The Witcher 2: Assassins Of Kings – High Texture Pack

Even though The Witcher 2 has some of the best textures we’ve seen so far, modder TC1984 went ahead and enhanced them by using Gibbed RED Tools, QuickBMS and Photoshop. The end result is even more crisper textures that can really be appreciated when you are pretty close to them. This texture pack is currently at its 1.2 version which among other things, replaces some grass & moss texture files with matched colors.
This texture pack can be downloaded from here.
Here are some instructions in how to install/uninstall it:
Extract files to your game directory you’ll get “The Witcher 2\CookedPC\environment_levels” and “The Witcher 2\CookedPC\items\weapons” (your environment_levels folder must be in the same folder as your pack0.dzip)

Remove your environment_levels folder from The Witcher 2\CookedPC
Re-build your pack0.dzip after patch1.3 installed , the game will not start. extracting everything to your Witcher 2\CookedPC folder that works. (also with patch1.3)
