Dragon Age II launched today in North America and BioWire has decided to surprise PC gamers with a download of a high-resolution texture patch which adds an option to enable higher detail replacements for most textures in the game.
Obviously a beefy PC would be required, but it's nice to have the PC version having something over the console releases. To take advantage of the high-resolution textures, you'll need to have a video card with at least 1GB of memory. BioWire has also noted that most of the benefits from the high-res textures will only be seen when running the game in DirectX 11 mode.
This requirement more or less limits the patch to owners of AMD Radeon HD 5000 and 6000-series or NVIDIA GeForce GTX400/500-series. The patch can be downloaded from here and is 1.1GB in size, you'll need to follow the below instructions to get it working:
Download the installer from the link above and run it.
Run Dragon Age II.
Open the Options menu.
Select Video options.
Check the "Hi-resolution textures" checkbox.
