Ha! No, I meant that a 2x improvement between bad texture format and an

sounds about right when I was looking on my machine trying to enable
f16c on older compiler
Right, right, it's all about the benefit.
In my case, I was thinking mainly of the texture system, and so far we have
used TIFF for the majority of textures, with usually just a few exr maps in a
frame (environment lighting, mainly). If we were to switch to exr as the
primary texture format, th
