On the quad core machines in-house (q6600 based) we're seeing between 30%-45% CPU usage for this patch; this was at 128 on all the machines we tried. For the level of complexity with the patch, we think this is acceptable CPU usage.
How are people measuring their CPU usage? Are they using their hosts CPU meter, or the OS's??
Motherboard: ASUS P5N32-E SLI
RAM: Corsair 800MHz Dual Channel
Further specs: see DAW below (No overclocking)
New empty project in Cubase 4.5.2, multiprocessing = On
Fireface 800 at 128 samples
Only Fusor in Cubase VST-rack, no notes played, 1x oversampling
Patch: SQBA Hop Grimes Bass
- Cubase ASIO meter: maximum! Overload LED = On
- Windows performance meter: 25-27%
To be complete... I do my mixes with 1024 samples buffer (= max for FF800)
- Cubase ASIO meter: almost maximum! Overload LED = Flashing.
- Windows performance meter: 23-26%
In both cases: Core A = max, B to D are idle (little activity)
It seems like Fusor calculations are all done by just one CPU-core on my system
Stand-alone, same settings, same patch:
- Windows performance meter: 17-19%
This time it looks like approx. 80-90% of the processing is done by one core and 10-20% by another.
