Cannot enable Open CL

Nelson Chen
I upgraded my video card to a Radeon HD 5550 with 1GB memory which is on your Open CL supported list.

Then I installed the latest ATI driver 10.11 with Open CL my Vista x64 system. The driver was downloaded from:

http://sites.amd.com/us/game/downloads/ ... -64.aspx#1

Next I restarted Capture One Pro 6.0. But the Open CL option is still grayed out and set to never.

I then imported the registry file UseOpenCL.reg which sets the value:

HKEY_CURRENT_USER\Software\Phase One\Capture One\UseOpenCL=1

Restarted CO 6.0 Pro. The Open CL option is still disabled.

What did I miss?

Thanks,

Nelson

    I opened a support case and got this answer.

    "Please reference the supported hardware at the bottom of the link below;
    http://www.phaseone.com/en/search/artic ... nguageid=1

    We are always working on improving supported hardware.

    Kind Regards,
    Phase One Support"

    I wish the support person actually answers the question instead carbon copying support links. My video card was purchased by on that link. My video card is an AMD ATI Radeon HD 5550 with 1GB memory.

    I upgraded my Catalyst Suite as well to 10.11.
    Try going to the individual downloads tab, and download the CL driver only.
    I installed it by itself.
    I dis-installed the CO6X, and then reinstalled it.
    I did that, and was then able to get the Open CL to work.

    Though slightly different from you, I am running Win 7 64.
    More work than I thought necessary, but it does work now.

    Jim,

    Thank you for the reply. I did try uninstalling CO 6 Pro on my Windows 7 x64 partition and reinstalling it. It did not enable the Open CL in CO 6. I do not think it would be any different under Vista x64.

    I noticed that you have more powerful CPU and GPU, Intel i7 920 and ATI Radon HT 5700 than mine, Intel Core2 Quad Q9550s and Radeon HD 5550.

    This was the reason I asked the tech support folks for a confirmation about my video card. Instead they just repeated the party line (the list of supported cards) which was not helpful.

    At this point, I am also thinking about building a new Intel i7 machine for CO 6 with a more powerful GPU like the Radeon 5750.

    Jim,

    I just tried your suggestion/

    1. Uninstalled CO 5.0 and 6.0.
    2. Cleaned up the program files directories
    3. Cleaned up the CaptureOne files under c:\Users\<userid>\appdata\local.
    4. Reinstalled CO 6.0.

    The Open CL is disabled.

    I would like to know the algorithm that the CO 6 uses to determine the eligibility of Open CL. It obviously does not agree with the KB article.

    Unless you did it as well, as I can't 100% tell from your post, I downloaded and installed the CL driver separately. I was then able to verify it was loaded.
    Then I loaded my CO6X.

    We have tried to accomodate as many GPU cards as possible. Unfortunately we do not have access to all cards out there, and our recommendations towards families of cards were in some cases based on "specs" from the manufacturer.

    It turns out the AMD 5550 card is not supported currently. Only AMD 57xx and 58xx cards are supported as of today. We do stride to include as many cards as possible in future releases. To some degree we are unfortunately bound by the OpenCL driver from either AMD or NVidia.

    We are about to release new recommendations for the "best experience" system. For Win 7, 64bit the NVidia "Fermi" series gives the absolutely best performance as of today. We have great performance using NVidia 480GTX and 580GTX cards.

    Thank you for the clarification. I guess I have to return my 5550 and get a more expensive one. Who would've thought the photographers need 3D gamer strength cards just to run Open CL?

    At $449 and $549, the GTX480 and GTX580 are out of the question. Each costs more than the powerful Intel i7-870 Lynnfield processor I am building my next computer with.

    Can you clarify which ATI 57xx series are supported? I do not want to waste my money again just to find out it is not supported. Is 5750 supported?

    Thank you!

    Well I hope the 5770 is supported as I have just bought one ☹️ as something my wife can wrap up and give me for Christmas 😄 . For that reason I won't be able to check if it works till 25th Dec. I chose the 5770 on the basis that it's the card in all the Mac Pros and if it works in a Mac it should work in a Windows 7 64 bit machine.

    This is symptomatic of this whole release, the programme is not ready, particularaly the express version. If this had been an Adobe Lightroom release it would have been put out as a time limited beta release - it's not yet at the stage that Adobe would put out a trial of a programme as a release candidate. I do object to having to pay to do your beta testing for you.

    Jim,

    Can you clarify which ATI 57xx is in your computer? There are two 57xx models: 5750 and 5770 according to Newegg. I would like to get one that has been reported working.

    Thank you!

    I have the ATI 5770. It seems to work, and with my config I have not had any crashes. I have, however, experienced some issues with the clarity slider, (see another post).
    Good luck,

    Interestingly enough, the nVidia GTS240 (1GB) seems to work too, despite not being on the list of supported cards.

    Installed the latest drivers 260.99 and the option to select Auto/Never was there in the preferences. This is running the 64 bit version of C1 Express v6 under Windows 7 Home Premium 64 bit.

    If you install the latest AMD driver 10.12 (as of Dec 13) and the just released 6.0.1, all AMD 5xxx 1GB cards should work.

    With the new release, the behavior on my system just got worse. Now, all the view windows break down whenever I move a sider - exposure, clarity, etc.
    When I turn off Open CL, everything is fine.

    Not sure whether you have an AMD/ATI video card, but if yes, did you update to the 10-12 driver/OpenCL version of 13 Dec 2010?

    Yes I did.

    The breakdown is quite different than before. Now it is the upper half of a photo. "Real time" adjustment is impossible.

    Now I am very confused - but happier.
    I restarted, and opened CO6 only. Same effect; even on different files.
    I opened up my browser (Chrome). CO6 went crazy on the one file I was looking at - it ended like it was cropped to a couple of pixels in size.
    But when I looked at another photo, I did not see the same breakdown on moving any of the sliders.
    This is now the case on a few photos - no viewer breakdown.
    I reset the broken photo, and life seems ok now.
    It's almost like something was reset someplace. Makes you love software.

    I spoke too soon.
    The program crashed on me when I was scrolling through 198 photos in filmstrip mode.

    I restarted CO6, and the problem with the sliders is back.
    I did some screen captures which I will submit.

    I installed 6.0.1. The results were not good. It has gotten worse.

    1. On the Windows 7 partition, with the ATI 10.12 driver and a fresh install of 6.0.1, the thumbnails were all corrupted.
    2. Open CL is still grayed out.
    3. Rebooted and started CO 6.0.1 again. Now it was crashing when in the folder with KS adjustments.
    4. Rebooted back to Vista x64 also running 10.12 driver. It was crashing also on the folder with KS adjustments.
    5. Brought up 5.2.1, it was not crashing on KS adjusted images. Of course it does not understand KS.

    I uninstalled CO 6 and 5, cleaned up everything according the KB article and will try again.

    This has not been a good experience.

    Hi Nelson.

    The reason OpenCL is greyed out is because you have too "cheap" of a GPU. Internally we measure the performance of the GPU, and yours have only "4 compute units". The minimum we require is 6. The reason for this check is to make sure the display update is done quickly.
    When OpenCL is turned off automatically, the rest of Capture One should function great.

    As far as I know you have already filed a support case. This is needed to into the specifics of you file and error scenario.

    Lionel,

    Thank you for the confirmation. I agree with you that all AMD 5xxx 1GB cards should work.

    However, I am still not able to make Open CL available through COP 6.0 & 6.0.1 with ATI/AMD 10.12 driver, on 64-bit Vista or 64-bit Windows 7 with the AMD 5550 1GB card.

    I have installed and installed COP 6 or 6.0.1 a few times without success. With the registry value useOpenCL set to 1, COP 6.0.0/6.0.1 came up with the Open CL option grayed and Never was displayed for the grayed out option box.

    Is there anything else I could try?

    Thank you!

    I would like to comment once more:

    1. You do not need a graphics card for Capture One 6.0.1 to work.
    2. You need a really capable GPU card for Capture One to benefit from it.

    AMD and NVidia makes about 100+ GPU cards. We have not been able to test all versions, and the statement "5xxx cards from AMD should work" refers to the driver being able to compile the code we create.

    It turns out we have another requirement build into the GPU processing pipeline. We measure the performance of the card (given it is compatible in the first place). This performance number we require to be rather high, to be able to give the user the best interactive experience. In the case of the 5550 card, the performance is just too low, and we disable it automatically. This is not a bug, but just how we decided to make sure the interaction speed will be high enough.

    If you have a nice dual CPU machine with 16 cores, you need a really good GPU to measure up. We have tested cheap GPU's as well. The NVidia GTX430 cost about $100, and it runs fine.

    Low end AMD cards like the 5500, 5550, 5450, 5000 does just not have enough compute power to run our algorithms in real time. This is also true for many older cards from both NVidia and AMD. It makes no sense to support these since the experience will be poor.

    Advice to save money: buy a cheap "fermi" based NVidia card, or live with the standard "5.x" interactive speed.

    I can imagine we will get better optimization within the GPU code over time, hence add support for cheaper cards in the future.

    Low end AMD cards like the 5500, 5550, 5450, 5000 does just not have enough compute power

    That about 5670? Your test it? It have enough power?
    (Open CL not working now)

  • Lionel12
    We have not tried the 5670. Based on specs, I would think only 57xx, 58xx and 59xx from the 5000 series will have enough processing units.
