C1 is slow with lot of lag in applying adjustments and layers (on iMac)

    I have a noticable lag when working with DNG files (coming from Lightroom).

    No problems with camera raw files (Canon CR2).

    MacBook Pro (16 Inch, 2019), 2,3 GHz 8-Core Intel Core i9 with 32GB RAM.

    My experience is similar, perhaps slightly less impacting (I have a more powerful laptop), but sure I do have to wait a bit before seeing the changes applied. When it's a matter of fine tuning with a slider it's really annoying and time consuming.

    Older versions weren't like that, so it's a regression.

    99.9% of files I'm working on are Sony ARW.

    Will I answer to a guy who is so concerned about staying anonymous behind a "FirstName LastName"? Maybe once... How much RAM did you order in your iMac? How big is the size of the preview thumbnails? standard size can be a bit small for your display. If you have no additional graphic card AND smaller than 5K thumbnails, the processor always has to calculate the bigger pictures.

    But yes, Capture One is at times not the most speedy app, but hey, therefore you get some crashes for free. I've the feeling the app punishes me if I become too hasty or want to work too quick, according to it's maybe Danish standards...

    Sorry to disturb you, guys, but I have an old MacBook Pro 15" Retina late 2013 with 16GB RAM and a Nvidia GT750M 2GB, under Mojave, and I don't have any lag in developing my pictures.

    Thank you for your responses.

    Mario: Yes I didn't think of that, I have always converted all my images to DNG when importing into Lr, and right now I am working on a mix of newly shot images (CR2) and some from LR (DNG). Will keep an eye to see if the lag is specific to DNG types.

    Fabrizio: Yes I am facing similar lags while changing sliders.

    Joachim: Well now I have a name:). Thanks for pointing it out, didn't even notice it myself. 24 GB RAM, preview thumbnails of 2880 px, and Radeon Pro 570 4 GB Graphics card. And oh I crash-land at least thrice a day.

    Robert: Pls let me your laptop :).

    FYI, I work only with dng files for years, now.

    Are you using catalog or sessions? If you imported thousands of images into a catalog and it hasn't finished rendering proxies (they call previews, but they're a sort of 'raw' proxy files instead), things may be havoc for a while.

    I don't know the exact routine for the Mac version, but on Windows it can take a good half hour to initialise the OpenCL API for hardware acceleration to start working, and if you close C1 before it finished or of it crashes, it'll try again next time.

    Check for a status wheel up top centre right of the cursor tools.

    What you described is essentially the rendering process/architecture of Capture One, with the difference that if all is well, it goes by fast and smooth.

    Gustavo: I am currently working in a Catalog. And have a total of ~1500 images in it - just doing a trial run of C1 at the moment. 

    I think C1 has already done the run of creating previews, I also did so manually from the Image>Regenerate Previews command. 

    Hopefully it should become faster as the images settle down and C1 becomes more familiar with them :)

    I have a 27 inch Imac with I9, 48GB Ram, 500GB of SSD and Thunderbolt External SSD and the same lag problems.
    I use sessions not the catalog.
    As well as with the sliders also with the brushes while drawing the masks.
    I left the size of the thumbnails by default, I will try to increase them, do you have any suggestions on the ideal size?
    However, I have the impression that the code is not optimized, I am also trying the 22 Beta version and it does not seem to me that things have improved.

    Do you have any other suggestions please ?

    Regards

    Luca

    Luca - Nope I don't have any suggestions at the moment, I am still facing the same lag issues. The C1 team reached out to me to create a performance report and share the details with them for analysis. Has been a week, they haven't reverted as yet. 

    I suggest you reach out to C1 directly through this forum.

    Luca, usually, the preview image size which yoiu set in the preferences (what you referred to as "size of the thumbnails") should be the size of your monitor resolution, or the next above. How much that helps I don't know.  C1 tends to be slower with hi-res (4k or so) monitors, slower than many would like it to be.

    Note that you need to select the images and rebuild the previews (menu image>regenerate previews) as otherwise they remain the size they were created before.

    hello guys, I switched my windows pc and working on my new MacBook Pro 16 m1 pro. I work very often with luma range and it is very laggy. The switcher for reverse need so long. On my Windows PC works instandly. 

    All option with the luma range are not responsive. Even to move the luma range window.
