Another idea for utilizing precomputation: for each 'cell' in your
precomputation structure, render a bunch of sample viewpoints at full
resolution, all the shaders, fog, DOF, post processing etc. turned on,
 with *all* MIPs loaded, then remove one MIP level at a time for each
texture and measure the amount of additional error doing so caused in the
sample frames. Now you have a per-cell ordered list of (texture,mip) pairs
ordered in terms of importance for overall scene error. Ideally use some
perceptual metric for your error function.
