Eusebius Posted September 1, 2018 Share Posted September 1, 2018 Hello, In a quest to optimize Affinity Photo's speed on my relatively new 2017 MacBook Pro (2.9 GHz Core i7 w/ 16 GB RAM and AMD Radeon Pro 560), I enabled the "Metal Compute Acceleration" under Preferences > Performance. Since this Mac also has an integrated Intel 630 graphics card that seems compatible with the option, I thought it would help. To my surprise, it completely slowed down Affinity Photo and made something as simply as dragging a plain rectangle on a 1920 x 1080 canvas blocky, choppy, and unusable. Shouldn't this option do the opposite? Quote Link to comment Share on other sites More sharing options...
firstdefence Posted September 1, 2018 Share Posted September 1, 2018 I'd stick with OpenGL for now, there is a bit of a bug with certain cards, It might get better in v1.7 Quote iMac 27" 2019 Somona 14.3.1, iMac 27" Affinity Designer, Photo & Publisher V1 & V2, Adobe, Inkscape, Vectorstyler, Blender, C4D, Sketchup + more...

JDub Posted September 7, 2018 Share Posted September 7, 2018 Hi. I'm also looking at speeding up performance while working on a 36MP masking task and have been looking at these options. OpenGL is only for display purposes, so are you saying to switch off metal compute for image processing? Quote Link to comment Share on other sites More sharing options...
