This tool allows you to change Level Of Detail for ATi/AMD cards on the fly (in-between GT loading screens i.e). It will support NVIDIA cards when they fix their nvapi (never).
Notes:
- To close the hotkeys monitor, press Ctrl+Alt+0 on your keyboard.
- The hotkeys monitor is written in AutoHotkey and will trigger false-positives with some antivirus software. Get the source code and compile it yourself if in doubt.
