#extension GL_EXT_gpu_shader4 : enable
#define TAA //if disabled you should increase most samples counts as I rely on TAA to filter noise
//#define FAST_TAA //disables bicubic resampling and closest velocity, improves fps especially at high resolutions
//TAA OPTIONS
//#define NO_CLIP //Removes all anti-ghosting techniques used and creates a sharp image (good for still screenshots)

#define ANTI_GHOSTING 1.0 //[0.0 0.25 0.5 0.75 1.0] High values reduce ghosting but may create flickering
#define FLICKER_REDUCTION 0.75 //[0.0 0.25 0.5 0.75 1.0] High values reduce flickering but may reduce sharpness
