I didn't know that "The Matrix" was developed by Matrox.

Yes,

the idiotproof test is the following:
install 2.2.10 + lowlatency patch  ( not SMP !), 
tune the IDE diskas as described in the README
and run a testsession
if the GFX stress graph is the only bad graph,
then I'm sorry but you have to throw away your videocard if you want
to do reliable low latency stuff.
