This is hardly a valid criticism of GGI/KGI as a whole! XGGI is
merely a GGI-using application that currently used a dumb framebuffer and
hasn't been recoded to use copybox() and friends. This is supposed to
happen sometime soon, and when it does XGGI will be accelerated if the
underlying KGI driver being used is accelerated.

GGI Descent now runs as fast in 640x480 as DOS Descent did in
320x200. This is with NO acceleration. You were saying?
