Dear Vivian,
Your figures sound about right as I also get very
frustrated with this also, in fact when I am filming making the movies I have
found something interesting!
When I use mibs for example and set it on a fixed heading to do straight in
line pan scans for panoramic shots such as moving in a straight line from point
A to point B the first time it stutters like hell, then I use the reverse
button (Brake) and pan back out (Reversing along the same path) and do this
several times forward and back then for some odd reason maybe due to caching it
becomes smooth and no stutter, this is a technique I now use all the time when
I am making the OLeg Movies, but unlike you I can't afford to Buy expensive new
graphics cards so YES I agree the frame rates do need more work, and based on
the method I tried in the point A - B scenario maybe something in the caching
needs looking at, maybe even some sort of dynamic pre-processing of scenery
just ahead might solve these issues or using a dynamic quality resolution
technique to reduce the scenery quality being displayed based on cpu usage
might help?
Regards, Aerotro
PS,
I am planning and currently working on part 4 of OLeg's Adventures some
scenarios require video using AJ's Duplo car and I want to simulate a speeding
car with smoke from the tires / exhaust and so I will most likely be adding
special effects for this, unless someone wants to make the job easier by
implementing a smoking exhaust to the car? Every bit of help counts :oD

Hi
About 10 days ago I got fed up with low frame rates using OSG around KSFO,
so I went out and bought the best nVidia AGP card that I could find - 7600gs
with 512Mb of VRAM. I fitted it with great anticipation to my machine - P4
2.8Ghz/800Mhz FSB with 1.5 Gb of RAM running XP - and, precisely NOTHING. No
change in frame rate between the new card and the old - a FX6200 with 256Mb
VRAM - for FG-OSG-HEAD. On the other hand plib-HEAD flies. Here are some
comparative results:
