Resolume Forum

I was trying to experiment yesterday with a live cam.

Apart from huge drop in performance (about 50% in fps) there were two issues:

- MIDI controller much less responsive, video capture friezes

- frequent crashes / freezes - bot

I use acer 5024 WLMi - Turion M-34 - 2 Ghz 1.25 GB RAM

MIDI - Alesis Photon X25 with audio input - USB 2.0

generic USB 2081 tv-box device (called batman II =] ) - USB2.0

this situation renders MIDI + audio + vid capture unusable

And I like

is it because of the data overload on USB? I use different ports, but they do connect to one chip in the end?

Would using firewire capture help? (they say it takes a lot of processing power away)

is it the case of single core processor, overtaken by resolume, so no processing power left for video capture and MIDI? When I used MIDI OX before, it did tend to create big delay too.

would the dual core help in this situation? Ill test it on my x2 - MIDI OX works much better on this other machine.

Have done the testing on dual core X2 (2.2 Ghz, 2GB)

everything works fine
no delay on MIDI, nor Video in, no freeze in BPM, no crashes

all nice and smooth

this leads me to conclusion:

dual core IS important in resolume

especially when you do video capture or run other software in background (like midiox)

difference in speed is minimal (2 Ghz vs 2.2) so the claim 'the more ghz the better' seems a bit out of date too

"the more ghz the better" has been out of date for a few years.

Dual core is not important to Resolume itself, as it doesnt make use of it. its only important if your trying to run more than just Resolume at the same time on a single machine, as Resolume tends to be processor greedy to ensure maximum performance for the software.

firewire does definately give better results for video streaming, especially if you already have something using the USB buss. I certainly wouldnt expect it to work well when streaming audio, video and midi over the same buss.

yes, but that's still as 'ideal computer for resolume' is officially described.

which does not seem to be the case anymore

USB is not a bottleneck as it works way better on dual core machine (x2 3800)

Firewire is faster than USB and requires less overheads, so using multiple devices on USB will create a greater bottleneck effect.

I've tried that last Friday.
Unfortunatelly, firewire live feed performs even worse than USB with inconsistent frame rate of 1-2fps.

I'm using acer 5024 WLMi
Turion ML-34, 1.25GB RAM,
7200 internal HDD, XP SP2,
similar problems occur on clean system.
