Description of my visual design:
- Performer is run in APPCULL_DRAW
- APPCULL runs with a non-degrading prio at its own isolated CPU
- DRAW runs with a non-degrading prio at its own isolated CPU
- Graphics are drawn into a GLX window, using 8-bit multisampling
(pfuGLXWinopen is used to open the window)
Description of the problem:
Running the application on a 8 CPU Onyx (IRIX 5.3, Performer 1.2)
with RE2, 4RM, everything seems fine: 60 Hz most of the time. UNTIL
you start to touch the system. Scrolling an X-Window on the system
will essentially STOP the Performer application... Avarage frame rate
drops below 10 Hz, even down to 1 Hz. Sometimes (when heavily
scrolling an X-window e.g.) I see the visual process wait for half a
second or more.
Question:
Is there anyone who has an idear where to look for the source of my
performance troubles? What are the Performer processes waiting for???
Statistics problems too...
Getting up a statistics graph would help me. Unfortunately, I can't
get the stats display up too. Initially, I used a GL window to draw.
The stats worked OK then. Eversince I work with a GLX window,
statistics display is a crashing action.
Looking forward for responses that make me happy again...
