ReShade 4.5.0 brings improved Vulkan and DirectX 12 support, and much more

Popular graphics modding tool ReShade received the latest update version 4.5.0 yesterday. As expected, it has a ton of changes, with perhaps the highlight being improved support for the newer APIs, especially Vulkan.

The new version also brings improvements to the GUI, effect compiler and Vulkan backend implementation, as well as improved depth buffer detection in DirectX 9 and DirectX12.

Alongside these, the new update adds several other changes which have been listed below:

Rework depth buffer detection code for all APIs again (They are now more similar, including more options for OpenGL)

Switched to using SPIR-V for shaders in OpenGL 4.6 for better performance (this needs recent drivers to work correctly)

Added UI widgets for preprocessor definitions to variable list

Added compiler error when passing a r-value to an out parameter of a function

Added compiler error when pass is missing shader functions

Added shader signature verification to effect compiler

Added support for assignment chains to ReShade FX (e.g. "a = b = c = 0;")

Added adjustment buttons to combo box widget and label to radio button list

Added option to show only specific color components in texture preview

Added context menu to technique list to edit included files in addition to the main source file

Added support for texture pooling via "pooled" annotation

Example:
texture MyTex1 { Width = 100; Height = 100; Format = RGBA8; };
texture MyTex2 { Width = 100; Height = 100; Format = RGBA8; };

ReShade will now attempt to re-use the same memory for textures with the same dimensions and format if the pooled annotation is set. This works across effect files too.

Added "ui_text" annotation for uniform variables to display custom text above the variable widget (refer to the image below)

Added support for GPU timings in Vulkan

Added environment variable to override path ReShade should load the next DLL from
You can now set "RESHADE_MODULE_PATH_OVERRIDE" to a directory for ReShade to load the next DLL, so you can chain ReShade with other injectors

Added OpenGL version information to log

Improved compiler error recovery for parsing errors in function parameter list and annotations

Improved Vulkan command buffer management (which improves performance)

Improved multi-threading of effect loading

Changed setup tool to install global Vulkan layer while it is open (fixes issues with RDR2)

Changed setup tool to use .NET framework 4.5 again for backwards compatibility

Changed texture preview to be hidden when effects are disabled

Changed COM reference counting behavior to better match COM requirements

Change default preset path to executable directory for Vulkan compatibility

Fixed memory leak in Vulkan (which worsened every frame)

Fixed depth buffer detection in Vulkan

Fixed setup tool not updating search paths to absolute paths in Vulkan

Fixed HLSL compiler error for variables that are named "Technique" or "Pass"

Fixed effect compile error with "discard" statement as last statement in a function with a return value

Fixed effect compiler error in pass definition not causing effect compile to fail

Fixed effect compiler error when multiple casts are chained in an expression

Fixed annotation assignments not supporting literal expressions (you can now write stuff like "")

Fixed effect compiler sometimes reporting duplicated syntax errors

Fixed crash in effect compiler when encountering an undeclared identifier in a shader pass state

Fixed empty preprocessor macros not being evaluated correctly

Fixed GLSL code generation for matrix indexing

Fixed GLSL code generation for vertex shaders with a return semantic

Fixed GLSL code generation for some component-wise operations

Fixed GLSL code generation for entry points with underscores in the name

Fixed GLSL code generation for boolean values in index expressions

Fixed GLSL code generation for arithmetic with matrices that are not floating point

Fixed D3D10/11 depth stencil view creation failing in some games (e.g. ArmA 3)

Fixed OpenGL depth texture creation failing for games using format "GL_DEPTH_COMPONENT" (e.g. Mugen 1.1)

Fixed OpenGL states not being restored during texture upload, which caused texture artifacts in some games

Fixed crash if "wglMakeCurrent" was called on an OpenGL context that was not hooked

Fixed access to textures in vertex shaders in D3D9 (limited to 4 bindings though)

Fixed "UseAspectRatioHeuristics" option not being stored in config file in D3D9

Fixed wrong color write mask when there is more than one render target in D3D9

Fixed Vulkan performance mode using wrong values

Fixed current depth stencil inheritance in D3D12 buffer detection

Fixed shared textures being deleted prematurely if a single effect is unloaded

Fixed preset switching always falling back to DLL directory for next preset

Fixed position of slider buttons

Fixed slider buttons being able to change value outside valid range due to floating-point precision errors

Fixed splash bar no longer appearing on reload after reloading a single effect

Fixed scaling up the font size causing cropping some buttons and the display of textures on the statistics page

Removed format filtering from depth buffer detection

Removed tutorial skip button for all but the first tutorial step
