Capture One 20 slider lag

[LiE_]

I've been testing Capture One 20 Fuji Express the past few days to see if it can replace Lightroom. Overall I'm very impressed but I have a show stopper.

When I'm editing and adjusting the sliders, the changes don't appear until a few seconds after. It isn't instantaneous like in Lightroom which makes it impossible to fine tune. For example as I move the shadows slider the image doesn't change, then when I stop moving it 1 second late the change takes affect. Is this normal? Any settings I can change?

I just did a quick test adjusting HDR and Exposure sliders on a range of file types and sizes in C120 (Leaf/Phase, Nikon, Fuji) and the changes were more or less instantaneous on all. For grins, I ran them through LR for comparison, and while I'd probably give LR the edge here, it was very slight. This is on a 2017 MBP with the 4GB radeon pro GPU. In Preferences->General, I've got hardware acceleration set to auto for both display and processing, and under Preferences->Image, I've got preview image size 2560px. Those tend to be the settings that would have an impact. Here's a KB article from Phase that provides a broad overview of performance considerations (from their perspective, anyway). https://www.phaseone.com/en/Search/Article?articleid=1720

Thanks, I suspect the GPU is what is letting it down. I have a 2018 Mac mini with the LG Ultrafine 4k. The URL you provided recommended 4GB RAM.

Generally speaking, any GPU that supports OpenCL 1.2 or newer and has a minimum of 1GB of dedicated RAM will be utilised. However, for more intensive processes, such as processing large files and using local adjustments - we recommend having at least 2GB of RAM.

When it comes to high-DPI displays such as 4/5K iMacs, this differs slightly. For any high-resolution displays, we recommend a minimum of 4GB of dedicated RAM.

I’m not terribly familiar with the program, but is there a performance section in the settings that would allow for enabling GPU acceleration or for memory settings?

You could try to set the hardware acceleration to Never for Display or both Display and Processing. It is in the Preferences, General tab.

I suspect it's the GPU. I'm using version 12, and I remember having an exchange with someone who said it was laggy on the Mac. We compared screen-capture video from both our systems; even though I was editing 50 megapixel files and he was doing about half that, I had real-time adjustments as I moved every slider, while his would take up to a second or two. Processors and overall systems were the same, but my graphics card had more RAM and was just a hair better.

I'd check some of the settings first, but barring that, the next thing to try might be an eGPU. BlackMagic makes an all-in-one GPU solution, but it's also possible to build your own. You can even emulate the BlackMagic Pro by getting a dual-bay Thunderbolt 3 enclosure and loading a GPU into one bay and another Thunderbolt controller into the other. The Akitio Node Duo seems to be a popular enclosure for this type of setup. Alternately, I've seen someone load two GPUs into the enclosure, and the benchmarks were even better compared with a solo GPU in there.

Admittedly I've never tried Lightroom, but going from Aperture to Capture One was pretty nice. I really like the editing capabilities in C1, although I wish it were a little faster to show previews so that culling photos would be easier. Aperture was still better, there, although Photo Mechanic is the best I've ever seen...
