DebB Posted April 16 Posted April 16 I am using Affinity 2.6.2 to stack and edit my Astro work. I began on an M1 macbook pro with 16G ram, but have recently bought a PC specifically for this work as the Mac was struggling to render properly with larger stacks. I am finding the software even slower than my MBP, and there is a lot of lag when applying edits to the images. Rendering is also not great, with some poor results. It is so disappointing! The PC has i7 12700, 64GB Ram, 4TB SSD and Geforce Nvidia 3060ti 8Gb. Benchmark and performance settings attached below. Is there anything I can do to improve the performance? Quote
NotMyFault Posted April 17 Posted April 17 The benchmarks of you new PC (2025) shows only an improvement by factor 2 over my 2020 M1 iPad (or similar spec Mac mini M1). And in many cases the M1 based Apple devices perform (perceived) better than Intel based computers even with same benchmark results. Perceived perform is influenced by many factors. To get a clear evidence, run identical jobs on both machines and compare runtime. It should reflect a factor of about 2 on average. If results deviate severely, it is worth investigating deeper. Otherwise you got what you paid for. I got a replacement M3 MBP for my company Intel i5 Laptop and perceived performance difference is huge.

mopperle Posted April 17 Posted April 17 What makes me a bit wondering is that in your performance settings below Hardware accelleration it lists besides you Nvidia card the onboard graphic chip. Something I do not see on my PC where I have turned off the onboard graphic in the BIOS settings. Not sure whether this somehow interferes, but maybe ist worth trying to turn it off.

SunilK Posted April 19 Posted April 19 I have a related question. I own a Seestar S50. This scope only generates light frames. Can the astrophotography aspects of Affinity Photo handle just light frames or it is reliant on darks, flats etc., Thanks. Quote
NotMyFault Posted April 20 Posted April 20 As far as I know the „supporting“ frames are to improve image quality, allowing e.g. to identify defect pixel of the sensor, but you can do without it. Darks can be taken by covering the lens opening with a cap or black textile - it is not required to have specific HW. PS: seems you don’t need darks https://bbs.zwoastro.com/d/17144-dark-bias-and-flat-images/6 Quote Mac mini M1 A2348 | MBP M3 Windows 11 - AMD Ryzen 9 5900x - 32 GB RAM - Nvidia GTX 1080 LG34WK950U-W, calibrated to DCI-P3 with LG Calibration Studio / Spider 5 | Dell 27“ 4K iPad Air Gen 5 (2022) A2589 Special interest into procedural texture filter, edit alpha channel, RGB/16 and RGB/32 color formats, stacking, finding root causes for misbehaving files, finding creative solutions for unsolvable tasks, finding bugs in Apps.

DebB Posted April 20 Author Posted April 20 Affinity can stack with or without the calibration frames. Choose ‘new astrophotography stack’ from menus. Quote
