The game Mass Effect 3 does not have options in the main menu that will allow you to change the graphical settings. This mod will help you with that problem. With ME3 Graphics Tweaks, you can easily apply changes to the graphics of the game. 

The settings can be changed in a very simple way. You can customize configurations. World textures, shadows, and characters will also look sharp, less glowing, more detailed, and brighter. This mod will also bring increased shadow resolution, saturation, and filtering. The performance will also be optimized, so it will not cause game crashes or any other issues.
