Sketch 50 and all the way down to v42 uses around 200-600% CPU whenever I try to move groups of objects around and I was just wondering if that's normal?
Here is an example Sketch CPU usage
That file is around 50mb with a couple of 2k images + some drop shadows. I'm using a 2016 MBP with touch bar, 16gb Ram, Radeon 455 and a 4k external Samsung display.
Can someone please try and create a new file, draw a simple rectangle and move it around for like 20 sec and see how much CPU Sketch is using? For me, it goes up to 175-200%.
Did the exact same thing in photoshop and it never went past 45%, Figma (in Safari) was around 80%. I find it ridiculous that 1 Rectangle and 1 artboard would use 200%.
Did a clean install, disabled all plugins, contacted support and I still can't find a solution.
Any suggestions are appreciated!
PS: read in a post that Sketch is using some "Core Rendering" thing that pretty much is 100% CPU and doesn't use the GPU at all. If that's the case, that would explain why it's struggling when the CPU needs to drive the Retina display + 4k external one. Anyone got more info on this?
