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.
To manually download your new content on the PC: Download the installer from the link below and run it. Run Dragon Age II. Open the Options menu. Select Video options. Check the "Hi-resolution textures" checkbox. Note: In order to enable the "Very High" setting you will need a video card that supports DX11 and the latest drivers.
