Applications may want to operate at 64bpp, but Render is limited (currently) to 32bpp by the X protocol and is further limited by attempting to expose only that which can reasonably be expected to be accelerated in the display hardware. As this definition changes, so will Render, but for now, PC frame buffers don't do 64bpp. > DX9 is apparently pushing for hardware-accellerated gamma correction > operators in the shaders, for texture lookups, all over the place. At > least, I'm hopeful. :) This is a significant part of the interest in providing gamma corrected compositing for Render -- the hardware will support it in many cases, so we need a software interface through Render to take advantage of it.
