Since [http://forums.pcsx2.net/Thread-Custom-Shaders-for-GSdx?pid=343285#pid343285 January 2014], GSdx supports the use of an external file (shader.fx) to be used as an external shader, '''separating it''' from the [http://en.wikipedia.org/wiki/Fast_approximate_anti-aliasing FXAA] shader. This feature is only available for Windows users with graphics cards supporting Dx10 or higher, but people with Dx9 only card can still use the internal [http://en.wikipedia.org/wiki/Fast_approximate_anti-aliasing FXAA] method.
Since [http://forums.pcsx2.net/Thread-Custom-Shaders-for-GSdx?pid=343285#pid343285 January 2014], GSdx supports the use of an external file (''shader.fx'') as additionally loaded shader program, ''alongside'' with the [http://en.wikipedia.org/wiki/Fast_approximate_anti-aliasing FXAA] shader. This feature is only available for Windows users with graphics cards supporting Dx10 or higher.

'''1)''' Download your shader of choice (see list of shaders bellow).
# Download your shader of choice (see list of shaders bellow).
# Extract the ''*.fx'' file inside your ''PCSX2'' directory '''(where the main executable file is located)'''. Note that from PCSX2 version ''1.3.0'' the shader should be placed in a special ''shaders'' folder instead of the root folder.
# Rename the extracted file to ''shader.fx'' (remember to back up the existing ''shader.fx'' file in case you will want to restored it later).
# Enable the external shader in GSdx using one of the three methods below:
## Enable the Use FX Shader checkbox in the GSdx settings.
## Press ''Home'' while in game.
## Add '''shaderfx=1''' line to ''GSdx.ini''.


'''2)''' Extract the ''*.fx'' file inside your ''PCSX2'' directory, '''where the main executables are placed'''.
{{Tip| On ''low end'' systems the combined use of '''Fx Shader''' and '''FXAA''' and/or a high custom resolution can hinder rendering speed.
 
Try to fiddle with settings until you find the one that better suits your need for a particular game.}}
'''3)''' Rename it ''to shader.fx'' (remember to back up the existing ''shader.fx'' file to be restored if needed).

*On the GSdx settings, enable the Use FX Shader checkbox.
*In game, pressing the ''Home'' key.
*Set ''shaderfx=1'' on ''GSdx.ini''.


{{Tip| On ''low end'' systems, the combined use of '''Fx Shader''' and '''FXAA''' or a high custom resolution can cause a performance loss.

*You can find a number of shader.fx files created by the community in [http://forums.pcsx2.net/Thread-Custom-Shaders-for-GSdx this] forum post.
*KrossX [http://www.mediafire.com/krossx shaders] can be downloaded here.


On future versions '''(and current development builds)''' the external shader is installed on a ''shaders'' folder. Also, the PCSX2Fx Shader is included by default.

*You can find a list of shader.fx files created by the community on [http://forums.pcsx2.net/Thread-Custom-Shaders-for-GSdx this] forum post.
This is a collection of shaders included in ''GSdx.fx'' file. It's also associated with a configuration file ''GSdx_FX_Settings.ini'' that can be modified by the user. The collection is supplied by default with PCSX2 starting with version ''1.3.0'' (see the most recent [http://pcsx2.net/download/development/git.html development builds]).

This is a suite of shaders included on a single ''shader.fx'' file. It's also associated with a configuration file that can be modified by the user. It's included by default on the most recent builds.
<br /> The files ''shader.fx'' (the shader itself) and ''GSdx_FX_Settings.ini'' (the shader configuration file) have to be placed on the PCSX2 directory, where the main executables are.

'''Asmodean''': "You can enable, or disable each effect, from inside the shader settings file. Everything is customizable. Settings are clearly sectioned, and labeled. Use the documentation comments inside the configuration file for instructions on each option. The default setup is enhancement settings (compliment/enhance the original game's image, without changing it's overall tone & feel) and pretty neutral, so people who don't want to play with the settings can just turn it on and use it."
{{Tip|To get the most out of GSdx FX, try experiment by customizing settings and combining some effects together.}}

Use the documentation comments inside the configuration file for instructions on each option. The default setup is enhancement settings (compliment/enhance the original game's image, without changing it's overall tone & feel) I keep the defaults pretty neutral, so people who don't want to play with the settings can just turn it on and use it.

=SweetFX=
GDdx (in Direct3D 11 mode) is compatible with [http://www.guru3d.com/files-details/sweetfx-shader-suite-download.html SweetFX] post-processing effects suite.<br />
Use [http://sweetfx.thelazy.net/ SweetFX Configurator] to install and configure it. Simply add PCSX2 to its GUI and click on ''Add SweetFX'', the configurator is going to copy the required files automatically, you can remove them by clicking on the ''Remove SweetFX'' option at any time.
 
 
'''SweetFX''' Ingame hotkeys:
* ''PrtScrn'': Take a screenshot.
* ''Scroll Lock'': Toggle SweetFX '''ON''' and '''OFF'''.
* ''Pause'': Reload the SweetFX settings file (useful to change the the effects on the configurator and see the results while in game).
