Catalina, PM 6 & Headache. Super slow experience

HI Kirk,
Will give these settings a go...
zhpenn:
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

Hi Kirk,
It does seem faster. Thanks

Hi Kirk,
Still having the same issue as the OP. I have the same settings you have recommended above however the need to have Previews: Enlarge photos to fit previews and slide shows, turned on is a must.
Version 5 was blazing fast with that turned on, however version 6 is only as fast with that turned off. Its a trade off of using half the size of my screen for speed or full screen to make quick judgements on focus and be able to lean back from the monitor.
was there that much of a rewrite in that part of the code that it cannot be turned on again without sacrificing the speed.
With it turned on, its moving through images at around 3 images/sec, with it off, its blasting through them just like version 5 at somewhere near 10-15/sec. There is also a noticeable lag with it finishing the keyboard buffer on the right arrow letting two more images pass after letting go of the key.
I had to move to version 6 upon upgrade though I have had it for several months when it was released, I was still using version 5 until 6 was sorted out. Now its my only choice and hoping that the bugs can be found.

Usually that feature kicks in when you have a very small source image and a large preview pane. What kind of images are you previewing? What resolution do they have (width and height)?

On our end? No. On Apple's end, it's hard to say, but scaling images as they're drawn (that's what the "Enlarge photos to fit" feature does) is much slower for a modern app (meaning built with a newer SDK and 64-bits) than for an older app like PM5 that appears to benefit by some sort of emulation.

If you're holding down the arrow key and the key events begin to come in at the rate of your keyboard repeat rate setting, then that problem will occur when PM can't move through the images at that rate. You let up on the key but the event queue still has a few more "right arrow key events" that continue to be delivered to PM and it obeys.
Could you make a video of your browsing with the "Enlarge to fit" on and off so that I can see this in action? Please post a link to it when you can.
Thanks,
