Replacements
Listings that take over the same core job as Special K.
ReShade
Generic post-processing injector adding shaders and effects to almost any game.

Lossless Scaling

Lossless Scaling is a paid Windows tool for frame generation and upscaling in windowed or borderless games, narrower than Special K's frame pacing and HDR toolkit.
