High-res reflections, Realistic lighting, Color Correction [Shader Patch Preset] addon

Rather than uploading a million before/after screenshots, I recommend reading about SleepKiller's improved SWBF2 shaders here. My preset is nothing crazy and should run well, but you might want to disable anti-aliasing if your computer is a potato. To do so, just open 'shader patch.yml' in any text editor and replace 'CMAA2' with 'none'.
