xtraa Posted November 10, 2016 Share Posted November 10, 2016 As we all know, so far the RX480 still needs a "helper-card" to get it started with full acceleration. Most of us will have a single display setup, so the second display is useless in most cases. But there is another downside: No matter if your Intel HD is running accelerated or not, the second "virtual" display – run by your Intel HD helper-card – drags the GUI-speed of your RX480 down when activated. You will notice this when you grab a window and move it to the border where your helper card display starts. So here is a tool I found to deactivate the second display. It will still show up in the display settings, but your mouse will not disappear in the "out-o-screen-nirvana", your active corners will work again and your hackintosh can focus on running the RX480 without having to mirror a slow invisible display. This is just a workaround and I am sure there are more sophisticated ways to kill the sucker, but this does it convenient and quick. https://github.com/Eun/DisableMonitor 2 Link to comment https://www.insanelymac.com/forum/topic/317831-speed-up-your-rx480-by-disabling-the-virtual-igfx-display/ Share on other sites More sharing options...
Nightf4ll Posted November 10, 2016 Share Posted November 10, 2016 you can install this with home-brew cask, but too bad it doesn't work like in windows. it does disable the display, but the gpu is still available (which is annoying, since Photoshop won't use my rx480 until I plug out the other monitor) 1 Link to comment https://www.insanelymac.com/forum/topic/317831-speed-up-your-rx480-by-disabling-the-virtual-igfx-display/#findComment-2317014 Share on other sites More sharing options...
