jitter multi screen slow down!

April 21, 2006 | 11:25 am

hi there,

I know this may not be a totally new question but I didn’t find any answer when looking in the
archives of the list, so let me ask again.
I’m working on an installation where I adjust two beamers pointed on the ground to make one image.
I send the message "rect 0 0 1280 2048, border 0, floating 1" to have the jit.window covering my
two screens.
then the frame rate drops to 15 with only 3 sketches and 3 320*240 textures while in a small
window it reaches 50 and in fullscreen mode on one screen it’s about 35.
I work on a G5 Dual 2.3 gh with an ATI radeon 9600.
I once heard that Nvidia cards were better for this two screen stuff as they consider the two as
one which is devided for displaying.
is this right?
anybody ever tried this out?
I don’t want to go and buy another graphic card if i m not sure…

I also would like to know how to get rid of the menubar and the dock as the "fsmenubar 0" message
only works in real fullscreen mode.

that’s it, I hope I was clear enough.
any help is welcome.

Hello

I you stretch a single jit.window over 2 screens, it will probably disable
the openGL hardware acceleration. (-> software rendering=slooowwww)
You have to render your scene in 2 different windows, one for each screen.

I will try that out!
thank you.
and thanks also for ‘hidemenubar’ to send to max even if I don’t need it if mathieu’s tric solves
my problem.
by the way, could anybody remind me where all the ‘;max …’ messages are documented? (if they are
somewere)
I m also interested in a way to monitor the GPU activity to check this hardware software rendering
stuff.

Topics and Tutorials. Where else? Look at the TOC. Hint: Last chapter.
