 applications are now getting promoted to Vulkan 1.1 to increase compatibility with newer features

Setup

• GCC 9 or higher is now required to build vkBasalt
• the config file doesn't get overwritten by updating/reinstalling vkBasalt anymore
• the config file can now be located in ~/.config
• Vulkan 1.1 is now required

Bug Fixes

• broken behavior caused by the application requesting the swapchain images more than once has been fixed → improved compatibility with mesa overlay and mango hud
• lut effect no longer leaks memory
• swapchain recreation no longer leaks memory

Misc

• added FAQ section to the README, please read it!

Acknowledgements

• @crosire for creating ReShade and helping me with the shader compiler
• VKx discord for helping me with testing and finding driver bugs
• mesa devs for implementing VK_KHR_swapchain_mutable_format in mesa 20 after my request

New Features

• added 3D color LookUp Table effect

New Features

• added Deband/Dithering effect
• SMAA settings can be change in the config file
• performance may has improve a little bit since settings are now applied at pipeline creation

Setup changes

Build

• GCC 7 or higher is now required

Shader Directory

The directory all spir-v shaders will be read from can now be in the following locations:

• a directory set with VKBASALT_SHADER_PATH=/path/to/vkBasalt/shader environment variable
• the old shader folder $HOME/.local/share/vkBasalt/shader/ or $XDG_DATA_HOME/vkBasalt/shader/
• /usr/share/vkBasalt/shader
• /usr/local/share/vkBasalt/shader

This should help distribution specific packages.

Config File

The config file will now be searched for in the following locations:

• a file set with the environment variableVKBASALT_CONFIG_FILE=/path/to/vkBasalt.conf
• vkBasalt.conf in the working directory of the game
• $XDG_DATA_HOME/vkBasalt/vkBasalt.conf or ~/.local/share/vkBasalt/vkBasalt.conf if XDG_DATA_HOME is not set
• /usr/share/vkBasalt/vkBasalt.conf
• /usr/local/share/vkBasalt/vkBasalt.conf

Bug fixes

• SMAA should handle sRGB correct
• CAS should now look much better since some typos from the port to glsl have been fixed

New Features

Enhanced Subpixel Morphological Anti-Aliasing

• Higher quality anti-aliasing than FXAA
• Can be enabled in the config file

Option to use multiple effects at once

• Can be configured via the effects option in the config file

One environment variable to rule them all

• 32-bit vkBasalt can now be enabled with ENABLE_VKBASALT instead of ENABLE_VKBASALT32

Config file

• The config file now allows white space
• It is now possible to change settings like subpixel Anti-Aliasing strength for FXAA

Bug fixes

• Presenting from a compute queue should no longer cause artifacts
• Memory allocation an intel and amdvlk should be fixed
• VkInstance and VkDevice objects are now destroyed properly

New Features

Fast Approximate Anti-Aliasing

• Can be enabled in the config file
  Note: Currently, enabling FXAA disables Contrast Adaptive Sharpening

zlib License

• vkBasalt is now licensed under the zlib
• if a previous contributor has issues with this change, contact me

Bug fixes

• sRGB should now be handled correctly
• reads and writes now happen to separate images, this fixes undefined behavior and artifacts
• vkBasalt can now be used together with other layers like the validation layers

New Feature: config files
-added option to choose the sharpening strength
-global config file in ~/.local/share/vkBasalt/vkBasalt.conf
-local config files named vkBasalt.conf in the current working directory will be preferred over the global config file

Bug Fixes:
The layer has Synchronization thanks to @doitsujin .
This should mean vkBasalt works in games which present from compute.

Known Issues:
-games which use sRGB-Images may be darker or not work at all

Fixes the return handling of vkBasalt_QueuePresentKHR. This should mean less crashes and frozen screens.
Thanks to @doitsujin

fixed crashes on some amd cards.
