Quark Shaders for ReShade
Quark is a repository of efficient and high quality shaders meant to adhere closely to physical methods while maintaining a consistent artistic vision, and ignoring the restricting limitations of DirectX9. If you do wish to use Quark Shaders in older Dx9 games, it's recommended to use a wrapper such as DXVK or dgVoodoo2.
