Is this just the sorting issue you reported earlier?

yes, the problem is on  Reply #6

====
I found that on MacBook pro 2018(6-cores), scrool through images is a lot slower than a mac pro 2013(with 2560 x1600 monitor),

not sure if it is because of the screen resolution, but on MacBook pro I already set to fastest preview.

I use the same pm 6 setting on both mac.

when pressing the arrow key faster(or long-press the keyboard arrow, key repeat speed already set to fastest ), the speed of switching photos is still slow,
no matter how fast I press the arrow, it will look like there is a speed limited on it.
when selecting photo actually feel very laggy

but on a mac pro, the speed of switching photos is as fast as I press the arrow.

please check the video, will be deleted after kirk sees the problem, because of clients' privacy
the first half of the video is on RMBP, the 2nd half is Mac pro

Did you turn off the "Enlarge photos to fit previews and slide shows" checkbox in the Preview page of the Preferences dialog?

I watched your video.  It's hard to tell what's going on because the video is from a cell phone camera and isn't a screen capture.  But it certainly seems to be moving along at several frames per second.

Please post screenshots of your preferences pages, specifically the Contact Sheet, Files, Preview, Caching, and Render Cache pages.  Use the 'Attachments and other options' link when you're composing your reply to this message and there you'll be able to upload your JPEG format screenshots.

Thanks,

-Kirk

Hi Kirk,
I now put two screens next to each other filming in the same frame, you can see there is a very big difference
http://bit.ly/2oOhyWu

and here is the setting screenshots
http://bit.ly/2pFiP1O
and this two options I did try turn off but it makes no difference, so I turn it on again because I do need this two function.
turn off "Enlarge photos to fit previews and slideshows"
turn off "Synchronize single selection between Preview and Contact Sheet"

can you please have a look and check where is the problem, thanks a lot

Suggestions:
In the Contact Sheet tab, change the High DPI Display Quality to "Best (uses more memory)"
In the Preview tab, change the High DPI Display Quality to "Best (uses more memory)"
I'd also suggest turning those two check boxes back off.  They should make a difference.
In the Caching tab, I'd set your Memory Cache all the way to the left (10%).

If none of this makes a difference then I'm going to have you turn on some logging and test previewing and get the log to me.

Hi Kirk,
Thank you, I have tried all your suggestion. I think I found the problem.
Only need to change 2 of the setting. The Preview tab, change the High DPI Display Quality to "Best (uses more memory)"
and turn off the "Enlarge to fit" at the same time, will make it faster.

If I select the Standard (fastest) Quality, the image does show larger, but it becomes slow again.

but this actually not feasible, because if I turn  "Best (uses more memory)"  on, I can not use the full screen, a lot of my image only shown 1/4 of the size of my 15-inch MacBook pro. hard to see the detail of the image.

I'm not sure if this problem happens in all High DPI monitors, like 4K monitor?

But is there any way on your end that can optimize this performance?

thank you very much.
