audio fft analyse performance...

hey folks,

the audio fft analyse loose performance when more then one active layer are triggerd, it slows down, and the precision trigger moment of audio fft are gone.

havenÂ´t seen that effect in resolume 2.3

3,2 ghz, 1gig ram 400mhz, extern sata2 hdd, gf 6600gt 128mb, win xp sp2, pic mjpeg 400*300

any idea...

i was gonna ask the same thing, i have a diferent machine 2.4ghz 2gbRAM gforceti4200-128mb and the pic video codec...

and cygnus-x is right it slows to more than half of the fps, and he's right saying that 2.3 didnt had that...

looks like i'm not presenting nothing new, just backing an opinion...
anyway thanks for your time reading this and let us know of any news..

i got something new to add,
if i have fft analisys on and play a clip on bpm-mode, resolume crashes and returns to windows.
so apparently bpm and fft aren't working together.

Are you using onboard or external soundcards?

...i thought about that, but resolume 2.41 crashes at my last try after ten
minutes, so i thought thatÂ´s fft analyse is not longer my first problem.
...but itÂ´s an intern soundcard and it never gives me trouble in 2.3 version???

Hmmm. Dunno. Maybe only Bart/Edwin can answer you that.

Why you not try to update your soundcard driver? Maybe this can help.

after format c:, a new clean installation with only resolume 2.41...

it runÂ´s very tight and stable

i test it for round about 1hour with full effect performance, beatcount, fft analyse, and uc-33 midi triggering

i thougt the keypoint was 1. clean system 2. i reduce the process resolution to 400*300 like the output resolution.

if i increase the process resolution to 800*600 the performance break down.

i hope thatÂ´s it

oh... that problem was discribed in manual...sorry

but i wanÂ´t to go further

with 400x300 resolution the system runs very tight

but my question is, if i like to increase resolution to 640x480(footage rendered), which parameters will be responsible for a tight performance?

does resolume support dualcore? raid0 or raptor hdd?
