Accumulation Buffer -4 GL_RETURN takes values from the accumulation buffer, multiplies them by value, and places the result in the color buffer(s) enabled for writing. GL_ADD and GL_MULT simply add or multiply the value of each pixel in the accumulation buffer by value and then return it to the accumulation buffer. For GL_MULT, value is clamped to be in the range [-1.0,1.0]. For GL_ADD, no clamping occurs. glClearAccum( c ); glClear( GL_ACCUM_BUFFER_BIT );.......

TITLE : performance - Eliminating redundant (?) openGL calls - Stack Overflow
* My code does a "clean initialize" by calling glClearAccum(0 , 0 , 0 , 0); and glClearColor(0.0, 0.0, 0.0, 0.0);. These are understandably redundant, but can I rely on that in all circumstances? If some openGL implementation doesn't guarantee this initial state, it's safer to make the calls even though they're redundant in most cases........

TITLE : performance - Eliminating redundant (?) openGL calls - Stack Overflow
glClearAccum(0 , 0 , 0 , 0); and glClearColor(0.0, 0.0, 0.0, 0.0); are redundant when you draw the whole screen every frame (which you probably do), and they are quite heavy. There is no point clearing the framebuffer, just draw over the last frame........
