I think you misunderstand. I do not want to control the frame rate I
just want to know how fast opendx can render one of our larger datasets.
(I probably wasn't clear enough in my request for help)
With the caches turned on things are faster but it still takes time to
draw and render all of those polygons :-) and how long it takes to
render a frame is the quantitative information I need.
Frames-per-second is very meaningful for me as I am comparing the
performance of several different video cards. As there is no better
benchmark than running the actual programs and data one uses, I wish to
test opendx performance on various video cards.
FPS is often used as a metric to determine the performance of video
hardware. Many vis packages have a way to display the framerate (vtk,
performer, inventor, vmd, etc.)
What would be nice is if there was in opendx an option to the image tool
to display fps so while I am rotating a large data set I can get the
framerate. The throttle option would be of no use as I want opendx to
render as fast as possible.

No offense, but that is meaningless; that is, it is not like Quicktime
or NTSC or anything else that has a 'frame rate'.
The playback from cache is entirely machine (CPU, graphics card, etc.)
dependent. You can change the apparent rate with the 'throttle' setting
(I think it's in Image: Options, but haven't used it for 10 years). Even
then, it's just an approximation of frames/second or seconds/frame.
To get at what I presume you really want (control), output a series of
still frames (tifs for example), then combine them in an editing program
like Quicktime Pro, Final Cut Pro, etc. or even Cleaner: that is a
program that understands a time base. In all those programs you have
varying amounts of control over the output frame rate desired.

Any suggestions on how to get the framerate of an opendx visualization?
