I don't believe it gets rid of the overlay planes on Impact machines.
It just changes the default visual to TrueColor rathern than
PseudoColor.  The downside is that mapped windows take up more memory,
but that's about it.  Pixel accesses happen on a halfwork boundary
(well, word on an O2) and, thus, blits are -much- faster.

I can't imagine that Maya would be adversely affected, since it can
still -ask- for an overlay plane.  For example, Jot does.

It's a night and day difference on an both an Octane/SI and I2/SI.  For
playing around in the GUI, an I2/SI with this configuration file is
snappier than an Octane without it, given equal CPU clocks and memory.
