This is a preset for def_hud that centers most of the ui elements except the ap and hp bars, which are in the bottom corners. as it is a preset you need to download the def_hud mod first to use this. it is made for screen resolutions of 2560x1080 and i am not sure if it will work on standard aspect ratios however i will make a 1920x1080 version if someone says it looks weird on standard screens. if you prefer to install manually the file must go into the DEF_CONF folder of def_ui.
