CC Hogan Posted August 31, 2019 Share Posted August 31, 2019 I am not absolutely positive about this, but I have been suffering from Affinity Photo running slow with lag, but it appears to be only when I have my charger plugged in. Anyone else have this? I am doing some artwork 5000 square at 300 with quite a few layers. Most of them pixel paint layers. This is the 2ng gen iPad with the current iOS (12.4? ish?) All the best CC Quote On a fun little learning curve with Affinity. Or a vector curve. One of the two. Just a writer learning to draw. Link to comment Share on other sites More sharing options...
Staff Dan C Posted September 1, 2019 Staff Share Posted September 1, 2019 Hi CC Hogan This isn't som,ething I've heard of before - in order to best test this could you please upload a copy of your .afphoto file to the following link so I can test directly with your layers etc? Thanks in advance! https://www.dropbox.com/request/q0HjF3G10mox5qgmUlkp Quote Please note - I am currently out of the office for a short while whilst recovering from surgery (nothing serious!), therefore will not be available on the Forums during this time.

CC Hogan Posted September 1, 2019 Author Share Posted September 1, 2019 Okay - done that. I had this the other day on a different (but similar file), but I didn't think about it until it happened again yesterday. I thought it was just one of those moments! When it happened, I noticed that the screen on the iPad was getting warm under my hand, so perhaps this is a mixture of a large (ish) file and the charging. I had been working on it for an hour maybe? I am using the larger Apple charger - the 30w one. Quote On a fun little learning curve with Affinity. Or a vector curve. One of the two.

Staff Dan C Posted September 3, 2019 Staff Share Posted September 3, 2019 Thanks for your file - I've been testing this here using a third Gen iPad Pro & the 87W MBP charger. At first there was no noticeable difference with or without charging, however after around 1hour I noticed the app started to slow slightly, and my CPU usage (shown in a third party app) dropped. At this time, the iPad was noticeably hot to the touch, and I suspect this is the CPU thermal throttling - with both the Affinity app using as much resources as possible and the battery charging at a higher rate/wattage that usual - the iPad is overheating slightly and throttling back the CPU speeds to account for this. Unfortunately not much can be done regarding this, as cooling/throttling is all taken care of by Apple/iOS and we have no control over this - my apologies!

CC Hogan Posted September 10, 2019 Author Share Posted September 10, 2019 Thanks, Dan - sorry about my late response - I missed a notification. Since I posted this, I have been suffering sporadic slowdowns without charging and without the iPad getting hot. Just now it was on a 300 dpi 8000x4000 image with only 4 pixel layers. Suddenly it was lagging, and when I returned to the home screen, it took about 3 minutes to save. Once it had, then it seemed to be okay again. you mentioned that Photo always uses as much resources as possible - could there be occasional resource fights going on with any background processes? (Sorry, I am a bit ignorant about iOS!) Quote On a fun little learning curve with Affinity. Or a vector curve. One of the two. Just a writer learning to draw.

Staff Dan C Posted September 11, 2019 Staff Share Posted September 11, 2019 No problem at all I'm sorry to hear this, our QA team have been testing documents roughly this size and have reported similar issues - these are logged with our development team and we're working hard to put this right! 13 hours ago, CC Hogan said: could there be occasional resource fights going on with any background processes? (Sorry, I am a bit ignorant about iOS!) There certainly could be, but I too am far from the authoritative figure on iOS - AFAIK we use all available system resources, but as for the hierarchy of which processes come first I don't believe Apple publicly share this information - apologies!
