Is Capture One LE CPU utilization limited?

Dajuan
First, this is my first post in this forum. This software is absolutely the best I've come across.

I've noticed that after batching jobs of hundreds of images (current job: ~300 images, 117 minutes), my CPU utilization stays ~50%. I shoot w/ both Fuji S5 and Nikon D200. My system comprises of:
- Intel E6700 dual core processor
- 4 GB DDR2-800
- 7200 (storage) & 10,000 (OS) RPM SATA drives
- WinXP SP2

In such a config, and with only 50% CPU utilization on batch processing, what limits such a system from completing the job even faster?

Would any benefit be realized if a quad core CPU was used, or would that result in 25% CPU utilization?

I checked, but the LE version of C1 (3.7.7) doesn't seem to have the check box for limiting processing to a singe core (both of mine are active via Task Manager).

    Hello
    I think only C1 Pro supports more than one CPU.

    You have two in a dual core.

    Is this documented anywhere? I'm planning to upgrade from a dual core to a quad core processor strictly for improved rendering (video & still).

    Hello

    Capture One 3.x on Windows support up to 2 CPU cores.
    On Mac it supports 8. I can not currently tell you what the future will bring but you are in for a pleasant surprise.

    So C1 3.x supports dual core processing via both C1 Pro and/or LE version - that's good news. But why would CPU utilization apparently limited to ~ 50%? Is there a way use more (increase the utilization) and decrease the rendering time?

    Is the 2 CPU cores limited to Pro? I, too have tried LE 3.7.7 with dual core and never had more than 50% CPU utilization. If upgrading to Pro will let me use 2x as much CPU, I will do it.

    Great teaser for 4.0. I'm ready to beta test for you!

    Thanks,

    Is the multi-processor support cpu dependant?

    I have a dual 64-bit AMD that seems to use all of the processor(s), but my Core2Duo does not!

    Paul, let me get this right.

    On your AMD dual core machine, you get 100% CPU utilization on both cores when converting from raw to JPEG.

    But, on your Intel dual core machine, you only use 50% CPU utilization on both cores when converting from raw to JPEG?

    If both machines were doing the exact same job, does one complete the task faster than the other? If so, which one?

    Yes.

    Yes.

    Yes. The AMD is faster (which pisses me off, since Friday I ordered a Core2Quad for just this purpose).

    although I have not looked at CPU utilisation percentages, it seems my C1 LE (3.7.6) does make use of both cores in my Core2duo laptop. A certain job with 300 raw files is about 20 minutes faster than on my desktop (Athlon 64 3400+ single core 2.4GHz). Since the cores of my laptop run at 1.6GHz I guess both must be used in order to outperform my desktop.

    Might you be able to run a few images through your set up and share your CPU utilization on your Core 2 Duo laptop?

    C1 moderator has already confirmed C1 will use 2 cores, but utilization percentage is the outstanding item. I see only 50% usage on both cores, same as Paul above.

    Would be nice if one of the P1 guys would chime in regarding CPU utilization. Please?

    My Core2Quad processor runs at 25% utilization when processing Fuji S5 files, although they do process faster (37 seconds) than Core2Duo or Dual Xeon processors (66 seconds).

    I will try to do more testing with different machines and file types to see what I come up with.

    On my HP compaq 9420 with core duo the cpu is running at 100% for both cores in C1 Pro for eath conversion, it drops a bit between eatch picture..

    I haven´t LE on this computer.
