This mod is a subtle Reshade preset. It is designed to enhance the look of the game and adjust the colors slightly. If you're not familiar with Reshade, it is a tool for developers to create presets for games. These are designed to be performance-friendly, so you don't have to worry about this affecting the performance of your game.

The only thing you need to do is download and install this file to where you have Dragon Age Origins.exe installed (where Reshade will install.) Then, run the program and select Dragon Age Origins.exe from where you have installed it. You will need to choose "Direct3D 9" when the program asks for rendering API.

Then, select all shaders to download when it prompts you to.

Once Reshade has finished, click on "Edit Reshade Settings." Select the preset from the drop-down menu. If you are not interested in editing, tick Performance Mode and Skip Tutorial. That's it!
