I am running a fairly simple 60 Hz performer application on a single
processor of my 4-CPU Onyx (by using PFMP_APPCULLDRAW). When I
display statistics, I notice that APP and CULL occur immediately at the
beginning of the frame taking about 0.1 milliseconds each. Then nothing
seems to happen for about 7 milliseconds until DRAW (which takes about
5-6 milliseconds) starts. DRAW always ends 3.3 milliseconds before the
end of the frame. If DRAW takes longer, it seems to start sooner in the
next frame. If it takes less time, it starts later next frame. I need more time
at the end of each frame to do some additional processing on this CPU.
Why is there this long delay before the DRAW? Is there any way to
DRAW sooner?
Thanks in advance,
Jim Barhorst
