Yes, I update the 2D panels basically every time I update the graphics
on the screen....which I set my wakeupon conditions to be:
private WakeupOnElapsedFrames conditions = new
WakeupOnElapsedFrames(0,false);
Basically as fast as possible.
Ok, here is the test results on a DIFFERENT machine:
Dell 2.4 Pentium 4, 256 Mb ram, Nvidia Geforce2, Windows 2000
ISS model (955 KB) Test Model (2 KB)
(1) Normal Run 31 fps 35 fps
w/ animating sliders
(2) no animating sliders 38 fps 46 fps
(3) earth texture reduced
by 50 % ... anim. sliders 31 fps 34 fps
Mario
(4) reduced earth texture 39 fps 46 fps
no animating sliders
SO, it looks like the reduction in ISS model helps about 15%

Mario,
how oftem do you update that 2D panels?
If you update than each frame, this may slowdown you app a lot...
A 955KB model is a BIG model. A 5MB is a HUGE model.
Real-Time based applications reduces dramaticly the size of the models to
speed-up FPS.
But you can easily check if it is you problem.
Just try this small polygon wrl. If it improve your FPS, so you may have to
reduce your model a bit.
