    Very slow zoom

    Hi Chris, the CPU is an i5, 3.4GHz, quad core. GPU is 4GB Radeon Pro 570. Kind regards, Thomas

  3. Hi, I can't post this image here but you could post a dropbox link for me. Kind regards, Thomas

    Very slow zoom

    Hi Chris, you already have the 500MB 16bit panorama file with the zoom problem, don't you? I don't have any other file with this problem, but I can still easily reproduce the problem with this file. With this huge file zoom in will always "hang" when zooming for the first time and with metal compute enabled—sometimes a second, sometimes even longer. Otherwise I see a performance increase with Metal compute enabled (but a decrease in quality, see new thread). Kind regards, Thomas
  5. Hi, Enabling "Metal compute acceleration" reduces the quality of image rendering when using live filters, e.g. the clarity live filter. Here are four screen shots to show the effect. The windows on the left side are without "Metal compute acceleration", the windows one right side have "Metal compute acceleration" enabled. The top screen shots are taken the clarity filter off, the bottom ones with the clarity filter on. The clarity filter was set to 0% (no effect). As you can see the rendering of the image on screen gets blurred with metal compute and the clarity live filter. If you export the image or merge the pixel layer with the liver filter, the result will be ok (no blurr). Please look at the image attached in 100% zoom in order to see the effect. Edit: The image file is RGBA/16. iMac Retina 5k, Mojave 10.14.5, Radeon Pro 570 (4GB), 48GB RAM This bug makes it impossible to judge image quality with live filters. Kind regards, Thomas

    very slow since update to 1.7.0

    Did you read this (I am having the same problems with "Metal Compute")? So it seems that this is "normal" and the "solution" is to turn "Metal Compute" off.

    Hey Chris, while this may be a usable temporary fix, it's certainly not a satisfying solution. To quote from your Affinity Photo 1.7.0 announcement: So you say that an iMac 5k (2017), i5 3.4GHz, 24GB RAM, Radeon Pro 570 (this is a "powerful discrete AMD GPU in modern Mac hardware", right?) does not profit from these changes? What kind of Mac hardware would fulfill the promises made in your announcement? Monday morning edit: I beg to differ. Metal compute on my old rusty Quadra 650 iMac Retina 5k speeds up (or should I say "makes them less slow" …?) actions like live filters noticably. Disabling metal compute is therefore not a good solution and it's certainly not the best configuration on my iMac. Kind regards, Thomas

    I have tested these three combinations (Sorry for the confusion caused by the fact that I'm using the german user interface):

    I have two iMacs with the same specs (at work and at home). Now I'm back home with 1.7.0. The problem is clearly related to metal rendering. I have just turned off metal rendering in the Affinity Photo 1.7.0 preferences and the problem went away.

    Hi Chris, done. Kind regards Thomas

    Very slow zoom

    I just went back to Affinity Photo 1.6.7. 5 minutes later, same Computer, same OS, same file: No problem with zooming. Kind Regards Thomas Bildschirmaufnahme_2019-06-07_um_09_48_38.mov

    Roll back to 1.6.7

    You could try to recover these files/folders from your time machine backup: ~/Library/Preferences/com.seriflabs.affinityphoto.plist ~/Library/Containers/com.seriflabs.affinityphoto/ ~/Library/Application Scripts/com.seriflabs.affinityphoto and all "xxx.com.seriflabs …" folders in ~/Library/Group Containers/ I hope that's all … "~" is the placeholder for your home folder. Kind Regards, Thomas

    Very slow zoom

    I am pretty sure that yesterday I had the problem when zooming out after having zoomed in. Today I can reproduce the problem by simply zooming in. Please see screen movie attached. The afphoto file (created with 1.6.7) has 537MB, 15692 x 2375 px and is RGBA/16. Kind regards Thomas Bildschirmaufnahme 2019-06-06 um 17.20.26.mov

    Very slow zoom

    Hi, I've opened a panorama (approx. 15000 x 2500 pixels, RGB 16 bit) which was saved as afphoto file with the last 1.6 version (it was the last file I had worked on with 1.6). It has 2 pixel layers and one tone mapping layer. I can zoom in with the "alt" key and the scroll wheel and it's reasonably fast. When I try to zoom out again, I get an extremely blurry image, which looks like a scaled up version of the first (fit-to-screen) view of the file. It takes a second or two until I get a sharp image. On the same file in 1.6 zooming with the scroll wheel happened pretty much immediately. iMac Retina 5k 2017, Radeon Pro 570, Mojave 10.14.5, 24GB RAM, 512 GB SSD, default Affinity Photo 1.7 preferences (e.g. metal is activated). Kind regards Thomas
