Very slow preview rendering when making adjustments

psenz
I've found that the rendering in C1 9.0 is super slow compared to C1 8.3.3 when making any sort of adjustment. It's slow with Open CL on, amazingly slow with it off. I've tried adjusting preview size and everything else I can think of.

I have a mid 2014 MBP, pretty much maxed out. This is making me very hesitant to purchase a new license, though I do really enjoy the new features.

Anyone experiencing the same thing? Any ideas?

Thanks! 😎

    If you'd all share a bit more information, maybe there is something that you have in common.
    E.g.
    - what kind of images files? JPG, TIFF, DNG, RAW (which camera)
    - where are the image originals stored?
    - only on certain adjustments or all of them?

    -RAW's from Nikon (D600, D750) and Canon (5d, 1DsMkIII)
    -Images are stored locally on my MBP
    -Most adjustments... I'd say 90% of the time, the actual rendering of the adjustment takes way slower than it ever has on C1 (been using since 6.3.3).

    I think there is something with C1 9.0... Perhaps it's a larger memory hog than it lets on? If so, that's a huge reason to not upgrade as I was very very satisfied with the speed I got with C1 8.3.3.....

    If it uses more than the available free physical memory and the OS starts swapping memory to disk, then it would certainly get much slower.

    I have the same issue, except it uses up all my 32 gigs of memory, and my computer begins to shut itself down by stalling all apps and freezing my computer.

    I have to reboot every 20 min in order to continue working in Capture One (9,0).

    I contacted them, and they sent me a note back about there being a memory leak for Canon users only (I do shoot Canon) but I have seen many unhappy Nikon users as well.

    So we will see. Hopefully a fix soon!

    For me it is a Mid 2010 Mac Pro, 2.8 GHz Quad, 16 GB RAM, 6G SSD and Sapphire 7950 graphics card.

    Capture One 8.x flew on it.

    RAW files from Nikon D810, D750, Canon 5D Mark III
    All files on 6G SSD but C1 v9 is even slow when there is no access to the files and it's working with the previews.
