Summary	0005924: Renderer to operate on single-precision floats
Description	There's a significant performance gain in rendering GL_FLOATs instead of GL_DOUBLE, let alone the 50% memory saving in the frame buffers. With floats, rendering my benchmark scene 100 times took less than 3s, compared to 7.5s with doubles.
Tags	No tags attached.
