This will add the option to enable higher detail replacements for most textures in game. A big difference will be noticed on level art especially. Requirements: To get the most out of the high resolution texture pack, we recommend running the game with the DirectX 11 renderer (requires a DirectX 10 GPU and Windows Vista SP2 or Windows 7). We also recommend a video card with at least 1 GB of video memory. Most of the benefits from the Hi-resolution textures will only be seen if you are able to run the game in DirectX 11.
