TITLE : opengl - GLSL 4.2 Image load and store & memoryBarrier - Stack Overflow
the value for 'uv' can be the same for multiple rasterized pixels. In order to get the proper result, of course I want no other shaderexecution to write into my pixel inbetween the calls of imageLoad() and imageStore();.......

TITLE : imageLoad/imageStore VERY slow
My fragment shaders render the sponza scene smoothly when implementing e.g. screen space reflections that take the screen buffer data from a buffer texture of a previous, 'normal' scene render pass, but as soon as I involve one to two imageLoad() calls per pixel to get data from per-pixel-linked lists instead of buffer textures, rendering one frame takes between 1.5 to 3 seconds........

TITLE : imageLoad/imageStore VERY slow
Yes, it strongly seems as if imageLoad() is the call that does extremely slow down e.g. my Screen Space Reflections fragment shader........
