tried to use perfly as a simple quick check on running 4 separate
copies to see if this would work - set up command line stuff so that
APPCULLDRAW was forced and tried it with and without all the
lock down and ndpri stuff - four copies barely ran (yes, the
database is small, the app simple, and I don't think there was
cockpit error) - two copies ran a bit better than 4 (10 to 20 Hz
with violent oscillations between rates), and one copy ran very
well at a solid 30 Hz - the stress line looked like a schizophrenic's
EEG with anything greater then one perfly running - three powerflips
did not effect the one perfly, but two perflys trashed each other
does perfly "do something" that precludes having multiple copies running -
for example, I can run 4 powerflips and each runs fairly smoothly - but
when I run two perfly's, unfair heavy-weight wrestling choke holds
materialize
ok, what is the suggested best way to do four database views with
each view being unique and hidden from the others? the geometry
is fairly simple and the frame rate needs to be 8 Hz or better
(like, say 10 or something attainable!)
one approach seems to be to have the four databases loaded with one
performer app and switch between one of the four scene graphs with
each frame, rendering the database at 40 Hz while effectively
rendering each user's view at 10 Hz (there is no need for synchronization)
another approach seems to be the four copies of performer as
mentioned above
which? or what?
thanks!
bye.
