ReShade is a popular addon for many games which allows the application of multiple postprocessing shaders such as bloom, fake HDR, SSAO, sharpening and depth of field. GShade is a custom-built ReShade program for FFXIV which prevents clashes with the UI, while also coming with an easy installer and almost all the required shaders. Most presets out there are full of fancy shaders such as MXAO and depth of field that make them near unusable in regular day-to-day gameplay. This preset is different; I use it during all gameplay, and I have still included the ambient occlusion but got rid of most of the bugs which allow it to be used even in close up cutscenes.

All images above, even though some are using Gpose, are totally raw without any Gpose effects, thus what you see above is representative of what you will get with this package.
