After providing general tips for getting a bit more out of Dark Souls II visually, renowned modder Durante has written another article for PC Gamer detailing his next major release. The DSfix creator has a new tool, GeDoSaTo, for stuff like texture modding and downsampling. Better yet, it's intended to eventually go beyond Dark Souls II and "work with any 3D game."
Through library interception, the tool "allows for game downsampling without any hardware limitations, and texture modification in any game which uses the default texture loading mechanisms provided by DirectX." The image above is evidence of why this is a great thing.
Download GeDoSaTo over here, but know it's a work in progress. This guy.
