Hardware Acceleration

Slovakbrit
Just upgraded to C1 version 11 and two things are not right, first it is telling me "Hardware Acceleration doesn't work" in Preferences, but i have not changed any hardware since C1 Version 9 and it always worked till then, the other thing is when I tell it to print it now takes ages till the print dialog comes up, this I never had a problem with till this version, any ideas as paying for something that is going slower than the version I had before is a bit annoying. My graphics card is an AMD Radeon RX 470 Gaming X 4G which has been fine till now.

    So you have installed C1.

    Have you tried closing C1 and restarting (I would guess yes.)

    Have you tried rebooting the machine?

    I have not seen those problems (Win 7) so I would suggest there is something not right with the installation for some reason. It may be related to a number of things including old undeleted temporary files.

    You should also force C1 to re-assess the GPU (assuming it is not set to "None" under hardware acceleration in the preferences.)

    ETA: CLear the files from here to force the re-assessment.

    C:\ProgramData\Phase One\Capture One\ImageCore


    (Win 7 - same or nearly the same in other versions.)

    Same problem for me but it was on my two computers disabled with v10. But after upgrading to v11, the hardware acceleration was enabled on the slowest.

    On my other computer (nVidia Geforce - optimus technology) i canont enable hardware acceleration. It works with Photoshop, Lightroom, Lytro desktop. Stange.

    I have tried to remove the OpenCL file but it doesn't work better after
    What are the minimal specs to enable OpenCL ? v1.1, v1.2, higher like 2.0.
    The page in PhaseOne OpenCL/HW acceleration support is outdated.

    Thanks,

    Need at least 2GB RAM but even then if the likely performance is not great the CPU will be preferred and the GPU bypassed.

    My Notebook has 2GB RAM on the GPU but the card itself offers marginal power.

    I saw some action on a GPU monitor program using C1 V9. Nothing of evidence in V10 testing.

    V11 seems to make use but maybe not much when editing. I have not checked specifically for output processing.

    Back in V7 and V8 days I had an odd situation whereby the startup would report that there had been a previous assessment that suggested the GPU has no useful performance and to the test was being aborted. I think that was reasonable - the GPU seemed fast enough anyway, so I didn't dig into that very deeply. It was not resolved until V9 installation as I recall.

    I have only 1GB graphic memory...
    Bad news.

    Ok SFA, thanks for the replies, I have sorted out the GPU problem by going to C:\ProgramData\Phase One\CaptureOne\ImageCore and deleting the files, you were talking about RAM and OS, I am running the latest version of Windows 10 and I have 32gb of high speed ram which i mainly use for video apps and 4gb on the GPU so no problem there.
    It took about 5 mins to set up the hardware acceleration but now its good, the printer thing i am going to look into, it is a Canon IX4000 and is quite old but still good, the problem is they have not updated the driver for a couple of years which could be to do with it.
    I will let you know if I find out anything that would be relevant to C1

    Mike,

    FWIW my old printer is a Canon iP6600.

    The driver and its interface can have its moments but is much better with C1 than it is with software I have used previously.

    When I select Print the screen appears in about a second or so.

    Sadly that's about as much as I can offer in terms of what I have seen so far.
