I think this is my last question about that subject ... Using video texture
map at 25HZ in Performer everything working fine ! ... When I try to make
it run to 50HZ without video texture everything is still fine with a very
tiny drawing time (about 4 msec) ... but at the time I try to make it run
at 50HZ with the video texture it refused to maintain more than 25HZ with
quite the same tiny drawing time ! ... Something seems to keep the speed
to 25HZ ... Has the video link an influence on Performer timings ? ... or
is the subtexload putting the process in some waiting state to make the
video frame be grabbed ? ... Test are done on Onyx/RealityII/Sirius ...
with APP-CULL-DRAW in the same process cause APP takes less than 1 msec to
execute and CULL less than 1 msec too ! ... Any ideas are welcomed ...
