Result seem to vary - when I disable Vsync I get lower framerate than when I
leave it at application controlled. Like from 3.9 fps to 4.5 fps. I missed
Lucs post - was it here on the list?

You guys should really try "Disable Vertical Sync" in your graphicsdriver
options,
sitting infront of an 1920x1200 TFT at work with that set I see an
increase in
redraw by, hmm, factor 5-7, like from ~6fps to ~42fps in XSI 5.11/xp32.
Thanks alot to Luc-Eric for pointing to that.
Cheers
tim

Since we were under a deadline... we haven't had the time to fully test
all the great theories as to why my 5 year old laptop was able to
completely blow away several boxx machines (and even some other laptops
in my area) at simple things like particle playback.. and that sphere
moving across the screen test.. which was pretty simple
however, i discovered one thing the other day..
i asked my friend to try the simple tests i described above; a simple
create particle from sphere playback (all default settings - at both
real-time playback.. and all frames).. and the sphere moving across the
screen playback also..
what i noticed was that his was pretty slow also..
then i tried to open my XSI to show him my playback..
but to do it.. i had to do one thing since XSI wont launch on my laptop
normally...i had to UNINSTALL quicktime to run XSI..
its something i have been doing ever since that problem cropped up in
4.2 with quicktime installed (even quicktime alternative) XSI will not
fully launch... obvisouly some kind of opengl. driver conflict
thing...it crashes.. but since its on my laptop.. ther eis no fix (can't
replace the gfx card) .. so i deal with it..
anyway..
i realized that that was the one MAIN software/hardware difference
between my laptop beating all those other machines of varying hardware
and age configurations.. yes the cards were all different.. but the
others should be BETTER.. not worse
SO... it made me wonder if other people wanted to test the theory (as i
will do so when i get back into the office next week).. if you uninstall
quicktime.. and run XSI... is there a performance increase..
i'll post my results when i can
if anyone would like to add to this.. please do..
Anyone running 64bit windows, or linux will not have QuickTime installed.
