Ray Tracing Simulation Shader

SSR + HBAO + SSGI

This shader needs access to the depth-buffer.

Usage: Extract to /reshade-shaders folder

Note: Heavy loads, use low AO sampling. Load escalates exponentially with game resolution.

Note 2: On the first run compilation can take up to 2 minutes. Be patient. /// THIS WAS FIXED ///
