以下为《巫师3》关于画面特效修改教程，所以大家在修改之前记得一定要备份，当然在这些文档中还发现了DLC相关的内容，不过实测目前是无效的，以下为详细的资料。
【在游戏的存档目录和游戏本体目录里发现了DLC设定文档和画面特效修改文档，实测部分修改有效，研究透了可实现2013年E3的画质】：
有三个文件值得修改。注意备份！！！
第一个是dlc.ini，地址：The Witcher 3\bin\config\base\dlc.ini，内容：

第一个文件改DLC实测无效，估计波兰人还没实装DLC补丁，第三个文件修改带有GRASS和TREE的选项为0时，实测进游戏青草全部消失，树叶渲染距离近了，如果全高特效时帧数低的人可以试试。截图就不上了，光秃秃的很丑。
三代支持直接截图，只要按键盘上的截图键【PrtScr】，就能直出截图至：The Witcher 3\bin\x64文件夹下，图片是PNG格式的。
