XFree86 Version 4.3.0 (Debian 4.3.0-0ds4 20030416150820 dstone@aedificator)
Release Date: 18 March 2003
X Protocol Version 11, Revision 0, Release 6.6


I did some more checks, and I should perhaps specify the problems a bit:
xmame using DGA normally works fine
xmame using xv normally works at about half of the normal DGA speed
xmame using DGA with a scaling effect works at about 1/13th of the normal DGA 
speed
xmame using xv with a scaling effect works at about 1/4th of the normal DGA 
speed
What troubles me is the 1/13th of the speed I get using a simple scaling 
effect under DGA. Neither fullscreen xv nor windowed running of xmame gives 
me such slow performance. Under the Morphix cd I have no such problems: it 
runs at about 1/2 the speed of normal DGA mode. Hence I figured it was either 
a driver or an XFree86 configuration issue.
