ReShade GUI

Learning how to navigate through ReShade is key to being able to utilize it effectively. Being able to navigate it with ease and configure specifically what you are looking for allows the user to create whatever their imagination allows for.

So, this guide will walk you through all the basics of what ReShade has to offer in it’s UI. Please do not skip this portion as it provides tons of valuable information that you could use to better your experience with ReShade!


Home Tab

The Home tab in ReShade houses several buttons and menus that you can interact with in order to change the way your game looks, as well as configure specific shaders.

As the Home tab is one of the most crucial tabs in ReShade for the end user, it can be a bit intricate, but everything that you will need to better utilize each function.

Below will be a dropdown that provides a disection of each part of the Home tab to help you become more familiar with it!


Preset Selection Bar

At the top of the ReShade Home menu will be preset selection section bar:

Current Preset

This bar allows the user to select, create, save manually, or configure their preset to auto save once changes are made.

By default, ReShade saves presets in the game directory, in a file called ReShadePreset.ini.


Shader List

The area below the preset selection bar is ReShade’s shader list: Technique List

This list will provide the user with all of the shaders that is installed for ReShade. If a shader is disabled, there will be a blank square to the left of the shader, and if it’s enabled, there will be a check to the left of the shader.


Edit Pre-processor Definitions Button

Below the shader list will be the Edit Global Preprocessor Definitions. This button allows you to control aspects of shaders and depth before they are loaded by ReShade:

Global Pre-processor Definitions


Shader Parameters List

The area below the shader list and edit pre-processor definitions button is the shader parameter list;

Effect Parameters

When you turn on a shader in ReShade, you will be able to see it’s exposed parameters to the user here. Any changes to these parameters happen in realtime. So, any changes you make show up right away, letting you see the effect of your changes instantly.


Add-ons Tab

The Add-ons Tab is for managing ReShade Add-ons:

Add-ons Tab

Each Add-on adds extra features or improvements to your ReShade shaders. They can offer new effects or tools for tweaking existing ones. Generic Depth comes with the ReShade Installer, but you can add many more.

Popular Add-ons include ShaderToggler - FransBouma, ReShade Effect Shader Toggler - 4lex4nder, and AutoHDR - MajorPainTheCactus.


Settings Tab

The Settings tab lets you tweak ReShade settings like shader directories, menu access keys, FPS meter configurations, theme settings:

Settings Tab

The dropdowns below detail commonly used options that you can adjust within the Settings tab:


General Menu
  1. Keybindings:

    • Here, you can set the keybindings for various actions in ReShade, allowing you to customize the controls:

      • Overlay key

      • Effect toggle key

      • Effect reload key

      • Performance mode toggle key

      • Previous preset key

      • Next preset key

  2. Input processing:

    • This setting lets users change the default behavior of ReShade’s input control:

      • Pass on all input - Allows your game to also receive inputs from your keyboard and mouse, regardless of where they are on the game window.

      • Block input when cursor is on overlay - Allows the game to receive inputs from your keyboard and mouse only when they are off of the ReShade UI.

      • Block all input when overlay is visible (default option) - Disallows the game to receive all inputs from your keyboard and mouse when the ReShade overlay is active.

  3. Start-up preset:

    • This argument allows ReShade to utilize a preset to use once your game has started. By default, ReShade loads the last used preset from the user. You can change this behavior by defining a preset file path.
  4. Effect... and Texture search paths:

    • These settings allow you to specify where ReShade should look for shader files. You can add multiple directories, and ReShade will search all of them when looking for shaders.

    • The default options are:

      • Effect search paths - .\ReShade-Shaders\Shaders\**

      • Texture search paths - .\ReShade-Shaders\Textures\**

  5. Load only enabled effects:

    • This option ensures that only the shaders enabled in your current ReShade preset are loaded. It can prevent issues with conflicting files/techniques from other shaders and reduce the compile time needed at the start of ReShade.

Screenshots Menu
  1. Screenshot key

  2. Screenshot path:

    • This option sets the location where ReShade saves screenshots. By default, it’s set to .\, meaning ReShade will save screenshots in the directory where the ReShade binary .dll file is located.
  3. Screenshot name:

    • This advanced option lets you specify the naming convention for screenshots. It uses macros to include real-time data in the screenshot name. The available macros are:

      • %AppName% - Current application name.

      • %PresetName% - Name of the applied preset at the moment of the screenshot.

      • %Date% - Current date (in ‘%s’ or seconds format).

        • %DateYear%, %DateMonth%, %DateDay% - Year, month, and day components of the current date.
      • %Time% - Current time (in ‘%s’ or seconds format).

        • %TimeHour%, %TimeMinute%, %TimeSecond%, %TimeMS% - Hour, minute, second, and millisecond components of the current time.
      • %Count% - Number of screenshots taken in the current session.

  4. Screenshot format:

    • This option lets you change the file extension and compression processing for your screenshots. The available formats are:

      • Bitmap (*.bmp) - Choose this for a lossless file that’s easy to edit but takes up more space. This format isn’t ideal for online sharing. If selected, you can enable Clear alpha channel to remove the image’s transparency layer if shaders support creating alpha channels.

      • Portable Network Graphics (*.png) - Choose this for a lossy file that’s almost identical to the original and good for online sharing. This is the default option in ReShade. If selected, you can enable Clear alpha channel.

      • JPEG (*.jpeg) - Choose this for a compressed file that saves on storage and bandwidth but isn’t as close to the original. If selected, you can adjust the compression quality.

  5. Save current preset file:

    • This option lets you save the preset used when the screenshot is taken.
  6. Save before and after images:

    • This option lets you take two screenshots of the same frame: one without ReShade and one with ReShade.

Overlay & Styling
  1. Show screenshot message:

    • This toggle enables or disables the screenshot notification message.
  2. Group effect files with tabs instead of a tree:

    • This toggle lets you choose between a tree structure or a grouped structure for shader configuration arguments. While a grouped structure can be more organized, the choice is purely preference-based. By default, this option is off, and the tree structure is used.

Statistics Tab

Statistics Tab

The Statistics Tab, shown in the image, is a great tool for tracking and improving ReShade’s performance. It gives detailed info on various aspects of ReShade’s operation. All of the data provided for it is invaluable to those developing shaders, and those attempting to help troubleshoot other’s issues.


Log Tab

The Log Tab is a key tool for monitoring ReShade’s operations and troubleshooting issues. It provides a detailed log of ReShade’s activities to help you identify where your issues are.

If something seems wrong, it’s recommended to share the error text or the entire log file, which is stored in the game directory as ReShade.log. However, logs are reset each time the game is restarted. So, remember to share or save logs before restarting your game!


About Tab

The About Tab, as shown in the image above, acknowledges and recognizes the work behind ReShade as well as the current version that you are running!


Depth Buffer

The depth buffer is a crucial part of any 3D game. It is a single channel image buffer which contains information about the distance of the scene to the camera, per pixel. Many ReShade effects depend on it and will not work correctly.

ReShade’s builtin Generic Depth Add-on scans the game data for the (likely) correct depth buffer and forwards it to the shaders.

In the following sections, you’ll learn how to verify the depth settings are correct and how to fix common issues.

Ensure you’ve correctly set up ReShade and followed the previous steps on the other pages! This guide assumes you’ve followed all instructions and have ReShade set up and running correctly.


Understanding Depth Buffer Basics

To start, enable the shader DisplayDepth. This shader is included with all ReShade installs through the ReShade Installer. If you do not have it, you can manually install it from Crosire’s ReShade-Shaders repository.

The image below shows what the output should look like. The depth buffer is on the right side, the normal buffer (generated from depth) on the left side.

Depth Buffer Reversed

If it looks like above, you’re good to go. Otherwise look below for the most common issues and solutions:


Reversed Depth Buffer

The image below shows that the DisplayDepth shader has loaded correctly, however, the depth is reversed.

Depth Buffer Reversed


You can solve this issue by inverting the RESHADE_DEPTH_INPUT_IS_REVERSED argument within the Global Preprocessor Definitions under the Home tab of ReShade. If it is set to 1, set it to 0 and vice versa.


Upside Down Depth Buffer

The image below shows that the DisplayDepth shader has loaded correctly, however, the depth output is upside down:

Depth Buffer Upside Down

You can solve this issue by simply inverting the RESHADE_DEPTH_INPUT_IS_UPSIDE_DOWN argument within the Global Preprocessor Definitions under the Home tab of ReShade. If it is set to 1, set it to 0 and vice versa.


Empty Depth Buffer

If your output resembles either of the images below, it lacks data from the Generic Depth Add-on:

Depth Buffer No Data Depth Buffer No Data - Reversed

  • Before proceeding any further, ensure that these anti-aliasing options are disable within your game:

    • MSAA ANTIALIASING

    • SSAA ANTIALIASING

FXAA or TXAA are acceptable, as they usually do not clear the depth-buffer information. Note that some games do not mention which AA method they use.

The image shown above is the output of DisplayDepth showing no data from Generic Depth. This means that:

  • Your game is not presenting a depth buffer

  • You have the wrong options configured for Generic Depth

  • You have the wrong arguments chosen for your global preprocessor definitions

  • Your depth buffer choice is wrong.


You can absolve this issue simply by toying around with Generic Depth in order to get the proper depth buffer active:

  • Try toggling on and off Copy depth buffer before clear operations and Copy depth buffer before fullscreen draw calls

  • Try selecting the depth buffer with the closest resolution to your game resolution

  • Try selecting the depth buffer with the highest amount of draw calls and verticies.

If at any point you start to see any features in the output that match the scene, re-check the preprocessor definitions.



Global Preprocessor Arguments

This section will provide you with the Global Preprocessor Definitions that can be utilized with the ReShade Depth Buffer.


RESHADE_DEPTH_INPUT_IS_REVERSED

This preprocessor is used when you can see the normals, but the depth image itself is not visible.

The argument can only be 1 or 0, so flipping the value for it should solve the problem.


RESHADE_DEPTH_INPUT_IS_UPSIDE_DOWN

This preprocessor is used when the image displayed by the DisplayDepth shader is upside down.

The argument can only be 1 or 0, so flipping the value for it should solve the problem.


RESHADE_DEPTH_INPUT_IS_LOGARITHMIC

This argument is used when the depth buffer displays numerous waves or “stripes”.

Very FEW games actually utilize this, so it’s rare that you’ll need to toggle or modify this setting.

The argument can only be 1 or 0, so flipping the value for it should solve the problem.


RESHADE_DEPTH_INPUT_X_SCALE | RESHADE_DEPTH_INPUT_Y_SCALE

These two preprocessors modify the depth buffer size along the X and Y axes.

They work in multiplcations and you can test them in the DisplayDepth shader before applying them to the Global Preprocessors.


RESHADE_DEPTH_LINEARIZATION_FAR_PLANE

This preprocessor will adjust the value of the depth range.

If the depth range is too narrow or wide, based on the visible black to white (close to far) gradient given from the depth in DisplayDepth, shaders that utilize the depth buffer will not be able to properly account for depth.

The values can be either extremely low or high, so you’ll need to experiment to determine the best fit for your specific case.
