speed compared with Photoshop in Affinity on Desktop Questions (Mac and Windows) Posted October 19, 2018 Does anyone else have issues with the speed of Affinity Photo. My desktop with i5 chip, 8gb ram & Nividia graphics [1gb dedicated ram] hardly ever keeps me waiting in Photoshop. Affinity Photo is frustratingly slow. 24mp RAW file takes over 10 seconds to load. Develop mode takes almost as long to complete, & flattening the image from 5-10 layers takes several seconds, which is virtually instantaneous in PS. This makes it a frustrating experience! In addition, if you use any of the tools, as soon as you release the mouse, it processes your action [ slowly!]. This means, for example, if you use the selection brush & want to select a second area, you have to wait while it processes the first area. Sorry, but for a program which has received so much advertising hype, this just doesn't cut it.
