2016-12-14 02:25:21 -0600 | commented question | OpenCV slow on retina screen vs external screen Yeha but that much? I mean I can only push 10 fps and in the other screen I can push well over 30 fps... I would assume the GPU would take care of it, maybe the UI facilities in mac aren't accelerated? |
2016-12-13 03:59:12 -0600 | asked a question | OpenCV slow on retina screen vs external screen I have noticed a really weird behaivor of OpenCV on my Macbook 12 retina (Early 2015 model). I am using OpenCV 3.1.0 and Python 3.5.1 on Mac OSX El Capitan 10.11.2 When I put a window in the external screen (27" 1920x1080) the code runs fast but when I take the same window and move it to the builtin screen(12" 2304 × 1440 on the default settings) the code runs alot slower. Here is a minimal code that shows the problem: When running on the external screen I get: When running the exact same code on the retina screen (i.e. the window is being rendered there): I tried it a bunch of times and the results are consistent, any idea what might cause this? |
