Capture One Performance on 2013 Mac Pro

VirtualRain
Hi, I'm currently evaluating Capture One as an Aperture replacement (along with LightRoom).

I have a 2013 Mac Pro with 6-core CPU, dual D500 GPUs, 32GB RAM, and 1TB SSD (all apps/photos on SSD).

I have a pair of 4K displays (Dell P2714Q) which are 3840x2160 running at native resolution.

I downloaded the C1 trial last week (latest version) and imported about 500 RAW photos from my Canon 5D Mark III CF card to a C1 catalog (on the Mac Pro internal SSD).

I find it extremely laggy to make any adjustments such as... Dragging a slider like "Exposure" or "Clarity" or "Shadows" to the right... There is a very noticable delay in updating the preview image in the viewer. Or, using the rotation slider is jumpy and unusable to make fine adjustments. Any slider works the same. It's basically unusable.

I've tried enabling OpenCL acceleration in the preferences which has had no noticable impact.

Is there something wrong, or is this to be expected?

    What do you mean with "native Resolution"? The full 5k resolution, or the default setting in OSX?
    I don't have a 5k iMac yet, but I've seen that it doesn't Display the native 5k resolution, because it would be impossible to read any App menus then. So OSX scales by default to a good mix between sharpness and readability. Is it that what you mean? The default OSX setting?


    Yes, by 'native resolution' I mean the resolution OS X chooses by default (= default for display).

    As soon as you use a scaled resolution (in OS X system settings) your C1P gets laggy.

    Yes, it's a drawback and you have to sacrifice for not being able to scale OS X and see everything (e.g. like menus, fonts, app content, etc.) bigger in OS X. And yes, if C1P could solve that it would be nice and it would make life and reading on high res displays easier.

    And yes, if apps like Photos, Aperture, Affinity, Lightroom, etc. can handle that nicely then C1P should be able to fix that as well 😊.

    Sorry to ask again, but I want to be safe before my purchase 😊

    There seems to be a seperate option for the retina displays, where OSX scales the resolution by default.
    The native Display Resolution for the iMac 5k Screen is 5120 x 2880, but you won't see any menu item with that reslolution. Thats why the 5k iMacs have 5 scaling Options from "larger Text" to "more space". The Default Setting is the "middle setting" called "Best (Retina)". The option "Best for Screen" isn't set on the Retina iMacs.

    Here is a Review where they made a screenshot of the preferences:


    So do you mean the "Best for display" option should be set instead of the Default scaling option "Best (Retina)"?
    The first option would mean a mayor drawback for me, and to be honest, would be a reason for me to want my money back. If a company is not able to resolve this problem in a certain time (the 5k iMacs are available for some time now), they should refund the costs...

    Yes, it should say 'Best for display' in your case and not the scaled 'Best (Retina)'.

    But as OS X unfortunately has different notations on every Mac and probably as well depends on the OS X version installed, that was confusing you. But my post was meant to answer the original question and this was related to using a 4k display and a Mac Pro (late 2013) and not an iMac 5K. It says and should be 'Default for display' on a Mac Pro (late 2013) under OS X El Capitan.

    I cannot argue for an iMac 5K as I only use a Mac Pro (late 2013) and a MacBook Pro (Retina, Mid 2012). Different hardware may act different with C1P and therefore I cannot tell you what's best for you. But I totally agree that probably you won't be able to read anything on your 5K iMac should you choose 'Best for display' , because all will get that tiny. So that will probably be no solution for you then.

    I just checked with a friend of mine who got the latest iMac 5K.

    The default there, 'Best for display', equals to scaled 'Best (Retina)'. This is not the tiniest setting that can be chosen (on an iMac 5K). Best for display is the middle setting indicating a resolution 2560x1440.

    So, many words said. I cannot argue or clarify on C1P performance and optimal display setting on a iMac 5K. This has to be proofed by someone else.

    But on a Mac Pro (that needs an external display) the setting is best set to the 'default for display' (= whatever that external display is capable of displaying).

    Thanks alot for your effort!
    That doesn't sound too bad 😊

    I hope someone with a 5k iMac will tell us some real world performance findings.
