While NVIDIA's RTX and AMD's FSR dominate headlines, screen-space shaders like xukmi.shaders.fx are not obsolete. In fact, they are complementary. Because xukmi.shaders.fx works entirely in screen space (post-processing), it does not conflict with DLSS or FSR's upscaling passes.
The source code and specific .shader files (like SkinPlusTessReflect or MainOpaquePlus ) are hosted on xukmi's GitHub . xukmi.shaders.fx
