    I know this has been discussed before, but...

    I've just started using a 4k monitor and I notice the performance lag in rendering edits.

    One suggestion was to change Pixel Preview Size in Edit/Preferences/Image from 3840 to 5120. This makes the system work harder (thinking there are more pixels to render). It works, but the image preview softens very slightly. Since one of the reasons I stopped using HD and went 4k was to get away from the much discussed C1 preview sharpness, this solution is not acceptable to me.

    At 3840, the previews are sharper than ever. And on a machine of this spec, there should be no performance issues either.

    C1 Support suggested there might be an issue with Open CL. There doesn't appear to be.

    At my pace of editing, I can live with a little lag in order to preserve a tack sharp preview.

    Would be interested to hear of other 4k experiences and if similar lag is experienced.

    Thanks.

    Try updating the GPU drivers and use the Studio driver version rather than the gaming one. Latest one seems to be 18th Nov V441.28

    Thanks both.

    One thing I’ve noticed since I connected the 4K a week ago is that when I point C1 to a folder of images, I don’t get the scrolling green bar at the bottom of the screen.

    If I regenerate previews, the scrolling green bar does appear.

    Have yet to confirm this; but, I think that the processing lag may be occurring with images that haven’t had previews generated in the usual way.

    Any idea why I don’t see the scrolling green bar?

    Thanks.

    Interesting. As C1 created previews of a new folder of images, a scrolling green progress bar would move across the C1 quick launch icon at the bottom of the screen.

    That’s no longer happening with the 4K monitor.

    In fact, when I point C1 to a folder of images now, I'm hearing no computer activity.

    In the start bar? I have that hidden, so would explain why I've never seen it.

    That explains it.

    The same scroll bar appears when Exporting images.

    My problem is that, since I connected the 4k monitor last week, nothing happens when I point C1 at a folder of images.

    Previously, I could hear C1 (and the computer) creating previews and the scroll bar moving as it did so.

    Now, I see and hear nothing.

    I can see the images in the film strip, and if I click on one of them, it appears in the main window and I can edit it. So, no problems there.

    I'm just wondering if the lag issue I'm experiencing is due to the images not being imported (previews visibly being created) as before?

    Thanks.
